This 21-year-old, who was born in the taekwondo-mad city of Mianeh, announced his arrival in the premier ranks of the sport by winning the Asian Championships under-58 kilograms flyweight title in 2016. He did so four months before Iran's taekwondo team failed to win a single medal at the Rio Olympics.

The following year the 6ft 3in athlete took another big step up as he moved to the under-63kg bantamweight class.

After defeating Britain's current world under-68kg champion Bradly Sinden – his contemporary – 33-32 in an epic World Taekwondo President's Cup Europe final, Hosseini went all the way to the world final, taking silver after an 11-5 defeat by China's Rio 2016 champion Zhao Shuai.

Two months later Hosseini added another gold to his collection as he won the under-63kg title at the 2017 Summer Universiade in Taipei, beating Argentina's Lucas Guzman in the final.

The following year he earned golden revenge for his world final defeat as he beat Zhao 17-11 to take the Asian Games under-63kg title in Jakarta.

The year of 2018 also saw Hosseini establish himself at his current fighting weight – the under-68kg featherweight class. At the Manchester Grand Prix he was narrowly beaten in the final, 11-7, by South Korea's Olympic bronze medallist and world champion Dae-Hoon Lee.

In 2019, Hosseini continued his momentum with Grand Prix wins in Rome and Chiba. He also earned a second Universiade gold at Naples in the under-68kg category, as well as helping Iran earn team gold.

The latter success in particular augurs well for Iran's next Olympic showing.

Recalling the 2016 Olympics experience, Hosseini's coach Fariborz Askari told World Taekwondo after his win in Chiba last September: "Rio was a very big surprise for us, for three years Iranian taekwondo was in shock.

"Now, we are slowly growing up and waking up. We should use those bad dreams from Rio and change them."

Victory in Rome had been another significant marker for the young Iranian, given that his opponent in the final was Lee.

His South Korean rival recouped his reputation in the last big event of 2019, however, by beating Hosseini in the semi-finals of the Grand Prix final in Moscow, a Tokyo 2020 qualifier, and going on to take gold with a defeat of Sinden.

Hosseini's favourite technique is the arcing head kick, fired from up close. 

"In camp, we train the clinch a lot," Hosseini said. "I try to find an opening – up or down, left or right. I have a lot of techniques in the clinch: I can kick both ways.

"But for me, the first thing is the mind. In the camp, I am always thinking about the next competition, the next strategy, the next opponent – always thinking about attacking and defending."

Hosseini took up the sport when he was nine. 

He told World Taekwondo: "I saw a Jackie Chan movie and was so interested in doing martial arts. Near my home was a taekwondo club so I went there and started.

"My city is a very small town, but the only medal we don't have is an Olympic medal.

"They have every other medal: juniors, cadets, worlds, Grand Prix – everything! The dream is to get Olympic gold for the city."

In May of last year, Sim overcame a spirited performance by Iran's Mahla Momenzadeh to win her second consecutive world taekwondo title in front of a packed crowd at the Manchester Arena. 

Having established a five-point lead, the South Korean eschewed the idea of switching to defence, but went in search of further points.

"My style is to keep attacking," she told World Taekwondo in the wake of her 11-6 victory in the final. "Attacking is most important for me so I try and attack as much as I can and don't defend too much. In Korea, we are taught to continuously kick and that's what I tried to do."

Sim's first world title had arrived two years earlier on the home ground of Muju – and she admitted that having home advantage had been something of a mixed blessing.

"In Muju I was more nervous as it was my first try to win a World Championships," she said. "Many of the people in the crowd were from Korea and I knew some of them so that did make me feel more comfortable but I was still more nervous there.

"Here in Manchester, I felt some pressure as I didn't have the same support from the audience but I was very focused as I was trying to win to maximise qualification points for the Olympics.

"Obviously I would love to get gold at Tokyo 2020 but this is my first Olympics so really I just don't want to get nervous and to go out and do my best. 

"I am working hard to improve my physical skills because I am not the biggest in my category. I am smaller than the other athletes and so I tried to step a lot as I'm not as tall as other players."

Sim had to make her talent work in the under-49kg category throughout the rest of the year.

In June, at the World Taekwondo Grand Prix staged at the Foro Italico in Rome, she claimed a silver medal after losing 8-4 in her final against Russia's Elizaveta Ryadninskaya.

At the World Taekwondo Grand Prix in Chiba, as world champion Panipak Wongpattanakit of Thailand overcame China's double Olympic champion Jingyu Wu in the under-49kg class, Sim earned a bronze medal along with Tijana Bogdanovic of Serbia.

She missed out on the podium by one place in December last year at the World Taekwondo Grand Prix Final in Moscow, where she lost her contest at the Dynamo Sports Palace for the sole bronze on offer to Turkey's Rukiye Yildrim.

In April 2018, Sim injured her knee and was out for two months and avoiding a repeat injury is at the forefront of her mind. When fighting she can't feel the injury but she can when she trains a lot, and so she has to manage her schedule to give her the best chance in Tokyo.

"My first goal is to participate in the next Olympic Games," she said to World Taekwondo in Manchester. 

"I was focused on winning this final but I am also focused on avoiding getting injured. I got injured before and this was my first event this year and without injury I can keep performing."

Her medal collection at that point also included two golds, a silver and a bronze from the World Championships, as well as two golds from the Asian Games and one from the Asian Championships.

And yet, a few weeks after giving birth, Wu was lacing up her running shoes once again and starting on the long road back to elite competition.

After a two-year break she returned to competition last year as if she had never been away, adding further medals to her collection as she gathered momentum to make a fourth Olympic appearance at the Tokyo 2020 Games.

"Returning was difficult for me, as my body is not the same and I have to leave my baby at home," she told World Taekwondo after taking silver at the 2019 World Championships in Manchester. "But I want to break traditions and challenge my dream.

"I was determined to prove society wrong and come back strong. Women can have children and still do what they love and I want not only athletes, but women in society, to know that too."

Wu had reached the world final – where she lost 21-6 to Thailand's Rio 2016 bronze medallist Panipak Wongphattanakit – the hard way, having come through qualification.

She was overjoyed with her experience – and had the additional surprise of being awarded her medal by the President of the International Olympic Committee, Thomas Bach.

"It was an honour to be awarded my medal by President Thomas Bach," she told World Taekwondo in Manchester. "Before I competed at the Rio 2016 Olympic Games, he told me he would give me my medal.

"Unfortunately, I did not win at the Olympics and I was so disappointed. But it was a complete surprise to be awarded the medal by him [in Manchester].

"Every time I see President Bach, he inspires me to do better and has always encouraged me, which I really appreciate."

Upon her return to the sport earlier in 2019, Wu had demonstrated the effectiveness of her training as she won four tournaments leading up to the World Championships – the Fujairah Open, the WT President's Cup Asian section, the German Open and the Grand Slam qualification in Wuxi.

After her Manchester performance, she was soon back on the podium in the WT Grand Prix Series. After missing out in Rome she took silver in Chiba and then returned to the top of the podium in Sofia.

She followed up by taking two more prestigious silver medals at the Grand Prix final in Moscow and at the main Grand Slam event in Wuxi.

Her victor in Chiba and Wuxi was her Thai opponent in the world final.

In the Grand Prix Final, she was beaten by Serbia's Rio 2016 silver medallist Tijana Bogdanovic.

But the 33-year-old can look back on a year of huge achievement as she sets her sights on a fourth Olympic appearance.

"My family have supported me the whole way," she said. "I can't wait to get back to the Olympics and show women around the world that we are strong and can have a successful career and be a mother at the same time."

This 22-year-old operating at the top weight in women’s competition has been smiling a lot in recent years.

Two weeks before her 10-4 victory over Mexico’s Briseida Acosta in in the women’s over-63 kilograms final at the Foro Italica arena, Lee had earned world gold in the under-73kg category at the Manchester Arena.

Lee, who found competing in the under-73kg category easier as her opponents tended not to be as tall or powerful, said she was especially proud of her achievement in Rome given that she felt she had not had sufficient time to train since the World Championships in May.

She realises that operating in the heavyweight section of the women’s sport poses a unique challenge.

"At the next Grand Prix in Chiba there will be more powerful athletes who come so I want to do more weight training,” Lee said. 

"I want to train more for the physical side."

Lee, who took up the sport when she was at middle-school at the instigation of a friend, added: "I train in the morning for two hours and in the afternoon for another two hours. 

"When I practise taekwondo, I feel very happy. 

"Once a week I self-train after dinner. 

"When I am self-training it is just image training.”

A technique she dedicates a lot of time to in training is the head kick. 

"My favourite kick is the higher kick. 

"Especially when the body score is not so good like it was in Rome, I try more head kicks. 

"I am very good on short distance. 

"I am fast. 

"I try to make opponents keep guessing as I move quickly."

Meanwhile, Tokyo 2020 is firmly in her sights. 

"My first goal is to qualify," she said. 

"If I get it, I want to get a gold at Tokyo Olympics."

However, it was not just his accomplishments in the ring that stood out. Equally as impressive was his refreshingly laid back, humble and fun-loving personality that shone through throughout the tournament.

For many stars, the competitions attraction ends after the fight, but not for Lee, who stayed at the venue for pictures, handshakes and hugs with fans. It is his grounded demeanor that makes Lee, a three-time World Taekwondo Male Player of the Year, such a role model for the sport.

“I know many people are supporting me and I like to repay them with good results and being friendly,” Lee said.

“I think it is important to make fans feel happy because they are huge part of my motivation to win.”

Lee now has his sights firmly set on claiming an Olympic gold, a feat that he is still yet to achieve. However, he knows that there is a long list of Grand Prix’s to go before he has a chance to realize his dream at Tokyo 2020.

“Gold at Tokyo is my long-term goal, but I know that there are a lot of Grand Prix’s left before this. I just want to take it competition by competition, continue training hard, stay fit and focus on the next event.”

His likability, popularity, raw talent and strong desire to win make him the firm fan favorite. If he continues his incredible Grand Prix winning streak and keeps adding to his already impressive Olympic points tally then he will undoubtedly be in with a great chance of realizing Olympic glory.

Hossein Lotfi is one of a new batch of exciting young Iranian taekwondo fighters with a bright future ahead of him. Nicknamed ‘The Grasshopper’ because of his long reach with his front leg, Hossein won gold in the male -45kg category at the World Junior Championships this week in impressive fashion.

“I was confident in myself,” he said speaking 48 hours after winning his media. “I came to perform to the best of my abilities.”

He certainly did that, making full use of that trademark front leg to land a number of head kicks in the final and secure victory within two rounds after building a 20 point lead.

“I feel quite excellent. It is a reward for all the hard work that I have put into this,” he said.

But, he is not ready to rest on his laurels and is already focusing on improving and reaching new heights.

“All that is in my mind right now is just to train and work harder. In the long term it is a dream to join the senior team for 2020 Olympics. I know that I need to gain bodily strength and become stronger in order to properly compete at senior level.”

One of his heroes is two-time Olympic champion, Hadi Saei.

‘It is quite a challenge to pick one in Iran because we have a lot of taekwondo heroes in the country. However, personally I would have to say Hadi Saei. I know all of his fights by heart! I especially love the video in the 2004 Olympic final where he won gold with three seconds to spare.”

Hossein is on the right track and in Saei certainly has an inspirational athlete to look up to. If he can achieve half the success of his idol there is no doubt The Grasshopper will be jumping for joy.

In the male under-48 kilogram category, Jae-hee Mok of South Korea stalked onto the mats to contest gold with Saran Tangchatkaew of Thailand. Some junior matches are genteel, low-scoring affairs. What was about to transpire, however, was a real fight.

Right after the opening bell, Mok attacked and scored to the body, going one point up and igniting cheers from his teammates. The Thai shot back with a fierce series of body shots. The tempo rose. Both lads were firing kicks with real venom. At ringside, even the most jaded "seen-it-all, done-it-all" taekwondo masters and pundits had jerked awake and were following the action, blow-by-blow.

The Korean went two up, then appeared to land a face kick - but no score. His coach challenged; it was rewarded. Tangchatkaew fell twice and the round ended 6-0 to Mok. Round two was equally fast and furious with ax kicks, spinning back kicks and punches being unleashed by both fighters, but with no score from either.

In the third, Mok went up to nine points after firing a masterly body punch-head kick combo. In defence, his constant movement - he did not stand in one place for more than a second - and constant stream of attacks was making it impossible for the Thai to lock on his target radar. With the round only half over, Mok landed a picture-perfect ax kick to Tangchatkaew's face, ending the match 12-0 and taking the gold on point difference.

It had been a bravura display of taekwondo: fast-moving, hard-hitting and deadly accurate, enabled by Mok's technical excellence and empowered by his physical conditioning.

When you meet him, however, the 17-year-old from Songnam, Gyeonggi-do - the province surrounding South Korea's capital Seoul - is almost the complete opposite of his fighting persona. Shy, quiet and self-effacing, he left his coach, Kyung-bae Lee, to do most of the talking.

"It was the first time for me to fight these athletes," Mok said. "Me and my coach studied them a lot in the preliminaries and semi-finals."

"The Thai guy was really good at the ax kick," added Lee. "We studied him, and the idea was to avoid his ax kick."

What really lit up many ringside observers was Mok's body punch-high kick combination attacks. 

"It is my favorite technique," he said. Although the punch is the lowest-scoring attack in taekwondo - to the point where some competitors neglect it almost completely - it is a specialty of his school, Pungsaeng High School. "In our school, we use a lot of punches, we focus on exact punching skill," said Lee. "If the referees see it, they don't score it – but if they hear it, they score it."

Mok's technical excellence may be down to his long apprenticeship: he has been playing taekwondo since elementary school. As well as his punch-kick combination attacks, and a wide arsenal of kicks, he has superb lateral footwork. 

He also has an ideal physique - fast and light - which explains his agility and stamina. As the icing on the cake, he has sound tactical sense, which has enabled him to take out a string of taller athletes. 

"To fight a tall person, when they raise their opposite leg, you have to attack to beat them to the kick,”" Lee explained. "Taller athletes are slower." 

In the future, Mok knows what he wants to do. "I want to major in taekwondo at university," he said. "Everybody [parents and coach] has agreed. And I want to be a coach after competing."

Still, his chosen vocation means a tough, ascetic existence that few teens would be willing to tolerate. Under Lee's tutelage, after school, he trains seven days a week. "The only time off is Sunday mornings," Lee said.

As a result Mok, unlike his contemporaries, has no time to hang out at the mall or hit the karaoke room.

"I don’t have any hobbies," he said. "In my spare time, I just like resting at home."

The path to gold in the female -46kg category was not easy. Her final fight against Rim Bayaa of Sweden was one of the most exhausting taekwondo battles this correspondent has witnessed – proof positive that the formerly sickly child has achieved an awesome level of athleticism and stamina.

Both girls erupted straight into action from the opening bell, with the Thai dominating center court and the Swede attempting to score from the perimeter. Both were firing a wide range of techniques – ax kicks, crescent kicks, rear-leg round kicks – but it was the Thai who drew first blood with a razor-sharp chopping kick to the head that pole-axed the Swede to her knees for a 3-0 lead. Charanawat’s coach requested a video replay for a round kick to the head; it was denied. After an exchange of ax kicks in the clinch, the round ended 3-1 to Charanawat.

As round two got underway, Charanawat landed another head kick, going up 7-1. Action continued with the Thai trying to drop the ax and the Swede responding with spinning back kicks. Charanawat extended her lead to 10-1. More action followed with an exchange of punches, then the Swede landed to Charanawat’s head, bringing the board to 4-10. In the third, Bayaa went onto the attack, fighting forward strongly. The Thai’s flexibility was impressive to behold as she raised her ax kick toward the ceiling again, again and again; the board when to 5-11. As the round counted down, Charanawat – finally – seemed to be tiring, relying more on counter punches more than head kicks.

With 30 seconds left and the Swede 5-11 down, Bayaa had her work cut out and launched into all-out attack. But rather than retreating tactically and waiting for the clock to deliver her medal, Charanawat gamely fought back. In the dying seconds, both fighters tumbled to the floor. After a marathon of a match, Charanwat took gold 7-11, leaving Bayaa with a well-deserved silver.

