It was conducted by Alexandre Nascimento, who is head referee of the Ju-Jitsu International Federation (JJIF), while the Ju-Jitsu Asian Union organised the event.

"The seminar was very high quality and it was a great motivation for everyone who attended," read a JJIF statement.

"This is the first time that an official rules seminar of this kind has been held in Iran, and it is a big step forward for the sport in the country.

"We are very grateful to the National Olympic Committee of Iran for their support in making this event possible."

Achieving an increase in the number of referees and an improvement to their quality is at the forefront of the JJIF and JJAU's strategy to increase the sport's overall participation over the coming year.

As the organisation continues to grow, it is seeking to increase its pool of referees and is striving for the highest quality available.

The coming year is described as a pivotal one for the JJAU as it is featuring in a number of large events including the Hangzhou 2022 Asian Games and the Cambodia 2023 Southeast Asian Games.

"The number of refereeing courses should be doubled this year," said JJAU general secretary Fahad Al Shamsi.

"We are preparing for big events so we should prepare our members in the best way."
