The training is part of the world governing body's efforts to ensure the highest level of officiating at next month's rearranged Olympics in Japan.

World Taekwondo has achieved gender equality with its referees, and 15 male and 15 female officials took part in the online sessions.

Presentations were given by Technical Commission chairman Inseon Kim on understanding the role of ethics in sport and competition, and by medical chair Dae Hyoung Jeong on COVID-19 protocols and recognising a medical emergency.

Referee chair Songchul Kim spoke on planning for various scenarios while technical delegate Phillippe Bouedo covered job descriptions for officials and the Olympic competition environment.

Mohamed Shaaban, the Games chair, spoke about the procedure for random weigh-ins and schedules.

A short introduction was made on the 4D replay system which will be used at the Olympics for the first time in Tokyo.

"At World Taekwondo we pride ourselves on the integrity, quality and consistency of our referees," said World Taekwondo President Chungwon Choue. 

"With the introduction of technological innovations to assist our referees in past years, we have aimed to remove human error from our competitions. 

"But we still rely on referees to make clear and objective judgements which allow our athletes to achieve the results they deserve.

"We have an excellent team of referees and just as at Rio 2016, we will once again have an equal number of male and female referees in Tokyo. 

"This is very important to us as we continue to set standards in gender equality and, through today's training, strive to raise the standards of officiating in taekwondo even higher."

A total of 130 athletes from 61 countries and the Refugee Olympic Team are due to compete in taekwondo at the Tokyo 2020 Olympics.

World Taekwondo said it would be attending an International Olympic Committee workshop on preventing the manipulation of competition tomorrow, as part of its "commitment to following the best practices for integrity in sport".