In person, Mint – her nickname is a word-play from her sister’s name – is upbeat and bubbly, sporting a boyish bob and flashing an ever-present grin.

Going back to her start in combat sports she decided not to pursue Thailand’s native martial art – the fearsome Muay Thai kickboxing – instead choosing taekwondo to upgrade her health: “Muay Thai is too rough,” she said. “Some girls do it, but not many.”

Taekwondo led her to well-being, and she discovered a natural talent. As an athlete, she considers herself “very technical and very flexible.” Her favorite technique will surprise nobody who watched her match against Bayaa: “The ax kick off both legs,” she said. “And I try to make points with the punch.” But the key to her victory was staying focused in the moment. “I really wanted to be champ, I was very excited, but I had to calm down.”

She is not happy with the current state of the game. “I don’t like this side kick, push kick, side kick,” she said, “I can’t do it, I am too small.” Her fighting inspiration is Jordan’s jump-kicking Olympic gold medalist Ahmad Abughaush. “He moves fast and has good strategy,” she said.

In the future, she plans to transition to the adult division – and to study. “I want to go to the seniors, and I want to go to Tamarsard University to study advertising,” she said. Her ambitions are to be world champion in the seniors, then go on to the Olympics. After that, she would like to run a gym.

In conclusion, she thanked the Thai association who gave her the chance to attend Burnaby, the friends that she trains with, and her family. Speaking of which: How did Mint’s parents react to her world championship win? “I don’t know.” she laughed. “I called them, but because of the time difference between Canada and Thailand, they did not pick up."

On day two of the World Taekwondo Grand Prix Final in Baku, Iran’s Sajjad Mardani took out Rio silver medalist Abdoul Issoufou of Niger in a fiercely fought semi-final battle, 7-6. That victory thrust him into the final against Russia’s Vladislav Larin.

Game on. Mardani, looking stylish and catlike from the outset, scored with a punch almost immediately. Next, he unleashed a flurry of ax kicks which Larin covered well as both lads fought to control the centre of the ring. Larin raised an ax; Mardani stuffed it by moving in and body checking. The feeling-out round ended 1-0 to the Iranian.

In round two, Larin looked more aggressive, seizing a point with a check kick to the body that shook Mardani. Mardani shot back with a punch and crescent kick to the head, then a powerful round kick to the head and a serial attack that drove Larin backward. The Iranian fans started cheering, as Mardani grabbed another point to the body.

However, the point difference was minimal. In round three, the fight could still go either way. This tense dynamic was sensed by the audience: for the first time in the evening, the crowd started roaring.

Action resumed. Mardani tried punch-round kick combinations. Larin shot back. Mardani nodded in what looked like acknowledgment of his opponent’s attacks. In fact, he had worked out his opponent’s tempo and technique. "I knew than what I needed to do," he recalled. With one minute left on the clock, Mardani was 3-1 up. The Russian looked set to go into an all-out attack, but Mardani, unfazed, checked his offensive and picked up another point after Larin fell, raising his score to 4-1. Fifteen seconds remained as Mardani moved in close, leaving Larin no space to kick.

But there was still drama to be played out.

In the last three seconds Larin attacked, Mardani backpedaled out of the area and the Russian picked up a point to take the board up to 4-2. Just two seconds remained on the clock. An appeal by the Russian coach provided a break from the action. The Russian and Iranian supporters in the crowd roared. The appeal was rejected. The fighters replaced their mouth guards, buckled on their head protectors and stepped up to the mark. The last two seconds were in play.

Larin surged forward. Mardani counter-kicked and retreated. And that was that. The battle ended 4-3, with a gold medal for the man from Tehran.

After the Olympics, the Grand Prix Final medal earned by Mardani was not just a return to victorious form, but a potent injection of new confidence. "This proved that I could do my best and that my hard work had paid off," he said. "Now, I can hold my head high."

So what happened in Rio? The much-feared Iranian trio of Mardani and teammates Farzan Ashourzadeh Fallah and Mahdi Khodabakhshi had been taekwondo’s strongest, medal favorites. When the smoke cleared, all three were empty-handed.

Asked about the drubbing Iran’s men’s squad suffered - taekwondo pundits have been discussing ever since - Mardani went quiet. "It’s a tough one," he mused. "Let me think about it." After a while he composed himself. "For sure - 100 per cent. The athletes you expect to perform the best are the ones you study more and analyse," he said. "We were the favorites, so I believe people studied us."

The stress was particularly colossal for heavyweight Mardani who fought on the last day of the competition. "I was under a ton of pressure heading into my day as the two favourites [his two team mates] had been unsuccessful," he said. "That fact that I was unable to win as well was so painful. We were in disbelief."

Since then Mardani has been on an obsessive self-improvement drive. "You have to adjust and change and adapt - the person who remains the same is not successful in any sport," he said. "I have tried to focus on changing my game."

The Grand Prix Final gold suggests his efforts have borne fruit. "I have never seen Mardani look as good as he did in Baku," said an impressed Mike McKenzie, the WTF’s TV commentator.

Now 28, Mardani started taekwondo after seeing his mother and sister practice. "As soon as I saw taekwondo, I fell in love with it," he said. As a fighter, he reckons his strengths are his non-specialised approach to the game. "I believe I am well-rounded," he said. His favorite technique is the head attack, but he does not name any specific kick. "The leg goes from here to there," he said, gesturing from earth to sky.

Asked to name his favorite fighter, his response is telling. "I like Jade Jones," he said. "She believes in herself."

Unlike some of the Iranian athletes who live, eat and breathe taekwondo, taekwondo and only taekwondo, Mardani has a side job: fashion modeling.

That should surprise absolutely nobody. As well as boasting the height of the heavyweights and the toned physique of the pro athlete, Mardani is far and away the most wickedly handsome devil in the game. "I like modeling, I like being on billboards," he said. "I love it. One day I want to go out and be a full time model."

He thought for a second, then added: "And if I get the chance to be a model, it would be a great opportunity for taekwondo, too."

For now, his own goals focus on 2020 - though he is keeping his eyes on the near term. "Obviously, the goal is Tokyo, but I am focusing on day-by-day and only looking to the next competition," he said.  

Mardani’s focus on constant improvement suggests that he might be better advised to ditch modeling and become a motivational speaker.

"My goal is to show anyone around me that hard work pays off," he said. "I want to influence the people who surround me to always believe in themselves: it does not matter how difficult life becomes, you always want to achieve more - day by day you get smarter and stronger."

Despite his relative youth, Mardani is already thinking about his heritage. "Sajjad Mardani is a human like everybody else, but I have been blessed by God with so many things," he said. "The main thing is to make an impression, and to inspire others."

Armed with this attitude, Team Iran’s Rio experience may even prove to be a long-term positive. "In sport, one person wins, one person loses. We did not perform as well as we wanted, but that’s life," Mardani said. 

"We look forward to tomorrow."

The tall, attractive 27-year-old, who hails from Gangneung on Korea’s East Coast, "followed her friends from school" to taekwondo classes at age eight. Personal tragedy struck at age 10, when her father passed away. Since then, Oh and her two sisters - Hye-ri is the middle sister - were raised by their mother.

Taekwondo, however, remained a constant. Along with the camaraderie she found in the dojang, she discovered a talent and began competing at age 14. She did not consider her skills mature enough for Beijing in 2008, but did set her sights on the next Olympics. However, in the run up to London 2012, tragedy struck again.

Given the number of players in Korea, the qualification process is a grueling one, and in pre-training, Oh suffered a deeply torn quad. "My thigh swelled up like a balloon," she recalled. Even so, she appeared on the mats two weeks after the injury - to no avail. "I had no strength, and I could not get the right angle for the kicks," she said "I wanted to go to London, but I couldn’t." A saying in Korean states that "an Olympic medal is like a gift from god" and that gift seemed a long way off in the summer of 2012 as she watched the competition on television.

Fast forward to 2015. The next Olympic cycle was in full swing when Oh, now injury-free, captured gold at the World Championships in Chelyabinsk, Russia. That augured well for Rio 2016. And indeed, pacing onto the mats in Rio’s Carioca Arena, she was one step below the summit of the pinnacle of sports: Olympic gold. But to receive that "gift from god" Oh first had to defeat Team France’s formidable Haby "The Abigator" Niare.

In the women's under-67 kilogram category, Niare was the number one seed, Oh the number six; the Korean was also at a height disadvantage. In the first round, Niare - a fighter with tremendous flexibility - landed her trademark "scorpion kick", a heel hook kick fired from impossibly close range, to the back of Oh’s head, for a three-point lead. She extended it in the second, going 4-0 up. But Oh was undaunted, and returned fire with a spin back kick, taking the board to 4-3. Then, in a too-quick-to-follow flurry of kicks, the board flashed. 

Oh went into the attack and started pressuring the taller French fighter backward. In the third, both fighters tried to feint each other out before Niare appeared to land another scorpion kick - it registered but was disallowed. A video replay appeal failure. An ax kick attack bought Niare’s score back up, before Oh added another single point - then the action mingled fast-and-furious, close-and-mess. Both athletes went for broke with the scoreboard flashing points like a pinball game, and the referee working as hard as the fighters. The final result could have gone either way, but it ended with a tight 13-12 victory for Oh.

She does not remember much about the whirlwind fight that delivered her dream. "I was losing in the first round, but I was not nervous - I was concentrating so much I did not realise the score was that high," she said. "I don’t remember too much about it."

In a development that is typical of Oh’s up-and-down fortunes, the euphoria of Olympic gold wore off back home. "Koreans did not like the way their athletes fought in Rio," she said - a reference to the tactical "new school" approach they have adopted over the more flamboyant "old school" style. "But from the athletes’ perspective, we are fighting to win, we can’t just fight to make the game exciting and lose - it does not make any sense."

The brilliance of her achievement was also over-shadowed by the high expectations Koreans have of their taekwondo fighters. "Koreans say, 'if you are Korean, you have to get gold as it is our national sport', but I wish they would look at us in a kinder way, with warm eyes and a warm heart," she said. "If we get gold, they say, 'well, you should have!’ If we don’t, they say, 'what’s wrong with you?’”

Moreover, the success of Oh and taekwondo team mate and fellow gold winner So-hui Kim were overshadowed by the achievement of Sang-young Park, who won Korean a gold in fencing. "He became so famous that none of the other athletes could keep up with his popularity," she said. "Nobody recognises me." Remarkably, she has been offered no commercial sponsorships.

The post-Rio 2016 disappointment may have been blunted by her latest competitive triumph: gold at the Grand Prix Finals in Baku, Azerbaijan, the last major event on taekwondo’s 2016 fighting calendar. Injury free, she fought a highly professional match against veteran Chinese Taipei player Chia Chia Chuang. Although she characterises her fighting style as "shut up and attack" she took on Chuang with economical motion and sound tactics.

The Korean dominated from the start, gliding smoothly in and out, feinting with her arms and taking an early lead. That was soon reversed with Chuang going up 3-1. As usual, Oh showed her quality and in the third, went onto the attack, landing two head shots to go 7-3 up. It ended 8-4 to Oh, indicating that - following her triumph at the 2015 Worlds, the 2016 Olympics and the Grand Prix Finals - that she truly is at the top of her game.

In person, Oh is more talkative, relaxed and outgoing than some of the other Korean fighters - she displays an easy-going, natural charm. Her nickname hardly suits her athletic prowess, but does match her cheerful personality - "Duck". The nickname is a play on her given name. Oh Hye-ri sounds similar to the Korean word for duck - "ori". Despite her charm, she has no boyfriend and says, vaguely, that she would like to marry and have children after retirement. In her everyday life, she escapes the stresses of taekwondo training, relaxing by reading and taking long, midnight walks along the banks of Seoul’s Han River.

She is also a beginner in the sport which, perhaps more than any other, exemplifies solitude and freedom: surfing. "Right now, I have to do it with other beginners," she said. "But when I get better, I want to do it in places where there are not too many people around."

When travelling to competitions overseas, Oh studies English on the flights, which enables her to communicate with international players - all of whom she is on excellent terms with. On the way to this interview, she was stopped in the venue by Sweden’s Elin Johansson, who Oh had beaten the previous day, to exchange selfies.

She cites Turkey’s Servet "The Cheetah" Tazegul and Korea’s Dae-hoon Lee as the most inspirational fighters on the circuit. But, in a comment that perhaps reflects her own struggles, Oh says the players she most admires are those from developing nations like Ivory Coast - those who have to suffer and endure hardships in training.

And while her first reason to take up taekwondo was friendship, the reason she keeps doing it is not for gold-medal glory, but for the joy of the sport. "It is rare for anyone to have a career that she likes, but I love taekwondo," she said. "I am lucky."

Over a day of fighting that ended with her being crowned world champion in the female under-42 kilograms category, she scythed her way through the opposition, scoring 73 points and conceding none.

Yes, you read that right: none. Not one of her five opponents throughout the day managed to score a single point on the 15-year-old from Gilan, Iran.

"I think that must be a record," said WTF Technical Committee chairman Jung Kook-hyun. "I don't think anyone else has done that before." 

"I don’t know, I can't say," added Peter Bolz, curator of website www.taekwondodata.com. "But I think that is a record."

In person, Nejad Katesari does come across as an invincible fighting machine. Quietly spoken and with a shy but ready smile, she is small in stature and lacks the towering height of some current-generation competitors. But she moves with the obvious physical grace of the athlete and has the self-assurance of the chosen.

"Taekwondo is not about height, it is about techniques and about the mind," she said. "Strength and ability are important, but on top of that, it is about hard work and trying over and over again."

She started the game at the age of four, having seen bouts on TV. Already a third dan black belt, Nejad Katesari has added her first world junior title to her roster of wins, which include two cadet championship golds - at the worlds in Muju, Korea, and at the Asians in Taipei, Taiwan, both in 2015.

When it comes to offense, she is a master of the sliding ax kick and is fully ambidextrous. But what is her brilliant defence composed of? She puts it down to her ability with the push kick as a counter-attack weapon, but is unwilling to say any more. "It’s a secret," she said, mischievously.

Fatameh Safarpour, coach of the Iranian female junior team, is more forthcoming. "She is very smart and the key reason for her success in not giving any points away is that she can work with her knees very professionally - she brings up her knees - and she has a good push kick," Safarpour said. "She is very quick and her explosive movements and flexibility help her, so that the opponent cannot react to her - she is ahead of her opponents."

Her other weapon is her mind. "I have the power of making images of the game before I fight," she said. "This is what I learned from my coach."

She also has the intense discipline necessary to juggle schooling and the demands of elite taekwondo, for as a national team member, she has to attend the grueling three-month pre-competition training camps at Tehran's famous "Taekwondo House". 

"When I am not in camp, I go to school, and in the evenings I go to taekwondo practice sessions," she said.

"When I am in the camps I focus on taekwondo, and when I get back home, I get personal tutors to help me catch up with other students."

She is not happy with the current rule-set. "Since the single touch with the sole of the foot has come in, most of the athletes use it and taekwondo does not have any beauty any more as they don't use the more technical moves," she said.

However, she is positive about recent developments with the PSS. "I believe that the electronic headgear is very helpful as you are sure that the foot has impacted the headgear," she said. "In the traditional way, sometimes the referee might press the key without an impact." 

Given her recent string of victories, she is 100 per cent sure of what her life path should be. "I am going to major in taekwondo in university and take it as my occupation for life," she said. "I recently made that decision as, after I had achievements, I believed I could do this, it was motivating."

The decision to make taekwondo her life was completely her own, but her parents both encouraged and supported her, Nejad Katesari said. Naturally, they were "super happy" when she called them after her victory in Burnaby. 

As for influences in the sport, she cites her coach back home in Gilan, Neda Rastad. "She was my coach from the age of four," Nejad Katasari said. "She gives me positive energy and high spirits." Another is her taekwondo senior Kimia Alizadeh Zenoorin - who, in Rio, became the first Iranian female athlete ever to win an Olympic medal and has since won fame across Iran.

"I know her personally," she said. "She gave high motivation to all Iranian girls, so now they believe that if they try hard, they can have great achievements, like her."

In the future, destiny awaits. Nejad Katesari's ambitions are not lowly: she aims to be both an Olympic champion and a national team coach. "I am happy that as a Muslim girl my hijab did not create any limitations," she said. And of course, that destiny can build on the foundation of a very impressive recent record. "By winning 75 points in five games without losing any, I could make history," she said. 

