REUTERS: Focus on taekwondo at the 2020 Tokyo Olympics:
THE ABSOLUTE BASICS
* Taekwondo is a full-contact combat sport developed in Korea that means "the way of kicking and punching".
* Athletes, called taekwondoin, compete in three 2-minute rounds per match.
* 1 to 5 points are awarded for each strike to the torso or head, depending on the difficulty of the technique.
* Sensors inside the protective gear worn by athletes help with scoring.
HOW MANY MEDALS?
Eight gold medals are up for grabs across four weight categories each for men (-58kg, -68kg, -80kg, +80kg) and women (-49kg, -57kg, -67kg, +67kg).
WHAT HAPPENED IN RIO?
Jordan and Ivory Coast won their first-ever Olympic gold medals, in taekwondo. South Korea retook its top spot in the medal rankings, with two golds and three bronzes.
WHAT CAN WE EXPECT IN TOKYO?
Britain's Jade Jones and China's Wu Jingyu will be looking to make history by winning a record-breaking third Olympic gold medal in the sport.
A 4D camera will be set up, providing 360-degree views of the action. Coaches are given one appeal per contest to call for an instant video replay (IVR), although a successful appeal does not count against that quota.
WHEN IS IT HAPPENING?
July 24 to 27
WHERE IS IT HAPPENING?
Makuhari Messe, a convention centre in Chiba city, near Tokyo.
HOW DID WE GET HERE?
Taekwondo became dominant as a martial art form in Korea during the early 1900s. Its first two appearances at the Summer Olympics in Seoul (1988) and Barcelona (1992) were as an exhibition sport. It became a formal medal event at Sydney 2000 and has maintained that status ever since.
WELL, FANCY THAT!
In 2017, the sport's world governing body officially changed its name to World Taekwondo (WT) from World Taekwondo Federation (WTF) citing the negative connotations associated with the initials that had been used since 1973.
