The 23-year-old from Justinopolis, making his Olympic debut, took bronze in the over-80 kilograms heavyweight category.

He was only the second Brazilian to win an Olympic taekwondo medal following the bronze earned by Natalia Falavigna in the women's over-67kg heavyweight category at the Beijing 2008 Games. 

Siqueria beat the United States' 2011 Pan American bronze medallist Stephen Lambdin in the preliminary round before losing his quarter-final 6-1 to eventual silver medallist Abdoul Issoufou of Nigeria.

But he recovered his impetus in the repechage, earning a 5-2 win over France's M’bar N-diaye and then winning his bronze medal match against Britain's Mahama Cho 5-4.

The previous year, Siqueria had warmed up for his big Olympic moment by winning the Rio Open and taking bronze in the heavyweight class at the Summer Universiade in Gwangju, South Korea.

In 2017 he added a silver Universiade medal to his collection but in the World Championships that year he hit the barrier of Issoufou once again in the quarter-finals, with the Nigerian going on to take the heavyweight title.

Further significant medals came his way in 2018 as he won bronze at the Pan American Championships in Spokane and the Military World Championships in Rio.

In 2019 he regained his place on a global podium as he took over-87kg bronze at the World Championships in Manchester, beating home athlete Cho 15-12 in the quarter-final before losing 17-13 in the semi-final to eventual winner Rafael Alba of Cuba.

Shortly afterwards he added a bronze from the Pan American Games in Lima in the over-80kg category before winning the Sofia Grand Prix.

His only major competition before lockdown arrived in 2020 also saw him in the medals as he came second at the US Open in Kissimmee, Florida, losing to Mexico's world silver medallist Carlos Sansores.