The final buzzer rang on the bronze medal match in the women’s -57kg category and an 18-year-old athlete from Karaj, Iran, had done something that had never been done before: Kimia Alizadeh Zenoorin was the first female Iranian athlete to win an Olympic medal - not just in taekwondo, but in any discipline.

Taking on Sweden’s Nikita Glasnovic, the Iranian asserted her dominance early and extended it with a head kick that drew roars from the crowd. The Swede, despite firing off countless kicks, was unable to find the range and Alizadeh Zenoorin - after a final- seconds countdown from the crowd - won with rare conviction. She ended it by falling forward and kissing the field of play, then embracing her coach and taking photos with the crowd.

“I am very pleased to get this first medal -v ery pleased! - and very pleased for the girls of Iran,” said Alizadeh Zenoorin, speaking one day after her fight. “I had tears in my eyes from joy, but I also had a little thought: ‘I would love this to have been gold.’”

Even so, the colour of her medal is overshadowed by the enormity of her achievement.

“When I came here I wanted to break this enclosure, open the door, help other female athletes and also create a kind of self-confidence for people to go out there and do it,” she said.

In that sense, Rio is definitely “mission accomplished.”

On the personal front Alizadeh Zenoorin’s bronze medal victory is going to be a life-changing event, for she embodies the sportive empowerment of Iranian women. “Obviously, now my life is going to change in that I have to be a role model,” she mused. “It will be hard for me and my social life will change but I hope to be a good representative and a good person in society for people to follow.”

Her country has fully recognised the significance of what has happened. Iranian media are full of her pictures; her photo portrait has been emblazoned across a giant poster decorating a central Tehran overpass; actors and celebrities are lining up to congratulate her when she lands; there are even clips up on social media of inspired Iranian grandmothers performing zany taekwondo moves.

“Surely all the public in Iran are very pleased and happy to see my achievement,” she said “There is no restriction for female activities in [Iranian] sport and I hope from now on there will be lots of medals to follow.”

Her coach, Mahroo Komrani Najaf Abadi, reckons her protégé has kicked down the last barrier for female sport in Iran. “I want everybody to know that in Iran we all love and enjoy sport the same way men do, it is the same for women and men,” she said. “The only difference between rest of world and Iran is the boys train with male instructors and the girls train with female instructors.”

Alizadeh Zenoorin’s unexpected triumph - she was the Olympic tenth seed and her world ranking is 21st in a tough category that includes such high-profile stars a Team GB’s Jade Jones, Spain’s Eva Calvo Gomez and Egypt’s Hedaya Wahba - may mitigate the disaster that befell the Iranian men. Iran is a taekwondo superpower and the team it fielded in Rio was best-of-breed. But from day one, it all fell apart.

Farzan “The Tsunami” Ashourzadeh Fallah, the number-one seed and the favorite to win the -58kg went out in his very first match. Mahdi “The Terminator” Khobabakhshi was the number-one seed and the favorite to win the -80kg: he went out in his second match. Sajjad Mardani, the number-two seed and a strong medal possibility in the men +80kg also went down in his second fight. The Rio results indicate that the rest of the world has finally worked out how to beat the Iranian powerhouses.

Those matches must have been hard for Alizadeh Zenoorin to watch. And her own preparation for Rio was agonising. “Obviously, it was hard to come here and I had a lot of stress,” she said. “I lost 10 kilos to be ready for this competition” (Given that Alizadeh Zenoorin fights in the -57kg category, the extreme nature of that weight loss may be appreciated). Still, the reward has been worthwhile. “I worked hard to get a medal. I thank God for this opportunity and I hope to be a good role model,” she said.

At home, she is a student who, between classes and taekwondo sessions, enjoys hiking and climbing. In the future, she plans to finish her university degree in physiotherapy, become a physio, and teach taekwondo.

But given that she is aged just 18, there is more immediate business awaiting her on competition mats worldwide.

“She is very clever, she has a lot of patience and she is also, in my opinion, one of the best players in the world in taekwondo,” said her coach, Mahroo Komrani Najaf Abadi. “Kimia has beaten [Rio gold medalist] Jade Jones twice. (Indeed, on the sidelines of the competition mats, one taekwondo pundit opined that it was fortunate for Great Britain that the team’s golden athlete was not drawn against Alizadeh Zenoorin in the preliminaries).

“I would love to have faced her in the finals, I have competed against her four times and beaten her twice,” Alizadeh Zenoorin added. “A lot of people in my weight I have competed against and beaten, I have beaten others before who are here - but unfortunately, I could not do it this time.”

She cites Iranian taekwondo legend Hadi Saei, Team Korea bronze medalist Dae-hoon Lee and Team China double Olympic gold medalist Jingyu Wu as her inspirations in the sport. With her height - she is a good head taller than Jones - and her weaponry - her round kick to the body is a consistent scoring technique - she has all the right physical qualities to win more medals.

“When I arrive in Iran, I want to rest to heal my injuries, then work hard to change the colour of the medal I have now,” she said.

“I took taekwondo up when I was nine as I was very weak and ill - I took it up for my health,” said Kim. “My parents suggested starting it, and now I am all good.”

“All good” is an understatement: Kim has today cast off her weakling status and has transformed into an elite athlete competing and winning at the highest level of taekwondo. The 22-year old, who grew up in the countryside in Chuncheon before migrating to Seoul for high school, captured the ultimate medal in sport at the Carioca Arena 3 in Rio’s Barra Olympic Park, when she won gold in the women’s -49kg category.

But it was no easy match.

Kim, the seventh seed in the women’s -49kg category, would be fighting against eighth-seeded Tijana Bogdanovic who had the height (and probably strength) advantage. Earlier in the day, the Serbian had stunned the taekwondo world by comprehensively defeating arguably the most dominant fighter in the sport, China’s double Olympic gold medalist Jingyu Wu, 17-7; Wu had been gunning for what would have been a record third Olympic taekwondo gold. “I was not nervous to face Bogdanovic, I was worried about Wu,” said Kim. “I expected to fight with Wu at the final, I had prepared a lot for Wu.”

The fact that Bogdanovic had ejected Wu made very clear that Kim was facing a well-prepared, top-drawer opponent.

From the outset, the Serbian, with her height advantage, fought forward, forcing Kim to dance around the edge of the mats. But it was the Korean who was more accurate with her legs, winning the first round 2-1. The second continued the same way, with Kim displaying lively footwork to escape the Serbian’s attack. Bogdanovic, trying to land a punch, took a crescent kick to the head; the round ended 5-2. In the third, the score was 6-4 to the Korean but Bogdanovic put the pressure on, and Kim visited the mats repeatedly. In the last 11 seconds, Bogdanovic was chasing her target around the field of play but Kim held off the desperate last-minute attack, taking the match and gold medal, 7-6.

After the match she said she had “prayed to become a champion” and gave thanks to her family and nation for the support she had received.

Although it had been a close-run thing - Kim’s fall just as the final buzzer rang could have cost her the match - the fight had gone according to plan. “The Serbian girl is good at face kicks so I was concerned about that,” Kim said. “I thought that if I could beat her face kick, it would break her mentality. The back step and footwork was the plan.”

Oddly, the manner of her victory came in for a fair amount of online criticism in Korea, with some critiquing her style and strategy. In fact, Kim’s evasive, counter-attacking game plan showcased true mastery of lateral footwork and fighting off of the back leg - which causes one to question the technical knowledge of her armchair critics.

Olympic gold is just the latest in the fourth-dan’s list of accomplishments, which include gold at the 2015 Grand Prix tournament in Moscow, and gold in the -46kg category at the 2013 World Championships in Puebla, Mexico. As a taekwondo fighter she reels of her list of advantages. “Moving fast, I play a timing game and strike at the right time,” she said. “I like the back kick best of all - it is a special kick and I can fire it from both legs.”

Expect to see more of Kim in the future: Given her tender age, she has a long fighting career stretching ahead of her. “I always challenge the next one,” she said. “I want to go to Tokyo 2020 if possible.”

The people who got their formerly sickly daughter into the sport were at ringside for her triumph. “My parents were in Rio, and they were in tears, especially my mom,” she said.

But what about her own emotions? How did it feel to capture the ultimate prize?

“I’d always dreamt of being an Olympic gold medalist,” she said. “I realised the dream.”

Although he was sidelined by injury and did not make the recent Mexico City Grand Prix Final, the Iranian has won his nation a spot in Rio 2016 with flying colors. He is the number-one ranked player in the men’s under 80kg division - arguably, the fiercest competitive category in the game. He is the current world champion, the 2014 Asian Games champion and holds three Grand Prix gold medals.

His nickname is “The Terminator” but his surname may be even more appropriate to his phenomenal talent:  in Farsi, “Khodabakhshi” means “God Given.”

If that talent was granted by God, it was incubated by his father. The 24-year-old started taekwondo under the tutelage of Khodabakhshi Sr. at the age of four - or, as he puts it himself, “since I grew arms and legs!”  It was no easy regimen: “I did not like taekwondo, but my father forced me to do it,” he said. “My whole family practice; my sister is an instructor; my uncles are instructors.”

Now a fourth dan, he has been a staple on the formidable Iranian men’s team for four years and may well be its most valuable property.

The match which planted him firmly on the map was his battle against Aaron Cook in the Manchester Grand Prix Final in 2013. At the time Cook, then fighting for the Isle of Man, was both the number one in the category and a massive and perennial crowd favorite. “It was very interesting, my first time to fight Aaron,” Khodabakhshi recalled. “The whole audience was behind Aaron, and that made me even more motivated to win.”

The Iranian picked off points for an early lead. Cook, however, never says die, and in the third round he surged out like a typhoon, lunging across the mats in a barrage of no-holds-barred assaults, launching combination round kicks and spin kicks. The Iranian kept his cool and fought to keep Cook at distance. “I needed very single point I could get,” Khodabakhshi said. “It was one of the best fights ever.” The final score: 13-11 to the Iranian.

If there is a perfect physique for taekwondo, Khodabakhshi owns it. He is tall, lean and long-limbed.

Although he possesses a weapons-grade front leg, his favourite technique is the jump spinning round kick, unleashed against either body or face. Fighting from a wide, side-on stance, using his hands to feint and employing a dance-like torso movement, he looks confident, dangerous and stylish.

Naturally, he is a crowd pleaser. “I want my audience to enjoy my games,” he said, “But my movement is not intentional - when I watch myself I think, ‘What the hell was I doing?’ I have no idea!”

He credits rigorous training for the development of his killer front leg: “I believe my legs and my backside are my strengths,” he said. “Because of the new system, we have to work hard on front-leg kicks, and that has made my legs very strong.”

The modern game, however, requires more than just physical attributes. “I am very analytical,” he said. “Every person I am going to fight, I analyse.”

But nobody is indestructible - a lesson Khodabakhshi learned in October.  A firm favorite for gold at the 2015 Manchester Grand Prix Series 3, he went onto the mats against Britain's Lutalo Muhammad in the quarter-finals.  The audience, excited to see “The Terminator” take on the home-town boy, went quiet after Khodabakhshi lurched. Clearly, something bad had happened. The Iranian struggled - against obvious agony - to continue, before the fight was halted: He had suffered a severe angle sprain.

Recovery has been slow. In order to make the weight for the GP Series 2 in Samsun, Turkey and Series 3 in Manchester, UK, “I got weaker and lowered my immune system,” Khodabakhshi said. That explains his very conspicuous absence from the Grand Prix Final in Mexico City. However, he expects to be back to full fighting fitness by the year-end.

His success on the mats in the 2014 and 2015 seasons - not to mention his reputation as the man to beat - indicate that his conditioning, technique, tactics and training are best-of-breed. But in the months leading up to the Rio Olympics, he plans to radically overhaul his game. “I believe that I am being watched and analysed by other players, and I don’t want them to read my hand,” he said. “I am going to show you a different Mahdi there.”

The lithe moves and athletic physique that make him so dangerous on the fighting circuit, combined with his good looks, also make him dangerous with the ladies. Asked if he has a girl friend he joked, “About a thousand!” Then he quickly corrected himself. “I don’t break hearts!” he insisted. “If anyone likes me - send me a message!”

When not engaged in the gruelling training programme of the Iranian taekwondo athletes, he enjoys volleyball and travel. Taekwondo has provided a passport to the world. Spain has been his favorite destination thus far. He also likes cars. He drives a Hyundai, but hopes to own a Maserati. Is that feasible on his current salary as an athlete? “No!” he says - but it may be, “… in a few years, when I have managed to make money out of my titles.”

As a child, he hated taekwondo. Now as a man, he finds it compelling. “Although I was forced to start taekwondo from a young age, as I got older, I learned more about the art,” he said. “The more it became a profession for me, the more I found it interesting.”

Even so, “The Terminator” may hang up his dobok after the 2016 Games.

“I plan to get a gold in the Olympics – I will deliver my best-ever performance! - and then I am not sure if I want to carry on,” he said. “I am under a lot of pressure and stress which affects my personal life. I want to have some sort of calm.”

After what happened in Manchester, there will no more pressure from his taekwondo-centric family.

“My family is very proud and happy as I am successful, but they care about my well-being more than my achievements in taekwondo,” he said. “Since I got injured, they have given up on forcing me to do taekwondo after Rio.”

One of the most notable trends in WTF taekwondo in recent years has been the rise and rise of new taekwondo superpowers. Iran, for example, boasts a fearsome array of champions and potential champions in the sport, while Russia, leveraging its long-standing tradition of athletic excellence, is storming forward in the rankings.

These challenges mean that the customary dominance of Korea - from whence taekwondo originates - is under extreme pressure. But don’t tell that to Lee Dae-hoon.

Garnering 30 votes out of 105 cast among his peers, the 22-year-old Seoul native was voted the WTF Male Player of the Year at the inaugural WTF Gala Awards Dinner in Queretaro, Mexico on December 5 last year. Why so?

“Because of my poor English, I don’t have many foreign friends and I did not even think I could be the recipient,” he said. “But my active, dynamic way of fighting - rather than a dull one - may have helped me win the honour.”

Fighting in one of the most competitive weight categories in the sport, Lee has a crowd-pleasing style: “One of my specialties is kicking to the head!” he said.

Given current rules that favor the front cut kick or push kick to the PSS, high kicks are high-risk. As a result, Lee is modifying his game: “Nowadays I practice to kick to the body as my opponents know my tactics,” he said. “I practice hard according to changed WTF Competition Rules.”

Lee’s competitive record is a glittering roster of wins and near misses.

He was the gold-medal winner in the under 63kg category at the Asian Games in Guangzhou, China in 2010; gold medalist in the same category at the 2011 World Taekwondo Championships in Gyeongju, Korea. He took silver in the under 58kg category at the 2012 London Olympic Games; and won gold in the under 63kg category at the 2013 World Taekwondo Championships in Puebla, Mexico.

Although success eluded him in Queretaro, he is a two-time winner of five Grand Prix events - taking home gold in the -68 kg category in Suzhou, China and in Manchester, Britain.

Currently, Lee trains a sweat-generating seven hours per day except weekends, and benefits from highly professional preparation.

But preparation and training is no longer a guarantee of success, given that the competition from non-Korean fighters is stiffer than ever. “It is a fact that Korea wins less medals at taekwondo events nowadays than before,” he said. “But we manage to do well.”

And while that may not please die-hard Korean taekwondo fans, it is good for the sport overall, Lee reckons. “A certain country’s monopoly of medals is not desirable,” he mused. “I think we need more analysis of foreign players to produce good results.” Indeed, Lee’s favorite player in the sport right now is not a team-mate, but Spain’s Gomez Gonzalez.

Even so, being born Korean does confer some advantages. Lee kicked off this taekwondo career at a gym in Sinchon, Seoul at the tender age of four under the watchful eye of his coach - who also happens to be his father. Both he and his brother now wear fourth-dan black belts.

But taekwondo is ever-changing. Asked how the protector and scoring system (PSS) is affecting the sport, he was more diplomatic than some players, who complain that the gear is encouraging the use of less-spectacular front-foot kicks to the body, rather than turning or spinning kicks to the head.

“The use of PSS has made taekwondo competitions fairer and more transparent: both players are fighting under the same conditions,” Lee opined. “The adoption of PSS has inevitably resulted in the change in the fighting style of players. Players have become clever and more thoughtful.”

And he is hoping that his style will continue to win him fans among his peers. “I want to be selected as the WTF Male Player of the Year 2015,” he said.

Wu made her global debut at the 2007 World Championships in Beijing, when at the age of only 20, she grabbed gold with a combination of exclusive technique and dynamic power that few could imitate. That win propelled her to the forefront of international taekwondo and led to predictions of Olympic medals. She fulfilled those expectations in the same city the following year.

Wu admits to harboring dreams - but is also prepared to fight to achieve them. Her 13 years of training defines her persistence. Now, she dreams of competing in three Olympiads in a row, like her compatriot, Chen Zhong, winner of Olympic gold at Sydney 2000 and Athens 2004 - and, more than that, to clinch three titles. As the taekwondo player to win consecutive Olympic titles, Chen was Wu's bench- mark.

"We were fighting together in the Beijing 2008 Olympics, which was her third successive Olympics," Wu said. "I learnt a lot from her, I felt her power of never giving up, and that is the power that pushes me to pursue my dreams."

Training is tough, but Wu, to coin a Chinese phrase, "eats bitterness" with laughter. "It's like practicing Buddhism: You have to stay calm, ignore all disturbances and taste the bitterness as sugar,"she said. "Then, when you are looking back, all the tough experiences will become great memories and will be definitely worth everything."

Yet there was no guarantee that Wu would achieve her dreams, for between 2008 and 2012, taekwondo was in a state of flux. New competition rules and PSS changed the game. More speed, more combinations and more aggression were the new keys to victory. Would Wu be able to adapt to this scenario and defend her title in London?

On August 8, 2012, in the ExCel London Arena, Wu set foot on the champions' podium in the women's under 49kg category for the second time. She remembers the great joy of the moment. "What is happiness?" she asked. "To me, happiness is that I can persist in whatever I like, and I can persist in pursuing my dreams. If one more kick will take me one step closer to my dreams, why should I stop? My body may feel exhausted, but my heart is delighted."

Today, Wu, an Olympic taekwondo heroine, is sharing her dream and inspiring the young generation in China, where she has been invited to schools and universities to share her story.

"Youngsters nowadays meet with few setbacks when they are growing up, so may not have courage and resolution when facing troubles," she mused. "I hope they can be stronger, not only physically but more mentally. I would like to share my experience with them so they can learn that there will be no success if you are only waiting, instead of fighting."

Wu, therefore, felt greatly honoured when she was asked to play a leading role in the preparations for the Summer Youth Olympic Games held in Nanjing in 2014. She felt a strong sense of calling to help youth from different cultures get together to communicate and interact with each other. Her mission began on the occasion of the Nanjing 2014 Youth Olympic Games Culture Festival and the unveiling of the event's official mascot.

Today, Wu is ensuring that she has the right skills to do what she feels compelled to do: In between kicking practice, she is enrolled in higher education.

"I'm now continuing my college education in Suzhou University and my major is English," she said. "Language is the most effective way to exchange your opinions with others. With proper communication, I can learn more from athletes and coaches from other coun- tries. This is a great opportunity to me, and I can help young people in China to be more independent, more confident and more inclusive in their way of pursuing dreams."

Wu won a bronze medal at the 2014 Asian Games in Incheon but her sights are set on bigger goals. Rio 2016 is getting closer and she can hear it calling. 

Her team-mate Cheick Sallah Cissé earned the Olympic title in the men's 80 kilograms class at Rio 2016 thanks to a final second kick to the head in his final against Britain's Lutalo Muhummad.

On the same evening Gbagbi won women's Olympic 67kg bronze as she defeated Azerbaijan's Farida Azizova.

Gbagbi then contributed her own global gold to Africa in general, and Ivory Coast in particular, as she won the world title the following year in Muju in South Korea.

As she sets her sights on another Olympic podium, close observers of the sport are still recalling her startling victory over Britain's 20-year-old double European champion Lauren Williams in the final of the Sofia Grand Prix.

At 5-0 down in round one to an opponent who has the reputation as being the fiercest fighter in the women's 67kg class, Gbagbi gave extraordinary proof of the instinctive nature of her talent as she levelled the score with one extraordinary, indeed unique, kick.

Forced back to the edge of the mats, the Ivorian fighter unleashed a "jump reverse turning kick". 

Both feet were off the mats, and her kicking leg was higher than her head as her heel connected to Williams' head protector.

With the score at 5-5, Gbagbi was right back in it, and she made good her advantage to earn hard-won gold by a final score of 25-20.

"She is very powerful and very creative," Philippe Bouedo, a hugely experienced taekwondo fighter, coach and official who will be World Taekwondo's technical delegate at the Tokyo 2020 Olympics, said.

"She has a full palette of techniques."

Gbagbi, meanwhile, insisted: "It was instinctive! I did not have a plan about that.

"When the action came, I reacted in that way. I did not really practice it."

Having taken up the sport 16-years-ago, following the lead of a cousin, Gbagbi has also earned victories in the 2017 Moscow Grand Prix and the 2017 Wuxi Grand Slam.

"I am a fighter," she said. "The more difficult it is, the more I like it!"

Bouedo added: "She is the perfect aspect of taekwondo – we want to show people how exciting the game is.

"In championships, some players minimise risk, but not Gbagbi. She has no limits." 

When he marched into the stadium as his nation’s standard bearer during the Olympic Opening ceremony, bare-breasted, muscular and glistening, women around the world swooned, men invested in gym memberships and body oil and the Internet went wild, making the Tongan taekwondo fighter the first (and arguably the biggest) viral hit of Rio 2016.

What does he make of his overnight success?

“It was not overnight!,” said the smiling 32-year-old who, though of Tongan birth, lives and works in Brisbane, Australia. “This was 20 years of taekwondo discipline to get me to this point! This point was just the tip of the iceberg!”

Even so, the constant stream of media attention has been a surprise.

“We thought, ‘Oh, it will settle down and I will have time to focus on training,’ but it just got bigger!,” he said during an interview with WTF Communications in the athlete warm-up area of Carioca Arena 3, in Rio’s Barra Olympic Park. “We have had media from all over the world: From Argentina, Brazil, Korea, China, Australia, America….”

Indeed. During and after the Opening Ceremony, there were 45 million hits on Google asking “Where is Tonga?” and “What Sport Does Taufatofua Do?” He has since been featured in the Washington Post, TIME magazine, Entertainment Weekly, the Wall Street Journal and a host of other media that are virgin territory for taekwondo fighters. Some 100 million viewers tuned in during his appearance on “The Today Show,” and George Bush’s daughter was filmed oiling him up. (“Who’s the superpower now?,” he jokes) Finally, his (again, topless) appearance at the Olympic Closing Ceremony generated a second wave of hysteria.

In short, he has been given an opportunity - and it is one that he intends to take full advantage of. “It is important for me to get Tonga out to the world,” he said. “And to get taekwondo out to the world, as well.” In fact, his nickname is “The Real Tongan Ninja.” “There was an old movie called ‘The Tongan Ninja,’” he explained. “So people started to say, ‘We need to call him, The Real Tongan Ninja.’”

While he is understandably reluctant to discuss any of the commercial sponsorship opportunities that have suddenly become available, he knows that the money could be a game changer for his cash-strapped region. “We have been self-funded for years,” he said. “It has been tough, a very tough time for us.”

His Olympic baptism of fire was tough, too, as his +80kg fight pitted him against Iranian top gun Sajjad Mardani. It proved a one-sided war. While Taufatofua was game, and showcased a wide range of techniques, Mardani delivered a stern lesson, taking the match 16-1.

“I did not realise how quick his front leg was - I did not think it would reach me, my distance was off,” the Tongan mused, post-fight. “But we fought, we shook hands, we gave the crowd a show and the crowd was happy - at my expense!

“That is the taekwondo we have to take to the world!”

The experience gulf between Mardani, a frequent fixture on the international circuit and world ranked number three, and Taufatofua, world ranked number 157, was as wide as the geographical gulf between Iran and the Pacific Island nation: It was only the Tongan’s third fight in three years.

“I have not fought anyone on that level that I can remember, I don’t have world ranking points as I could not afford to go to the European Opens or the Grand Prix,” he said. “But I feel I have enough tools if I could grow them. And we have shown the world that Tonga is a small nation, but big-hearted.”

The commercial opportunities which his sudden fame have generated could help transform the underfunded state of Oceania taekwondo - which failed to win any medals in Rio. “We can really bring up the next generation of athletes and get funding for the Pacific, this is a big thing for us,” he said. “We are a small country, but now we have a big voice.”

And it is an educated voice - Taufatofua is no muscle head. Professionally, he is a counsellor for homeless youth, a job in which his strong Christian faith and his taekwondo training - training he has been engaged in since he was five years old - provide a powerful foundation. “I use the discipline of taekwondo to help people,” he said. “I work full time, I train full time and I study full time.”

Even so, as the new poster athlete for taekwondo as a form of physical conditioning, he has strong views on health and fitness, insisting that functional strength is more important than aesthetic looks.

His power workout consists of plyometric routines, kettlebell routines, functional weight training and cable/pulley exercises. For cardio, he does wind sprints on the incline treadmill: 10-15 second sprints, then 30 seconds break. And for flexibility, he stretches twice a day, both the front and rear lines of the body.

Where does taekwondo slot into the fitness matrix? “Martial arts is fundamental, it offers a couple of things which normal bodybuilding does not,” he said. “It changes your mind as well as your body; it makes you stronger mentally, then your body follows.”

The chief reason people fail to attain physical fitness, he believes, is their inability to persevere. “People give up way too easily, they look for the quick-and-easy method,” he opined. “The reality is that you have to go through the valley to reach the mountain.”

Another problem is the temptations of modern life. “I feel men give up a little bit too early,” he said. “They are at this point where it is too hard, it is easier to eat crap food and drink crap drinks.”

The results of “The Real Tongan Ninja’s” dedication are built into the physique he showcased to the world, drenched in baby oil. “Not baby oil,” he insisted. “Coconut oil!”

So what made him decide to go out bare-breasted, instead of in a conventional blazer and slacks?

Was it male pride? Or perhaps the egotism of the elite athlete?

He turns serious. “As opposed to the Western influence, the blazer, we wanted to go out wearing what our ancestors wore into battle 200 years ago,” he said.

Spoken like a warrior.

Aged 36, he had won three world titles in the under-61 kilograms K43 division, two European titles and an International Wheelchair and Amputee Sports Federation World Games championship.

"My goal in 2018 is to win every tournament I compete in," he told World Taekwondo. "And I want to compete in them all."

This is exactly what he did – the highlight being a 29-22 victory over rising Japanese talent Kenta Awatari to claim the Pan American Championships title.

Forced to switch from boxing to Para-taekwondo after losing his hands in an accident with a home-made bomb at the age of 18, Kong turned to martial arts philosophy to help cope with the loss.

"Martial arts develops your self esteem," he said.

"It develops a respect for the world in you, a sense of community, and a feeling of empathy."

Having earned gold at the first Para Taekwondo World Championships, Kong is determined to win again as Para-taekwondo makes its Olympic debut in Tokyo.

"The one that wins is the best of the best," he said. "This achievement is my dream – to be the best in the world."

That towering ambition, of course, is now on hold to 2021 in the wake of the COVID-19 pandemic.

Kong was among a group of the world's leading Para-taekwondo athletes who demonstrated how they coped with the restrictive measures put in place due to cornoavirus.

The video was the first of World Taekwondo's online "Kicking It At Home" campaign and included footage of Kong – who was born in Vietnam but came to France aged three – at home. 

Other notable Para-taekwondo athletes involved included Gamze Gurdal of Turkey, Peru's Angelica Espinoza, Lisa Gjessing of Denmark, Mexican Juan Diego Garcia Lopez, Veena Arora of India, Brazil's Nathan Torquato, Alejandro Vidal Alvarez of Spain and Italy's Antonio Bossolo.

When the lockdown halted competition, Kong could reflect on another highly successful season in 2019.

He made the podium at the one-day Tokyo 2020 test event in Chiba on September 28, fighting in the only men's competition, the K44 under-61kg category.

Bolorerdene Ganbat of Mongolia was the victor in the men's event, defeating Antonino Bossolo of Italy 16-12 in the final.

Kong completed the podium along with Mitsuya Tanaka of Japan, winning bronze.

On June 16, Kong won his 11th consecutive tournament in the men's under-61kg K43 class as he took another Pan Am Open title in Portland.

In his previous tournament, Kong had successfully defended his world title at the Championships held in Antalya, Turkey, in February – although he had been made to work hard in the final before beating Israel's Asaf Yasur 24-22.

Kong is a phenomenon – and Tokyo remains in his sights…

A high, round kick to the head of Morocco's Nada Laraaj turned a 3-2 deficit into a 4-3 winning margin for the 26-year-old Turkish fighter whose career was gathering huge momentum up to the point where competition had to be held up because of the 2020 coronavirus pandemic.

"One second," said the leggy, five foot, nine inch fighter in an interview the following day with World Taekwondo. 

"I can't believe it, but at that moment I was hearing the signal and I was so happy."

Iİlgün started taekwondo 14-years-ago though a family contact. 

"My advantages are that my legs are very long, and I am strong and slim," she said. "And I work hard."

Her promise in the sport was soon evident as she earned second place in the senior under-49kg event at the Dutch Open aged 16. The following year, she was under-57kg bronze medallist at the European Under-21 Championships in Chisinau and senior titles soon followed in the Turkish, Ukraine and Moldova Open events.

In 2017, she took another significant step-up as she won under-57kg silver at the World Championships in Muju, losing 7-5 to South Korea's Lee Ah-reum, who had beaten Britain's Olympic champion Jade Jones in the semi-final.

Before the year was over she had won gold at the Summer Universiade in Taipei, and she followed up by earning her first Grand Prix title in Rabat. 

At the 2018 European Championships in Kazan she added another significant medal to her collection as she earned silver, losing to Jones in the final.

In 2019, she produced a series of results that bettered for consistency anything she had done before. 

Her Chiba win was preceded by silver at the Rome Grand Prix, and followed by bronze at the Sofia Grand Prix and a silver in the Grand Prix Final in Moscow.

She continued into 2020 in the same dominant vein, winning the Fujairah Open and WT Presidents Cup - Europe in Helsingborg before taking bronze at the German Open.

Qualification for the next Olympics has been amply secured.

"I am really hard working," she told World Taekwondo. "And I really want to be there."

A medal at Tokyo would be a life-changing achievement. Turkey awards successful European, World or Olympic medal-winning athletes with monetary compensation and post-career coaching positions.

"That is good for building my future," she added. "But I will fight under the Turkish national flag. That is more important to me than money."

This 23-year-old from Plaistow in East London, who switched from kickboxing – his father’s sport – to taekwondo in 2013 – has shown ample talent and versatility since, and his performance in earning silver at the World Taekwondo (WT) Grand Prix in Chiba last October only confirmed his growing presence in the sport.

"I was from kickboxing, which is the same sort of thing [to taekwondo]," he told World Taekwondo. 

"The transition from one combat sport to another was not a great challenge. My persona is I adapt well, I am good at learning."

Since working with Team GB's coaching and conditioning staff in Manchester, McNeish has established an estimable CV.

In 2014 he indicated his huge potential in his new discipline by winning bronze in the under-63kg category at the Youth Olympics in Nanjing.

The following year he won bronze in the under-68kg class at the Summer Universiade in Gwangju, South Korea.

He has since earned further success at senior level. His stand-out achievement from 2017 was a bronze medal in the Moscow Grand Prix, where he was narrowly beaten 17-16 in his semi-final by home athlete Alexey Denisenko.

In the next competition after that, the London Grand Prix, the rivalry between himself and Sinden was pointed-up as the younger man beat him 18-17.

The following year he became European champion in the Russian city of Kazan with a 28-21 win over home athlete Sarmat Tcakoev.

There was disappointment for McNeish last year as he lost his opening contest at the Manchester World Championships in May. But his form picked up dramatically with five medals, before competition was suspended due to the coronavirus outbreak.

He won the World Taekwondo President's Cup – Oceania, held in Carrara, Queensland, and then stepped briefly up to the under-74kg class in winning bronze at the Australian Open.

Moving on to the Grand Prix at Chiba, he produced one of his most impressive performances, although he had to settle eventually for silver after a hugely competitive final against Iran's Mirhashem Hosseini who won 36-20.

"I am happy with how the day went," he told World Taekwondo in the aftermath.

"I had some good fights, and I improved over my previous performance at GPs and at the Worlds.

"I am definitely happy with how it has gone and I hope to continue to improve on my performance."

In December, at the final Grand Prix of 2019 in Wuxi, McNeish also excelled, only missing out on bronze after losing 2-1 to home competitor Lin Wenye on golden point.

This year has offered him two further material rewards for his talent in the shape of a bronze medal from the WT President's Cup – Europe, held in Helsingborg, and gold in the Hamburg Open.

Asked to assess his own style, he said: "Obviously leg control – but my favourites are any things that are a bit more erratic and dynamic." 

On the technique front, his favoured blows are all crowd-pleasers: back kicks, double kicks and – something that was very much on show during his Chiba final – high kicks delivered from within the clinch.

Clearly he is at home in both open play and the close-in ruck. "I try to be balanced," he said.

He has also prioritised stamina. "I push my fitness, so I can push the fight," he said, which explains the extraordinary work rate that was apparent in his Chiba bouts.

Above all, he is a self-believer. "I rate myself as a fighter and I don't over-rate other fighters," he said. "My dad calls me 'champion.'"

No wonder this 24-year-old from Nancy in France is heading towards the Tokyo Olympics – and indeed the Paris 2024 Games – with ever-increasing confidence.

At 5ft, 8in Wiet Henin is not particularly tall for her welterweight category. But she has on her side a natural agility and strong mental approach. And, also, the benefit of having two parents who were top class boxers.

"My parents were both world champions, though they are retired now," Wiet Henin told World Taekwondo in September 2019 after winning the under-67 kilograms gold at the Chiba Grand Prix.

"They never wanted me to do boxing – too rough! Taekwondo is more about strategy and spinning kicks; it is not as rough as boxing."

That Chiba win against her 6ft opponent, Matea Jelic of Croatia, offered evidence of all the strengths this determined competitor now carries having begun her taekwondo career at the age of six.

While her more powerful opponent dominated at the centre of the mat, Wiet Henin danced around the perimeter and, after going into the third round at 4-4, earned a 5-4 win with a single, powerful punch.

Her modest height for her category requires a clear strategy, and there was a detailed plan for her final against Jelic. "My coach said that, because she is bigger, I have to do no-risk actions, control the match and engage only when I was 100 per cent sure," she said.

"The fighters I have to fight are taller, so I have to control the fight with the front leg, and I have developed an explosive cut kick and follow up."

She has some advice for anyone taking on bigger opponents.

"Don't be scared!" she said. "Their size does not mean they will win, it means you have to use other weapons. 

"Their weapon is size – we have a lot of different weapons."

In terms of her own strengths, Wiet Henin mentions speed, precision and conditioning. 

"I can go three rounds and keep going, going and going," she said. But, when asked to reveal her endurance routine, she countered with: "That's a secret!"

She added: "We prepare for every match, so when I come, I know how to get ready in my head."

Wiet Henin uses mental focus and breathing exercises to suppress the pre-fight jitters. "I am not stressed – I know how to manage it," she said. "I know what I have to do in my matches."

Henin joined the French national team aged 15 and won gold at the 2012 World Junior Championships in Sharm El Sheikh. At 18 she left home in Nancy to train full-time in Paris. 

Her victory in Chiba was the first in the series for France since 2015, and offered evidence of how her career is peaking. Earlier in 2019, she took bronze at the World Championships in Manchester.

The Chiba win was of particular delight for Wiet Henin's mother. "My mom is really happy, she was crying," Wiet Hennin told World Taekwondo. "She is normally at the Grand Prix, she knows the level of the fights, and she knows that my opponents are all taller and bigger than me."

Like every athlete, she knows the time window will only be open for a limited time. "This is my passion," she said. "I know this will not be my job in the future."

She is currently pursuing a Master's degree in human resource management in Paris.

"I have dreamed about the Olympics since I was six," she said.

And it is not just her own dream: her mother never got the chance to box in the Olympics.

"It was my mother's dream," Wiet Henin said. "Now, it is my dream."

But the 25-year-old from Nannestad remains a potent threat in the under-80 kilograms category as the world's best taekwondo exponents re-calibrate their sights to the postponed Tokyo Games.

After announcing himself to the taekwondo world with a bronze medal at the 2014 European Junior Championships, Ordemann indicated that he was already capable of making his mark in the senior ranks as he earned bronze later that season in the French Open.

Since then he has amassed 20 medals in senior Open events, including eight golds.

In 2017 he won bronze at the Summer Universiade in Taipei, losing 12-10 to Raul Martinez Garcia of Spain. Earlier that year Ordemann had reached the quarter-finals at the World Championships in Muju, South Korea, losing 8-6 to Russia's eventual silver medallist Anton Kotkov.

The following year was a memorable one for the young Norwegian, as he began with a silver medal at the Turkish Open followed by golds at the Dutch and German Opens.

At the European Championships in Kazan he shared bronze, having lost 17-14 in his semi-final against Aaron Cook, the Briton who represents Moldova.

Then he produced one of the best results of his career to beat the odds-on favourite, Maksim Khramtcov of Russia, 27-14, and claim men's under-80kg gold at the Fujairah Grand Prix Final in the United Arab Emirates.

A superb round kick to the face from Ordemann in the third round drew gasps from the crowd and looked like it stunned the Russian. 

"Most of my head shots have a bit of power behind them," the Norwegian told World Taekwondo after the fight. "It puts them in a mental state that I quite like.

"It went according to plan – but my plans were quite simplistic; I don't go into detail. That limits myself."

He added: "I have been sneaking under the radar a bit. I have not had massive medals and I have not been really big on posting online, trying to get a big following."

At that point he was already looking ahead to the Tokyo 2020 Games, and putting emphasis on the importance of physical conditioning.

"Tokyo is very much on the horizon, and this medal puts me in a good spot for qualifying," he said.

"Injuries you can't really do much about: if it happens it happens.

"So I do a lot of 'prehab' - exercises to prevent injuries.

"This is the start of something good: I think you will be seeing a lot more of me on the podiums in the future.

"I am here to stay."

His season last year was relatively less successful – he took silver at the Turkish and Egyptian Opens, and gold at the Polish Open in Warsaw. 

But he was tantalisingly close to the podium in the season-ending events of the Extra European Championships in Bari, where he lost 5-3 to Kotkov in the quarter-final, and the Grand Prix Final in Moscow, where he also reached the last eight.

As Ordemann looks ahead to the re-staged Tokyo Games, he knows he has real medal chances… 

Alessio's surprise landmark achievement took place in Manchester on May 18 in 2019 as he took on Jordan's Rio 2016 champion Ahmad Abughaush in the men's under-74 kilograms lightweight final.

While the Italian towered over his opponent at 6ft 4in, the Jordanian brought to bear a wealth of experience, having earned the honour of being his country's first Olympic champion.

But the young Italian, who had only turned 19 the previous month, found the way to earn an 18-11 victory.

It was the second major gold for his collection following his win in the under-73kg class at the 2017 European Junior Championships in Larnaca.

"I am so happy and proud of my achievements," he told World Taekwondo. "This has been my dream since I was a child, so it was really great to arrive in the best condition I have ever been in and win gold.

"I had to train really hard for this competition because I knew Abughaush was going to be very strong. When I won, I couldn't believe it, and I think this is only the start."

Alessio accepts that his height can offer some advantages, but points out that it can also work the other way at times.

"I guess I have a small advantage because of my height, but if my opponent is quick and smart, I find this difficult. It is not always easy," he says. "But my favourite action is kicking, which I am good at because of my long legs!"

This was evident in the Manchester final, where Alessio scored well with his kicks to Abughaush's head, but was vulnerable to swift body punches from his opponent.

In the wake of his gold medal performance, Alessio said: "Tokyo 2020 is a dream, but I am not looking that far ahead. 

"I am living in the present and just trying to be the best I can be."

For the following World Taekwondo Grand Prix Series, Alessio moved up to the under-80kg welterweight class and the rest of 2019 became something of a learning curve as he competed at events in Rome, Chiba and Sofia without getting onto the podium – although he was only one round away in Japan.

But Alessio's season finished on a high note in November as he took bronze at the G4 Extra European Championships on his home ground of Bari, having suffered a narrow 15-13 defeat in his semi-final against Russia's eventual champion, Anton Kotkov.

"Tokyo 2020 is my objective of course," he said. "But I want to continue working hard and step by step I will manage to make the best results in all my future competitions."

Britain's women have established a golden tradition at the Championships in the space of the last 20 years, with double Olympic champion Jade Jones claiming her first title in Manchester to complete her medal set in the under-57 kilograms category.

Sarah Stevenson was the first British woman to win a world title when she claimed the under-72kg gold in 2001, and she added the under-67kg title ten years later.

Bianca Walkden has also won the last three heavyweight over-73kg titles.

Sinden joined the golden crew thanks to a 24-19 win in the under-68kg final over the favourite, Spain's Javier Pérez Polo.

British men have reached the podium at the World Championships over a period of more than 40 years, with Lindsay Lawrence winning two silvers and a bronze between 1979 and 1983.

Sinden, who comes from Doncaster, took under-63kg bronze at the 2017 World Championships in Muju, South Korea, before taking two steps up to the top of the podium in 2019.

"I went out there to see what I could do," he told World Taekwondo.

"Ultimately, I put the work in and that is what got me the gold medal.

"Being Britain's first male champion is also great and I am really lucky to be the first one from the team.

"The girls are so dominant in the sport, so the men need to step up our competition."

Sinden added that his "emotional" defeat in the previous year's World Taekwondo Grand Slam in Wuxi, China, where he was beaten in the final by home athlete Zhao Shuai, had caused him to review his training.

"I looked at what I needed to do better," he said.

"I implemented everything I needed to change in my next three events leading up to the World Championships and went to training camp."

Looking ahead to this summer's Tokyo 2020 Olympic Games, he said: "I want to come home with the first British men's Olympic gold medal.

"I have had a lot to improve on, but I have a lot of drive."

Since then that drive has continued to take him to the heights of his event, although he has missed out on gold on two recent occasions.

Pérez Polo avenged his World Championship final loss by beating Sinden 19-11 in the G4 European Championships under-68kg final in November 2019, and a month later at the the Grand Prix Final in Moscow the Briton took silver after defeat by South Korea's Lee Dae-hoon.

At the first of the three World Taekwondo Grand Prix series meetings this year, in Rome, Jelić - who had not managed to score a single point in the first two rounds of her women’s 67 kilograms final against South Korea’s Kim Jan-Di - turned a silver medal into gold in the last 10 seconds as she landed a spinning back kick followed by a front kick to win 8-3.

"The fight is not over until it is done and the referee says so," Jelić said. 

Two weeks earlier in the Manchester Arena, Jelić had lost by just one point to Brazil’s Milena Titoneli in the round of 16 at the World Taekwondo Championships.

Two weeks on, Jelić used that disappointment and frustration as motivation.

"You can lose everything in one second," added Jelić, who has moved from her family home to take up regular training in Split. "Never give up. Just keep trying. I feel amazing because two weeks ago I lost at the World Championships. So I can say I didn’t give up and now I look forward to future matches.

"I think what was missing at the World Championships was my self-belief. Here I trust myself and my coach and the people around me.

 "I was in taekwondo since I was a kid. From the start it wasn’t so serious but later I wanted to do more and more. I was watching Grand Prix meetings on my laptop and was hoping to get here. Now I’m here I’m very grateful and happy.

"But I want to put dreams in front of me so I can try to reach them. So maybe my next dream is to go to an Olympic Games and win a medal."

Meanwhile, Jelić is building an impressive collection of other medals. Last year she won gold at the Mediterranean Games and the Moscow leg of the Grand Prix. And she followed up her success in Rome by taking silver in the second Grand Prix series meeting in Chiba...

Larin landed awkwardly on his finger mid-way through the second round, meaning that he had to fight the remainder of the gold medal match with practically one hand. To make things worse, he was up against pre-tournament favorite, Kyo-Don In of Korea, proving just how impressive Larin’s eventual victory was.

Larin has always enjoyed entertaining in the ring, often pushing his body to its limits. Before his taekwondo career kicked off, Larin was a talented gymnast until a fracture to his hand when landing a stunt proved to be gymnastics loss and taekwondo’s gain.

Larin’s outgoing personality combined with this desire to entertain formed his captivating style of fighting, most notably his trademark spinning kicks to the head of his opponents.

However, experience has taught Larin that he must pick his moments to unleash these signature moves.

“It is always good to entertain. I like to perform my spinning kick moves, but you need to know when to use them. They can be useful against some opponents but not against others.”

The final match proved to be a fight where Larin had to remain composed and show his adaptability.

“In the final there was no need to use my spinning moves. I felt like I was always in control. Also the dislocation of my finger meant that I didn’t want to take any risks.”

A dislocated finger would be enough for any athlete to lose their concentration, but Larin admirably fought on to claim gold in the men’s +80kg weight category. He hopes that his performances in Rome will encourage the next generation to take up taekwondo.

“I aim to inspire people. I hope that I show youngsters that if you work hard, never give up and always believe in your spirit then you can achieve anything you want. No matter what,” he said.

“I hope that young people will watch my performances and see me claim this world title, and maybe they will think that they can one day win a big competition too!”

Larin’s impressive resolve and never say die attitude, even in the face of adversity, means that he is yet another great role model in the world of Taekwondo.

Furthermore, his adaptable fighting style means that he is a worthy match for any taekwondo star and, if he can stay fit, he will be a force to be reckoned with for years to come.

For Great Britain’s newly crowned junior world champion, Jordyn Smith, that is only half the challenge.

Two days at school in her hometown, Falkirk, Scotland and three days in Manchester, England where she trains with GB Taekwondo’s World Class Performance Programme make up Jordyn’s week.

However, she appears to be striking the perfect balance as she demonstrated this week at the World Taekwondo Junior Championships in Hammamet, Tunisia where she won gold in the -44kg weight category.

“I’m just doing it part time at the moment. Once my exams are finished in May I’ll be training five times a week,” she says. “All the staff at GB are really helpful and really supportive of the school. I always have meetings at the start of the week so I can slot in times when I can do my study as well as training.”

The training certainly seems to be paying off and it was clear just how much the gold medal at the World Championships meant to her. Having overcome Thailand’s Jongkolrattanawattana in the final she dropped to her knees with joy before running round the court with the Union flag flying behind her.

A day later and she had not really come to terms with what she had achieved. “It’s still not really sunk in yet,” she says. “It’s a bit of a shock. Everyone is asking me how I feel and I don’t know what to say.”

That is understandable. Jordyn has been practicing taekwondo since she was four so this title may still feel like a dream.

“I remember going into my first session and being scared of all the loud shouts and the kicks. I used to always run out and hide behind my Dad. But I remember a couple of weeks in, my Dad said this is the last time I’m taking you if you don’t like it. There must have been something in me that day because I said ‘no, I want to do it.’ I think as long as you enjoy the sport then definitely do it.”

That decision clearly paid off for Jordyn and she is now looking forward to moving up to senior level.

“I can fight seniors this year and I’m hoping to fight some senior events and collect some ranking points. Next year that’s when I officially turn senior.”

“I watch them and their commitment to the sport is just amazing. Sometimes I watch them and I just think ‘wow’.”

“Ever since I was little Tokyo was my dream. It might be a bit of a big statement right now but it’s still possible.”

It was a fitting end to Vanja Stanković’s school days: On June 26 in 2017, the 19-year-old Serbian won the gold medal in the female under 49 kilograms category in Muju. But it was not something she had anticipated before she flew out to South Korea. "I did not expect to get to finals I just wanted to show my best and believe in myself and see what will happen," she said in an interview the day following her victory.

That victory adds yet another honour to the increasingly crowded medal wall at her dojang, Belgrade’s famous Galeb - which means "Seagull" in English - Taekwondo Club. Under head coach Dragan Jovic, the club has produced two Olympic medals - London 2012 gold medallist Milica Mandic’s and Rio 2016 silver medallist Tijana Bogdanovic’s Rio silver - and now a World Championship title, Serbia’s first-ever. 

"Galeb is really the most successful club in Europe," Stanković, already a gold medallist at the European Under-21 Championships in Bulgaria and the Belgian Open before Muju, said. "We have good coaches good system of training, we train so hard every day, twice a day." 

Galeb is not just about training, Stanković claimed. It is also about camaraderie. "In our club we are like a big family, everybody loves and supports each other, and everybody wants to come to the club," she said.

If teamwork is one reason for Stanković’s success, another is her apprenticeship in the sport from an early. "I started when I was maybe eight-years-old, my friend started it and she liked it and asked me to go with her," she recalled. "It was a game and I liked it – and now, nine years later, I am here."

Another reason is self-belief. "We always believe in ourselves and in our club and in our country," Stanković said. "From the start, my coach Uroš Todorović was helping with my mental strength: He made me believe in myself.

"Before Milica’s gold in London, nobody knew taekwondo, they would say, ‘Is it fighting with sticks?' But after two Olympic medals – especially Milica’s in London – there was a boom for taekwondo in Serbia and now it is one of the most famous sports. Everyone knows Milica and Tijana and Dragan.”

Having finished school, Stanković now plans to study economics at university but will continue competing in taekwondo. "I want to see how high I can go," she said.

As a fighter, the Serb’s core assets are speed, power and aggression. "I am not very tall, you know, so I try to be the fastest I can be – I try to surprise my opponent with speed," Stanković said.

And speed generates power. "I am not going for the KO, but I practice strong and fact and explosive," she said. "I always try to do my best – best speed! Strongest! That is what you see in the fight!"

In technical terms, Stanković boasts clean and powerful technique; in fact, the high roundhouse kicks she unleashed in Muju could be taken from the pages of a taekwondo textbook.

With the new rules coming in, her preparations for the 2017 World Championships were strenuous, with heavy priority on conditioning. "It is physically harder now, you need to push each other," Stanković, who focussed on a long process of weight training and leg strengthening, said. "I think for me, the new rules are better; the new style is more aggressive - more fight! - and more interesting for the watchers."

Though Stanković insists that she still enjoys both the training and the fighting of the sport, her final in Muju presented a stern test: She found herself taking on the defending world champion and Rio 2016 bronze medalist, Thailand's Panipak Wongpattanakit. Besides her experience, Wongpattanakit also boasted a height and leg-length advantage.

"The plan was to attack and don’t give her the chance to make contact," Stanković said of her game plan. "The plan was to break her fight, break her position, to move her and when she raised her leg, I would kick.

"Before a fight I sit quietly and I visualise the match: I see myself fast and strong and kicking the opponent in the head and body and the match is mine. I try to imagine…"

In the final, first blood went to Stanković in convincing style. She landed a picture-perfect round kick to Wongpattanakit’s head for three points – before being forced off the mats by the Thai’s counter-charge for a one-point penalty. The first round ended 3-1 to Stanković. 

In round two, Wongpattanakit  stabbed forward with her long front leg, but not connecting. She dominated the centre of the mats and forced Stanković out of the area for another penalty point, 2-3, which is how the round ended.

In the third round, the reigning champion had to score, but as she attacked forward, she went down, taking the board to 4-2 in Stanković’s favour. Then, as the Serb lunged in for a punch attack, Wongpattanakit landed her hook kick to the head but fell, meaning her points were deducted for holding. The Thai coach appealed against the decision but was overruled, leaving Stanković 5-2 ahead.

The board now read 5-2 to the Serb. The Thai won back two points with a body kick, but Stanković landed another wicked roundhouse to the head that dropped Wongpattanakit. "I did not think about kicking," Stanković said. "I just did what comes."

The score was 9-4, then 9-5. With 30 seconds remaining, Wongpattanakit tried  to score to the head only for her effort to backfire when she tumbled. The score was 10-5 – and that was it. Stanković was Serbia's first-ever world champion.

"I could not speak, I could not move, I just started yelling," said. "I could not see anything or hear anything, I just thought, 'I did it! I did it!’' Many, many times earlier I had tried to imagine that moment - how it would feel. It was the most amazing feeling, ever. “

A day later, when the dust had settled, Stanković was able to look back upon about her taekwondo journey so far. The key learning, she claimed, is self-belief.

Taekwondo markets itself as being about self-defence, self-confidence and self-belief but Stanković was never 100 per cent certain about the latter. She is now. "I always told myself that hard work pays off," she said. "I was not sure – but now, I am down with that: It does."

The Iranian-born Asemani fled her native land for Belgium in 2012. The refugee arrived in Belgium on Christmas Day, 2012. It did not take long for the former Iranian international - Asemani had won a silver medal at the Asian Games in 2010, but did not make it to the London Olympics in 2012 – to find her way to the Belgium national taekwondo team, under coach Karim Dighou and performance director Laurence Rase, on December 28, 2012. With financial help from local federations, the refugee was able to re-start competing around Europe.

But like every athlete, her highest dream was the Olympics and Asemani, an asylum seeker, was stateless. A ray of hope shone when International Olympic Committee President Thomas Bach announced the formation of a refugee team for Rio. That gave Asemani - then working as a postwoman in Belgium, while training part time - a last-chance opportunity to fight in Rio. "I was really happy as taekwondo is my life, and this was the one chance," she said. "After 17 years in taekwondo, it had been really difficult."

On April 13, she was granted Belgian citizenship - but it was not clear if she would be able to represent Belgium in Rio. At the European Qualification Tournament, Asemani - still fighting under the WTF flag - found herself facing off against Belgian athlete, de facto teammate and close friend Indra Craen. "It was a really emotional game," Asemani said. She emerged victorious in that match, and ended the European Qualification Tournament with a first place win in her weight class after defeating Finland's Suvi Mikkonen. The question now was whether she would fight for Belgium, or for the IOC's Refugee Team.

Her paperwork passed muster, and she was cleared to fight in Rio under the Belgian flag. "I got big help from the IOC and the WTF," she said. Asemani was ecstatic. "What can be more beautiful than to have a country at the Olympic Games?" she told AFP in an interview.

Her new passport meant an additional level of emotional support from her new nation. "I had lived four years in Belgium and been training with the Belgian team," she said. "The people of the country supported me and did everything for me and I got support from Karim and everyone. It was really good."

She fully bonded with the team. "It was really good, I had really good friends, we have grown together," she said. "It is not only sport, it is friendship and everything." Her special training partner in the lead up to the Olympics was none other than Craen.

There were significant differences in the training she went through in Iran and in Belgium. "In Iran, in the national team, we trained with girls," she said. "So, when I started in Belgium, it was really difficult to train with Karim and the boys." The famously tough training for Iran made her "strong", Asemani said, but in Belgium she found more leg control and more science in the programme.

Rio would prove to be a trial by fire. Asemani won her first two matches, then found herself facing 2012 London champion and eventual 2016 Rio gold medalist, Jade Jones of Team GB. The fiery Jones won the match, 7-2. Still, Asemani was through to repechage, where she narrowly missed out on a bronze medal against Egypt’s elastic-legged Hedaya Wahba, in golden point.

Asemani has mixed feelings about her Olympic result. "First, I had hoped to be in Rio; second, I wanted to do my best, and I think I did it," she said. But she admits that when she came home "it was too difficult for me, mentally". For four months, she stopped taekwondo.

"After Rio I could not accept that I had lost in golden point," she said. "Then I started my job in the post office - and I have really good friends in the post office - and they supported me and they said 'you must go one more time; you can do it; you are the best!' and that was really positive energy for me."

She returned to training and is now back on Team Belgium - this time, as a full-time athlete, training both mornings and afternoons. Currently, her sights are set on the World Championships in Muju, in June. "I want to be in the Worlds and I want to win and do my best as I did not fight in 2013 or 2015," she said. "It will be my first time on the Belgian Team."

How about Tokyo 2020? "I cannot speak about Tokyo, I think I will be too old, I want to see how my body is," said the 27-year-old. "I want to do taekwondo in my best condition and get the best result."

As for the future, post-Muju, she is mulling a return to study and a possible career in the Belgian police force.

As for the past, she has a lot of gratitude. "I want to say 'thank you' to everyone who helped me, I am really happy that I have met so many good people, and have good people around me," she said. "Especially Karim and Laurence and my boss at work - they were all really good for me."

How about a message for those refugees, displaced persons and asylum seekers worldwide who may consider following in her footsteps? "There are many people with hard life stories, but I think anybody can make their dreams," she said. "I want to say: 'try, always! Impossible is possible."

In the women under-57 kilograms category, the number-one seed and London 2012 gold medalist Jade "The Headhunter" Jones of Team GB faced off against number-two seed and arch rival Eva Calvo Gomez of Spain. Since London, the two have been engaged in a seesaw, back-and-forth rivalry. Now, Briton faced Spaniard under the Olympic spotlight for gold. Game on.

Combat commenced with the two battling for the centre of the mat, Jones looking more aggressive and stabbing at the taller Spaniard with her side kick. Then Jones' radar-guided front foot flashed up. The Headhunter drew first blood with a high kick. Seconds later, she did it again, doubling her lead. Disaster loomed for Calvo Gomez. The Spanish coach demanded a video replay but Jones' points stood, 6-0.

In the second, Calvo Gomez charged out, fighting at a furious pace and grabbing two points with body kicks. The British girl returned fire, taking her lead to 7-2, but the Spaniard rocked Jones with her own head kick. The board was now 7-6, with Jones - just - ahead. Given the one point differential, there was everything to play for in the third.

Both athletes came out fighting, but Jones' head kick was doing its wicked work, extending the Briton’s lead to 15-7. Despite a moment of drama- Jones' coach, Paul Green, appealed a head kick; it was denied - Jones kept her cool and extended her lead.

It ended 16-7 - a convincing win, a brilliant performance and a second Olympic gold for the "Welsh Wonder".

Jones - beyond exultant - ran off the mats and dragged Green up onto the field of play. She then ran a lap of honour around the Arena, streaming the British and Welsh flags, to the delight of the roaring crowd - which included 10 of her family members who had flown in from Flint, Wales.

"I know I am the best, but in taekwondo, anything can happen," Jones said, post-match, referring to the upsets in the previous day’s competition, when stars had fallen left, right and centre. Looking back on Rio, she is understandably proud. 

"After London, I did not want to be a one-hit wonder," she said, referring to 2012, when, as an unheralded 19-year-old, she had come from nowhere. 

"The run up to Rio was a different ball game, I had been undefeated all year, so there was so much pressure, so much expectation." Victory, she mused, had been almost a relief. "It was still joy," she said. "But more like, 'thank God'. Anything else would have been a fail."

Great Britain - the originator of football, rugby, cricket and boxing - has a powerful sporting tradition. Jones' latest gold - together with the silver won by teammate Lutalo Muhammad and the bronze won by teammate (and roommate) Bianca Walken - has planted taekwondo firmly on the British sporting map. "It is going from strength to strength, the team is getting stronger and stronger, we are becoming a force," she said. "Taekwondo is one of the main sports we are excelling in; I am proud to come from taekwondo in Britain."

With the country having won hosting rights for the 2019 World Championships, two Grand Prix events and the next Para Taekwondo Championships, Jones will be fighting in front of her home crowd once more. 

"I will try to be an ambassador and for me it is an amazing opportunity for friends and family to come and watch as usually, taekwondo is in faraway countries, so my family does not have the chance to come," she said. "Also, when it is in the UK, people say it is the best atmosphere."

However, 2017 marks a new ruleset coming into taekwondo - and one of those rules is that coaches will no longer be able to appeal head kicks, something Jones and Green have been tremendously successful at. She is unfazed. "I reckon a true champion can change and adapt," she said. "I still have back kicks and body shots and the rules will not stop me from going to the head."

As for inspiration, she cites Green and her grandfather. "My granddad took me to taekwondo at age eight, and he literally travelled the world and used his savings to get to the competitions," she said. "I still ask his advice."

She describes herself as "family oriented" and says she likes to "laugh, joke and be a bit silly".

But that is not her taekwondo personality. On the field of play, Jones is aggressive, dangerous, venomous. "I am a bit rough-and-tumble the way I have been brought up, I am not scared to go toe-to-toe," she said. "A lot of girls shy away from that; it is not natural to fight."

And she is a hard-core trainer. An acquaintance noted - with awe - that Jones and Green sometimes finish grueling all-day national team training sessions, then head out to private dojangs in Manchester for extra evening training. "I have quite an obsessive personality," Jones confessed, admitting to being "a bit bonkers". "Anything I do, I don’t do half-heartedly."

This explains her ambition. "The goal is to get three Olympic golds," she said. "The biggest legends, - Team China’s Jingyu Wu and Team USA’s Steve Lopez - have not been able to do it, so that shows how much of an ask it is". 

She claims to fear nobody on the circuit, but knows that up-and-coming fighters will be gunning for her over the next four years. Still, her age is to her advantage. "Being only 23, I don’t think, 'what else can I do?,'" she said. "I feel like I can get better."

So, London and Rio - and a historic third gold in Tokyo? "Could I be the chosen one?" she wondered aloud. Then her self-belief kicked in. "I believe I can do it," she finished. 

That result was thanks to the efforts of three woman warriors: gold medal winners Jade "The Headhunter" Jones, Bianca "Queen Bee" Walkden and Charlie Maddock.

Charlie Maddock? Yes, Charlie Maddock. Her name is not as well-known as double Olympic gold medalist Jones or world champion and Olympic bronze medalist Walkden, but her lack of recognition and experience did not stop the up-and-comer from beating the 2016 Rio Olympic champion in the female under-49 kilogram category, Korea’s So-hui Kim.

The Kim-Maddock battle on day one of the Grand Prix proved to be a clash not just of fighters, but also of fighting styles. Kim is a master counter-kicker, with a wily tactical game and excellent footwork. Maddock, on the other hand, is an aggressive fighter, with a never-step-back, take-no-prisoners style.

As the buzzer sounded for the first round, Maddock - totally unintimidated by Kim’s pedigree - surged out, fighting strongly and immediately pressuring her opponent. The Korean fought back gamely; she appeared to have decided that she would not let Maddock play her customary steamroller game. It was a lively round - but ended without a score. The second round kicked off with Maddock continuing to apply forward pressure. Kim reverted to her normal, evasive style, leaving Maddock to expend energy firing multiple kicks. But it was Kim, fighting more economically, who looked the more dangerous player: she failed to score by a whisker with two head shots. Round two ended scoreless.

Round three continued in the same vein with plenty of kicking, but no contact and no points. Surely, at this stage, Kim’s superior experience and ring craft would pay off?

Not necessarily. With just 12 seconds on the clock and the board empty, Maddock riposted a Kim attack with a reverse spinning turning kick to the head - then-swung her leg back into a round kick to the head, without putting her foot down. It was an extraordinary display of leg control, brilliant timing and spectacular technique. The scoreboard lit up, and the British girl was ahead 4-0.

In the final seconds Kim, a cagey, tactical fighter, was powerless to respond: her arsenal did not include the high-scoring techniques necessary to turn things round. The match ended with a well-deserved 4-0 win for the British girl who is clearly charmed in Azerbaijan - her previous big win had been a gold medal at the European Games in Baku in 2015.

Speaking the day after her win at the Grand Prix Final, the 21-year-old from the English town of Stoke-on-Trent proved pretty and petite, but fizzing with life. Her nickname is "pocket rocket" - a reference to small size and high energy.

Combative energy is in Maddock’s DNA. She got her start in combat sports at the tender age of five at home. Her parents had met through martial arts, and her father was a kickboxing instructor. "I kind of fell in love with it," she said. Years later, sensing his daughter’s potential, her father put her name forward for "Fighting Chance" - GB Taekwondo’s talent scouting program.

"Fighting Chance" plucks combat sports athletes from fields including taekwondo and kickboxing to see if they have what it takes to join the grueling, elite training program at Great Britain’s medal factory - the National Taekwondo Centre in Manchester.

That application was three years ago: Maddock was invited to join the elite and has not looked back since. Naturally, her parents were delighted to hear the news of her victory in Baku. "Dad and Mum were buzzing, they were over the moon," Maddock said. "Mum was screaming down the phone – it was a nice Christmas present."

Maddock’s favorite techniques are her "check kick" - a stabbing side kick - and her punch. "Coming from kickboxing, I like to punch," she said.  She also favours head shots, but the game-winning blow she deployed against Kim in Baku is a relatively new weapon in her arsenal. "The reverse turning kick is a funny one," she said. "I have been working on it for ages, so it was nice to get it in the last seconds."

As a player, she considers aggression as one of her strongest qualities. "I like to press the match down and wear the opponent down to the point where she thinks she has no other option." she said. "I am really strong and I am quite fast as well. Put the two together and they work really well."

However, she recognises that now, in premium-level competition, aggression is not enough. She has to add a layer of sophistication to her game. "I am working on being manipulative, on controlling distance and being calm and composed," she said. "Being aggressive is good - but not all the time."

Perhaps surprisingly, there is no boyfriend in her life - training does not leave much time for romantic distractions - and she lists her non-taekwondo hobbies only as "shopping". Regarding future plans, her main aim is Tokyo 2020. In the shorter term, she hopes to qualify for the World Taekwondo Championships in Muju 2017. On the way to Muju, she will be taking part in some smaller tournaments in the run up to the summer.

She thanks her sponsor, Phil Wettem Say Scaffolding - "without his sponsorship, some things would not have been achievable" - and the staff at Manchester, as well as her parents for bringing her up in combat sports. She also pays tribute to the golden girls of British taekwondo.

"To be honest, I never knew what the sport entailed at first, but when I came to the first phase of "Fighting Chance" then I saw that these girls are pretty good," she said. "I wanted to achieve what Jade and Bianca have achieved."

Having joined GB Taekwondo’s two national heroines on the podium in Baku, she may be on her way to doing exactly that.

"Everybody is extremely happy, they cannot wait for me to come," she said following Rio 2016. "But I will have only about 10 days’ summer break - then I start school on September 1."

Yes, you read that right. The Serbian who captured Olympic silver in a tight, hard-fought bout against Team Korea’s So-hui Kim in Rio de Janeiro is not a pro athlete, working out full-time, day in and day out: she is still a high-school student.

Which explains why she wants to extend her thanks not just to her coaching team, but also to her school buddies. "I had great support from my friends and my teachers, they helped me a lot during my period of absence," she said.

Unsurprisingly, perhaps, the upbeat 18-year-old wunderkind started taekwondo at a very tender age.

"When I was four, my parents took me to a taekwondo club and I fell in love with it at first sight – it is very attractive," Bogdanovic said. "In taekwondo, you have a lot of adrenaline as [the match] only takes six minutes - you have to withstand the pressure in a short period, you have to show yourself."

She did exactly that in Carioca Arena 3 on the first day of the four-day taekwondo competition. Fighting her way through the preliminaries, the number-eight seed shocked the punditry by ejecting the athlete who was widely considered the most dominant fighter in the sport: China’s previously unbeatable Jingyu Wu, a double Olympic medalist and the top seed in the women under-49kg category.

By the evening, Bogdanovic - whose previous biggest wins had been gold at the European Championships and bronze at the World Championships - had battled her way through to the finals. There, she would face off against Team Korea’s So-hui Kim, the seventh seed.

From the outset, the Serbian teenager, with her height advantage, fought forward, forcing the Korean to dance around the edge of the mats. But it was the more experienced Kim who was more accurate with her legs, winning the first round 2-1. The second continued the same way, with Kim displaying lively footwork to escape the Serbian’s attack. Bogdanovic, trying to land a punch, took a crescent kick to the head; the round ended 5-2.

In the third, the score was 4-6 to the Korean but Bogdanovic applied maximum pressure, and Kim visited the mats repeatedly. In the last 11 seconds, Bogdanovic was virtually chasing her target around the field of play. Kim held off this last-minute charge, taking the match and the gold medal, 7-6 – despite going down in what looked like the final second.

Some observers thought that Kim, who had racked up almost the maximum number of penalties for falling, should have been disqualified for her last-second fall - but not her opponent.

"I feel a bit sorry that everybody is talking about that last second, as I think that all people are allowed to make mistakes - even if you are a judge," said Bogdanovic. "It is not something that we should bother about too much."

Just being at the Olympic Games was an awesome experience for a schoolgirl - though at first she was underwhelmed.

"Since this is my first Olympic Games, I was not really impressed by the Olympic Village and everything, but as time went by, I was really overwhelmed by the atmosphere in the Serbian team, exchanging good, positive vibes between the athletes on the team," she said. "I enjoyed all that experience"

Of course, the highlight was winning the medal.

"It was a great experience in terms of my development because it is not only the day of competition, but all I had gone through before the competition, all the preparation," she said. "The day of competition is like the top of the cake - when you go to an exam you show what you were working for, so of course, I am happy and proud."

She rates her strengths as a fighter as flexibility and technical skill: her favored technique is that classic of taekwondo, the round kick to the head. In terms of her athletic personality, she is still a little unsure. "In this period of my life, since I am still 18, I am still developing and would describe myself only as ‘well disciplined,’” she said. "I just listen to my coach and try to be the best student."

Like many teens, her future plans are unclear. She has no boyfriend, but is "very interested and motivated to work with kids." She plans to go to university, but has not yet chosen a major.

Naturally, the sport she has been practicing for 14 years will remain central in her life.

"The best place to find me is our taekwondo club as I really feel great when I am in training - I feel myself there, I feel I belong there," she said. "Also, when I have time, I am always with friends from the club."

Fast forward over two decades and two continents and so it has proven - and then some.

Her son, Jaouad Achab, made it to world number one in the ultra-competitive men’s under 68kg category and narrowly missed a bronze medal for his adopted country of Belgium at Rio in 2016.

The junior Achab’s taekwondo journey started at the tender - very tender - age of three. As per her earlier vow, his mother had put his older brother and sister into taekwondo classes. When they came home, their tiny brother would insist on kicking and sparring with them.

Seeing his unusual attachment to the sport, his mother took him along to the club. The coach said he was too little to begin, but his mother pleaded with him to let this child with the “unnatural talent” give it a go. The coach finally relented, but said it would be for just one session. That session dragged into two, then three.

“People saw something special in me,” he said, looking back.

By the age of six, Achab was fighting in and winning competitions - first for his club, then for his city and then on the Moroccan national circuit. At the age of 13, he won the national cadet championship. However, for what he calls “political reasons” of the local Federation, he did not make it onto the national squad.

In 2009, Achab’s family decided to emigrate to Belgium for a better future for them all - and for more taekwondo opportunities for their wunderkind son. He started fighting immediately upon arrival on both the Belgian and European circuits. “I had some wins, some losses, as I had not had any international experience,“ he recalls. “But little by little, I understood international-level competition.”

He fought in the 2013 World Championships, winning two matches. In 2014, he became European champion. “That was my first dream to achieve,” he said. “After that another door opened: After the Europeans, I became a professional athlete with BLOSO, the Flemish Governmental sport organisation, which supported me a lot. From then on, I have got a lot of results.”

At the 2015 World Championships in Chelyabinsk, Russia, he found himself facing off against Mexico’s Joel Gonzalez, a two-time world champ, in the final. “I had to have full concentration, if I lost it for one second he could go very fast to my head,” Achab recalls. “I controlled the fight for first round, and the second round, I worked harder and it was 2-0 to me, then in the third he went to the head but at that moment I seized the advantage and scored to his head! It was 5-2 and I had to control the fight to the end - every second was important. I controlled it to the finish.”

The result was a World Championship title. “It was the most important competition of my life and the biggest day of my life,” he said, classing that - along with the European Championships and the World Universiade, which he also won in 2015 - as his top competitive achievements.

To overcome this, he suggests removing the sensor from the sole of the foot-sock, and toning down the power required to score points on the Protector Scoring System. “Then, you would see beautiful kicks - people would kick with more spinning and double kicks,” he said.

Outside the dojang, he likes to swim, play snooker and shop for clothes. He also reads a lot; the book he is currently working through is on achieving one’s goals and appreciating whatever one has. Looking beyond his competitive career, he expects to be a physiotherapist and coach taekwondo.

Although firmly in the Belgian camp following his award of citizenship, he is gratified when he hears that many sports fans in Morocco are wondering why he did not make ttheir national squad years previously, and are now urging his return.

Having made a personal and family odyssey from Morocco to Belgium in order to achieve success in taekwondo; having learned three new languages - French, Dutch and English - in the process. Achab now looks set to scale the pinnacle of the sport. His mother’s ambition was one contributing factor in his success. His “unnatural” precocious talent was another. To what other factors does this young man attribute his success so far?

“I am someone who always thinks positively,” he said. “Physically, people say I am small for the under 68kg category, but mentally, my mum says I have the heart and mind of a heavyweight.”

The 24-year-old Swede was competing in the female under 67kg category at the 2014 Queretaro World Taekwondo Grand Prix Final - a key gateway to qualification for Rio 2016. Even for an athlete with 13 years of experience in taekwondo, the day ahead, a walk through fire against three world-class opponents, as a daunting prospect.

“I was so nervous in the morning - I am never that nervous! - that I had to lie down before the first fight,” she said.

That fight was against long-time rival Nur Tatar of Turkey. “We are good friends and have been for a long time so it is hard to fight her in that way,” Johannson mused. “And she is a very, very strong fighter.”

From the starter bell, things did not go according to plan. The Swede fell behind in the scoring. But her mind was still in the game. “In the first and second rounds I was under, so [in the third] I had to pressure her and keep my focus,” she said. “I did a random turning kick to the body then snapped it to the face and got her in the last round with video replay. 

"Since the electronic hogu, it has been much more frontleg kicks and if you want to win, you need to do that, but I also like to double, to spin, to go high - I am a headhunter’"

That secured Johansson her first victory of the day and engaged all her gears. “After that, I felt so much better,” she said. “I usually need one fight to get in the mood.”

Her next opponent was Taiwan's Chia Chia Chuang, who Johansson had beaten 9-2 in the Manchester Grand Prix. “I knew I could beat her but I knew she wanted to beat me,” she said. “I went into the fight with the attitude that this is all in!”

Johansson’s second match would prove to be even more of a nail-biter than her first.

The Swede took and held a lead in the first two rounds then, in the dying seconds of the third, Chuang caught her in the head, evening the score. Johansson, momentarily discomfited, held her fire as the match resumed. “I was just thinking it was better to go to the golden point because my focus was somewhere else,” she said.

The drama implicit in the golden point system is something that taekwondo fans may relish, but is a devilishly nervy business for fighters. One mistake and it is all over. It speaks volumes for Johansson’s mental preparation that she consciously decided to settle matters via sudden death.

In golden point mode, the bout lasted a minute, then Johansson saw an opening and “took the shot,” slamming Chua in the body, earning a point and a place in the finals. “A very, very tight fight,” was Johanasson’s judgment. The battle for gold would be against another long-time rival, France’s Haby Niare - the world-ranked number one.

“I was nervous but in a good way, I was thrilled to be in top eight and then to be in the Grand Prix final,” Johansson said.

Niare is one of the trickiest female fighters in the sport. She has an arsenal of unusual kicks and a bag full of surprises . “But this time, she did not surprise me,” Johansson said. “Maybe the main reason is I was not as tired as her, and I could control the fight.”

Johansson looked stronger than the French girl from the get-go and proved tactically superior, controlling both distance and tempo. Ironically, this fight - Johansson’s last of the day - proved the easiest. She took the lead from the start, and took the match 4-2. “I was in the lead and kept her away,” she said.

After stepping down from the gold medal podium, she was visibly elated.

“I had three very tough fights against three very tough opponents, so I could not be happier - this is one of the happiest days of my life,” she said in the post-medal ceremony interview. “I was very tired at the end, but I kept control of the fight, I did my style.” Her style might be dubbed “orthodox taekwondo”, but with a wide technical range.

“I have a lot of weapons,” she said. “Since the electronic hogu, it has been much more front-leg kicks and if you want to win, you need to do that, but I also like to double, to spin, to go high - I am a headhunter.”

In the analysis of Team Sweden Coach Niklas Anderson, Johansson had put almost all the the parts in place: technical, tactical and physical.

“She is one of the most technical fighters; she does the ‘new style’ with the front-leg cut kicks, but she can also do all these turning kicks,” he said. “Tactically, she is very smart, with a good understanding of the sport, and physically she is very explosive, very strong. The only problem was the mental part.”

Johansson agrees. “When I am happy, I am happy; when I am not happy, I am very angry!” she said. “It is both a blessing and a curse to feel things so deeply.”

Recently, she has learned to settle her soaring- plunging emotions. ”I have a secret - I have a mental coach!” she said. “He makes me see it from a whole other perspective, it has been a lot of self-belief; confidence has been my problem.“

Anderson reckons the mental coaching has slotted the final piece into Johansson’s puzzle.

“She had been very up and down, but now she is much more balanced; even if she is behind on points she does not panic,” he said. “This has been the last step for her to take. She has been in five Grand Prix and in four finals, and that shows player stability.”

Even so, Johansson’s newly acquired head game could not stop the rising elation she felt after conquering the nerves prior to her first match. “I fight with joy because I love it, I don’t earn much money,” she said. “I feel joyful and aggressive and on fire.”

A full-time taekwondo athlete – she subsists on a Swedish Olympic scholarship and a salary from her club - based in the northern Swedish town of Skelleftea, located “up in the woods”.

Johansson is, like most of her rivals, firmly focused on Rio 2016 qualification. “I think that is when I will be on top of my career, I will be 26 at the time,” she said. “If I get there, I just want to do the best fights of my life.”

And post-2016?

“After the Olympics, we will see. maybe I will go for four more years, or have a family and have babies - I love babies!” she said. “If I can continue working in taekwondo, that would be a dream too; I love coaching my friends and my team.”  

France’s Niare, ranked number one in the slot in the world, is one of the least conventional fighters on the circuit, surprising the crowd and her opponents with kicks unleashed from impossible angles. Sweden’s Johansson, on the other hand, is a textbook taekwondo technician, firing from a textbook arsenal

On the night, it proved to be a victory for convention over flamboyance: In a masterly tactical display, Johansson controlled pace and the distance, taking the match, and the gold, 4-2. Still, Niare - nicknamed “The Abigator”, a play on her name and the carnivorous reptile, by her friends - accepted defeat gracefully, accepting her silver medal with a grin that rarely leaves her face. 

“I know I can win, I know I am better, but I was tired,” Niare, 21, said, conceding,”[Johansson} is a good fighter, and yes, she controlled the fight."

Tall, leggy and lithe as a leopard, Niare has worked for French railroad company, SNCF. In person, she proves as charming and bubbly a personality as she is formidable a fighter.

A native of Mates la Jolie - a suburb of Paris where she is widely recognised for her taekwondo achievements - Niare boasts a 2013 World Championships and a 2010 European Championships as well as her Grand Prix Number One ranking. She holds a 1st dan black belt in taekwondo, an art she has been practicing for a decade.

At the Rio 2016 Olympic Games this summer, she won a silver medal.

“Physically she has very special technique, with spin kicks and face kicks,” said French coach, Medhi Bensafi. “She is special and spectacular, not a conventional style.”

Indeed, Niare’s most eye-catching technique is the kind of move seen in kung fu movie fantasies rather than in real-life sporting competition: A heel hook kick that she unleashes - almost impossibly - from up close.

“I love the ‘scorpion kick’, in my team that is the name for this kick,” she said. “When we are in the clinch, when she thinks I can’t do anything - then I fire that! But I need to do it fast and if you want to do this kick, you need to be very flexible.”

She is certainly that, but insists that she is not naturally supple, claiming “I am always stretching, I work hard!” Her hobby, outside taekwondo is hip hop dancing which, she says, helps with fighting rhythm.

In the run-up to the Querataro competition, she trained heavily in endurance, in preparation for the city’s altitude. Technical preparation focused heavily on sparring with the team, as well as video analysis of the competition.

“Mental is most important for the fights, it’s all in the spirit,” she said. “The winner is not always the best, the winner is the one with the head game: I think it through round by round, I know what my work is and I don’t panic.”

That self-analysis is backed up by her coach. “Haby is a player with big determination,” said Bensafi. “She has only one thing in her head: to be the best.”

Niare is full of praise for the WTF Grand Prix Series. “It is very good for us athletes, as now we can fight more and we are more active,” she said “And we want to do the best."

The Yorkshire athlete battled on-the-mat adversity to become Great Britain's first-ever Olympic taekwondo medallist in 2008, and personal tragedy to claim her second world crown three years later.

In a discipline stacked with emerging young stars, it is testament to Stevenson's extraordinary will to win that she remained at the peak of her sport for almost 15 years.

Her proudest achievement came in 2011 when, with both her parents back home suffering from terminal illnesses, she won the world title in Gyeongju, South Korea.

"I was so close to not coming because I didn't want to leave my parents alone," said Stevenson after her victory. "But my family came together to help and I went out there to win it for them."

Stevenson had been tipped for stardom when she was still a teenager, winning the world junior title at the age of 15 and entering the senior ranks at a time when taekwondo was just being accepted into the Olympic programme.

She made her Olympic debut at Sydney in 2000, at the age of only 17, where she lost a bronze-medal match, and the following year she went to Jeju in South Korea, where she beat Chinese world number one Chen Zhong to add a senior world crown to her collection.

Although Stevenson was disappointed by a first-round defeat in her second Olympics at Athens in 2004, when the Beijing 2008 came around she was strongly favoured for gold, with only home hopeful and old foe Zhong seemingly standing in her way

The pair met in the quarter-finals, with Zhong apparently progressing with a tight 1-0 win, although video replays clearly showed Stevenson connecting with a two-point head-kick five seconds from the end.

After a furious team protest, the judges reversed the result in Stevenson's favour, but the Briton, ill prepared and roundly booed by the home crowd, was beaten in her next bout by Mexico's Maria Espinoza and had to settle for bronze.

It is a mark of Stevenson's incredible drive and ambition that while those around her celebrated her piece of sporting history, she headed home from Beijing in the firm belief that the gold medal had been hers for the taking.

Restarting her training programme back home in Manchester with renewed vigour, it seemed that nothing could get in the way of her path towards Gyeongju and onwards to home Olympic glory at London 2012, until she was given the devastating news about her parents.

In the months that followed her world title win, both Stevenson's parents passed away. In training, she was struck down by a cruciate ligament injury. Yet still she battled on. She had the honour of being selected to read the Olympic Oath on behalf of the athletes at the Opening Ceremony. 

But, her injury-truncated build up to the Games led to an early elimination.

In 2013, Stevenson announced her retirement from competition, and her intention to take up a coaching role in the Great Britain team. Shortly afterwards, World Taekwondo President Chungwon Choue announced that she been appointed to the world governing body's Executive Council.

On day four of the WTF World Taekwondo Junior Championships in Burnaby, Canada, Winnipeg native Skylar Park delivered exactly that.

The final of the female under-59kg category pitted Park against the smaller Yen Hsin Yeh of Chinese Taipei. Almost at the opening bell, the hometown girl went one up with a body kick, prompting a fierce firefight as Yeh fought back. 

But it was Park who extended her lead to 2-0, then 3-0 - the last with a thwacking round kick to the body that drew gasps and cheers. Some messy clinchwork followed before regular action resumed. Both girls then exchanged a series of head shots. The round ended 3-0 to Park.

In the second, Park again wasted no time, scoring with a fast head kick - then another – before tumbling to the mats after Yeh connected with a head kick of her own. The board surged to 12-3, but the lass from Chinese Taipei was still in the fight. 

She counterattacked with determination - but it was the Canadian fighter who landed yet another head kick. By now, she was looking very, very dominant. A break in the torrid action was called, with the bout at 15-4, as Park’s torso armour was re-secured. 

Park landed a picture-perfect side kick that did not register on the PSS, then was forced out of the ring. Both girls clinched and fired head kicks, the two fighters’ techniques almost cancelling each other out. But Park’s technical mastery and excellence of technique were becoming evident - she scored with a side kick from the extreme close range. The round ended 16-5.

As the bell rang on round three, Yeh had everything to fight for. Both girls were now fighting using the entire ring to manoeuver - with Park again unleashing a textbook side kick. Then Yeh landed an out-of-nowhere head kick, raising her score to 8-16. There was a brief slowdown - the prior tempo had been too fast - then Park’s cut kick scored again for 17-8. 

Yeh was looking desperate. She hopped across the floor, flicking our leading leg on the high line, hunting Park’s head; the Canadian did well to evade. Then - suddenly - it was all over: the Canadian impacted with a head kick that gave her the victory on a 20-8 point difference. It had been a fine performance of clean and stylish taekwondo that delighted both the crowd and her team mates.

Park bowed to the crowd, dashed to the stands, grabbed a national flag and stormed back onto the stage - where a duo of beaming Mounties, in full dress uniform, joined her for an impromptu (and unscheduled) victory celebration. And if the ringside hug between Park and her coach looked particularly tight, it was - they are also daughter and father.

Park’s seizure of a World Championship title was, perhaps, predestined: she has not two, but three generations of taekwondo blood running through her veins. The daughter of Master Jae Park (her coach) she is the granddaughter of Master Deuk-hwa Park, who migrated from Korea to Canada in 1977; out of his 10 grandchildren, nine hold black belts. The family runs a successful dojang in Winnipeg.

With this pedigree, it is not surprising that Park, 17, has been doing taekwondo "since I could walk." Her father recognised that she had the strong mind that the sport demands as early as age three. Today, she wears a third-dan black belt.

The gold-medal match went according to plan. "It was just to go there and fight with confidence, to fight how I know I can," she said. "The plan was to go in strong from the beginning."

She plans to transition up to seniors, and has already gone toe-to-toe with world-class senior competition at the Dutch and Belgian Opens in 2015. In the Dutch competition, she faced off against 2016 Olympic silver medalist Eva Calvo-Gomez, losing just 6-3. For a junior to lose by such a small margin to one of the top players in the game suggests stratospheric potential.

With junior ranking points now being transferable to the seniors, she expects to be competing in the elite Grand Prix series next year. 

"In the Olympic division at under-57kg, she will be in the top 15," her father said, confidently. As for her ambitions in the sport she is - naturally - looking over the eastern horizon toward the Tokyo in 2020.

But life will not just be taekwondo. She also hopes to go to university next year, though she is not yet clear on what her major will be. "Something sport related," she said. She also enjoys soccer and golf, but despite her good looks and weapons-grade physique, has no boyfriend.

In terms of techniques, she said: "I like my side kick as a base - but I like to do fancier kicks when I can." In terms of physique, her father reckons his daughter is perfectly engineered for the sport. "Her body is made for taekwondo: she is long and lean, she has fast-twitch muscles - she has all the attributes to succeed in taekwondo," he said. "And she can do all her techniques on both sides."

How about her mind game? Her father comes back with a surprising answer.

"Her mental game is weaker than more than 50 percent of the athletes - and that is part of the plan!," Park Sr confided. "Athletes that have a strong mental game at the beginning do not emphasise the physical so much, as they get away with using strategy. In my opinion, strategy can come later on, but if you don’t develop a physical base it is too late - the body only gives you a certain amount of time to develop; the mind can always develop."

"I’m excited to see how poomsae is growing," Munoz said. "There has definitely been a rise in competition over the past two years. I hope that poomsae will be included in the Olympics."

While there are, as yet, no indications that poomsae will get the Olympic nod, the growth was very clear to see at the 10th WTF World Taekwondo Poomsae Championships, in Lima, Peru, which boasted a record number of athletes and teams.

Munoz took gold in the individual freestyle – defending the gold medal she had won two years earlier. Having now won gold at two consecutive World Championships and many national titles, Munoz is now a well-established name in freestyle poomsae.

She trains six hours a day and is always pushing herself to improve. "I worked hard on jumping higher," she said. "I wanted to showcase getting comfortable in the air and not being afraid of going higher."

Munoz choreographs her own routines with her mother. Only then does she share them with her coach, Barbara Brand, to check what looks good and what does not - the end result is 80 per cent of her final programme comes from herself. This allows her to focus her routine on what she believes are winning elements such as soaring jumps and cartwheels - while making sure the routine is "practica" and not too "crazy".

Munoz believes it’s important there are effective fighting applications in her routine: "That’s part of tradition." But it is the freedom freestyle offers her that really attracts her to the sport. "Freedom to express yourself, with your music choice," she advised. "If you want the audience to feel something, you put in emotion."

At just 20, Munoz continues to hope that one day she will have the chance to express herself and light up the audience on the Olympic stage.

Her opponent on the day was The Netherlands’ Reshmie Oogink.

“I knew that Oogink was going to be a very complicated fight, I had never fought with her before,” Espinoza said. “But I wanted a lot to fight with her, I like to fight with the best!”

As the match got underway, Oogink proved herself unintimidated by Espinoza’s thunderous support and seized an early lead. Espinoza shot back with her patented overhand counterpunch, a technique that is rare in kick-heavy taekwondo, but which Espinoza has made her own.

But by the third round, the Dutch fighter was still ahead on the scoreboard. With the seconds ticking away, Espinoza launched an all-out attack, firing off a series of spinning back kicks in an effort to claw back points with the high-scoring, but risky technique.

It was in vain. She was unable to connect and the match ended 4-2, with Oogink taking the gold and Espinoza the silver. 

“I got a little disconcerted by the two points in the first round and physically I did not feel too good to overcome that obstacle,” the Mexican said in her post-match analysis.

Even so, winning silver at this elite level of competition is hardly anything to be ashamed of. “I am very happy with the result,” she said before conceding, “But I wanted gold.”

The 27-year-old is a national heroine in Mexico, with an Olympic gold from Beijing 2008, an Olympic bronze from London 2012 and the gold medal at the 2007 World Championships under her 2nd dan black belt.

Obviously competitive, Espinoza is a formidable presence. Striking looking - with wide, olive-skinned cheekbones and dark, fierce-looking eyes - she seems intensely focused, speaks emphatically and moves with grace and power.

In terms of physique, she admits that she is not as tall and leggy as many of her competitors, and her physique provides a clue to her fighting style: Espinoza is a power hitter.

So where does her famed counterpunch come from?

“I used to box when I was very young,” she said. That is where the technique comes from - she continues to hone it on the dummy - but she says she does not know where she got the timing to land it. It may be something to do with where she comes from: She hails from the same state as Julio Cesar Chavez, Mexico’s most famous boxer (a sport Espinoza no longer practices, but likes to watch).

Yet Espinoza is not a one-technique fighter. She also likes to use spinning back-kicks, and a chain of left-right-left-right turning kicks to the body - “bap-bap-bap-barrap!” in her own words. Asked to describe her personal style of taekwondo, she thinks for a moment before responding: “I am aggressive but I take care of points at the same time, I don’t lose control. I am very dangerous!”

Her year-round training includes circuit training and special physical training to strengthen legwork, such as kicking against an elastic restraint. Espinoza’s training encompasses both traditional and games-style taekwondo.

In the run-up to a competition, she downgrades the strength training and works more on speed and kicking “to feel light, relaxed and elastic”, while wearing the specific PSS to be used.

But her powerful style of taekwondo is not best suited to the current format, which favors light, touch contact off the front leg, she fretted.

“I have a little problem with the new [electronic scoring] systems compared to the old style; with any touch, the sensor makes points,” she said. “I am a strong kicker but normally the PSS system is not that strong; if you hit it too hard, it does not register.” However, she has seen how other competitors have adjusted to the changing sensitivities of the scoring system. “Other competitors have overcome that, they try to fix their problems to be acquainted with the system.”

Although she said she does not like appearing on TV and in newspapers, she is clearly a public figure.

During the photo shoot for this article, it proved difficult to get her out of the venue due to the dozens of Mexicans squealing “Maria!” and begging for signatures and photographs. She is sometimes recognised on the streets and in restaurants, and this high profile has won her corporate attention: Her sponsors include Coca Cola and athletic wear maker Under Armor.

And Espinoza is not just a warrior in taekwondo competition, she is the real deal: She is a private soldier with two-and-a-half years service in the Mexican Army, which provides full-time sport training for elite competitors, “as long as I am winning!”

As for the future, she hopes to possibly run a business or operate a string of taekwondo academies. The latter ambition seems feasible, given the sport’s popularity in Mexico.

Is there any particular reason why taekwondo is so popular in the country?

“The Mexican character is like saying,’ No Stop,’” she said.

“In boxing, there are many champions in Mexico and all the people want to be champions, all want to fight better. Taekwondo is the same.”

Chong's performance in the qualifying round had overcome all competitors. The Canadian's final performance was now just moments away. In the eye of the storm, he waited quietly for his cue to take position. The clock ticked.

The signal came. He bowed and paced to the centre of the competition area. The music began. As Chong exploded into his choreography of kicks, leaps and spins, the entire audience roared its excitement.

In just a minute-and-a-half, it was over. Chong, panting, waited as the scores were collated. Minutes later, the decision was declared: The Canadian was crowned the World Taekwondo Federation (WTF)'s first-ever world freestyle poomsae champion.

Freestyle poomsae is the newest addition to the repertoire of competition formats at the world championship level. It incorporates the traditional forms of poomsae with music, acrobatic skills, and artistic interpretation. The new format has grown in popularity in many WTF Member National Associations and was adopted as the newest competition discipline at the 2012 World Championships in Colombia after debuting as a demonstration event the previous year in Vladivostok, Russia.

Chong had been excited to learn about the addition of a freestyle division to poomsae competition.

"I have always been fascinated by that precision and power in the moves of poomsae, so to now be able to take that to the next level was really exciting for me," he said. "When my master and I heard of the news, we got to work trying things out and seeing what we could put together."

It was no easy task. The master-student duo agonised so much over Chong's routine that they were tweaking it on the eve of the World Championships.

"When we started training sessions and we saw the level of competition that I would face, we knew everyone had come prepared," Chong recalled. "My master and I decided we needed to up my level of difficulty, so three days before the compe- tition, we revamped my routine." That revamping went down to the line.

"Obviously the changes were worth it in the end, but it did mean a lot of late night training back at the hotel!" Chong said. "The night before competition I was training until after midnight."

The WTF's first ever world freestyle poomsae champion is not your typical youngster. He is a focused and determined individual who speaks deliberately, with careful consideration of the words he chooses. The discipline visible in his daily routine portrays a champion in training - not only in his sport but in his wider life as well. He is up at around 9am. and at the dojang by 2 pm where he prepares for his own training, as well as teaching the young kids that inspire him to forge ahead with his own dreams. In fact, his training often takes a backseat to his teaching, which he does not complete until around 10pm.

When asked about coaching he said, "The kids are really a driving force for me in my training," said Chong, who retained his world title in Bali in 2013. "They remind me of me when I was their age, so full of dreams of being a champion and so eager to train. Actually, I guess I am still that way, but the young students really keep me that way."

Is there pressure to be a role model for the students at his own dojang? "I don't know if the kids look at me that way; maybe they do," he replied with his characteristic quiet modesty. "I mean, they do know that I went to the World Championships, but I don't know if they give any meaning as to what it could mean. But there already is a kind of pressure to just be a good teacher. I hope I can have a positive influence in my life the way that my father did when I was growing up and that he and my coach have had in recent years."

Chong had two dreams when he was younger: being an Olympian and joining S.W.A.T, the elite police squad. He has clearly made his mark in the poomsae world and also competes locally in kyorugi. Meanwhile, alongside his training in taekwondo, he is working towards a career in law enforcement, having finished a two-year course in Police Foundations at Seneca College King Campus in King City, Ontario.

As fast as his kicks and spins may be, Chong chooses his words slowly and carefully before delivering them in a soft voice that is un- like that of many young men. He is a deliberate individual who is still planning his future.

He began taekwondo at the age of four when he was introduced to the sport by his father, a taekwondo master who helped to spread the sport at the grassroots level in Canada. When he was 13, his father moved the whole family to Toronto from Cambridge, Ontario, so that Charlie could have better training and his father could further develop his business. The decision to move paid off when he won that gold medal in Colombia.

So who is Charlie Chong? He is the standard that all others in the future of freestyle poomsae now have to live up to - himself included.
