Taekwondo is a martial art developed in Korea which debuted at the Olympics at the Seoul 1988 Games.
It's one of👍 the Olympic sports that have mainly been dominated by Asian nations, but recent Games have witnessed exciting shifts and upsets.
The👍 universality of the sport is no longer in question with taekwondo athletes, or taekwondoin, from Cote d'Ivoire to Jordan clinching👍 historic gold medals at Rio 2016, and team Great Britain showing talent is abundant in Europe.
There are several taekwondo styles.
World👍 Taekwondo oversees the Kukkiwon-defined style of taekwondo that is commonly referred to as Olympic taekwondo.
Olympic taekwondo allows the use of👍 a very small number of the total number of techniques.
From the basics to the equipment, here's a rundown of taekwondo👍 rules, scoring and the different belts.

Equipment and facilities Taekwondo is a combat sport between two👍 fighters in the same weight category.
The centre of the competition area is octagonal-shaped and measures 8m in diameter.
Contestants must wear👍 a dobok or a white competition uniform.
Additionally, they must have a trunk protector, head protector and, for male athletes, a👍 groin guard that is worn under the dobok.
The taekwondoin must also be equipped with forearm and shin guards, gloves, sensing👍 socks, and a mouth guard before entering the competition area.
Head protection is usually firmly tucked under left arms when entering👍 into the competition area and is worn when instructed by the referee.

Belts Taekwondo athletes👍 also tie a coloured belt around their waist.
The colour signifies the competitors' ranks in their sport.
The belts range from white👍 to black belts.
The belt system is divided into 10 grades, or gup, and nine degrees (dan).
Grades start from white for👍 beginners, through to yellow, green, blue, red and the highest is black.
The black-belt holders, who are the most experienced, are👍 further graded as 'dan' from the first degree up until the ultimate ninth level.

The basic rules👍 - foot and fist The rules of taekwondo as outlined by World Taekwondo require a standing bow to the referee,👍 followed by a bow to the opponent, before matches.
All matches last over three rounds of two minutes each, with a👍 one-minute break between rounds.

Taekwondo aptly means 'the👍 way of the foot and fist', to correspond with the blows and kicks that score points.
The objective of each competitor👍 is to score points by landing blows and kicks on their opponent's torso or head or to win by knockout.
Blows👍 must be delivered through a straight punching technique using the knuckle part of a tightly clenched fist.
The kicks that count👍 are those delivered using any part of the foot below the ankle bone.
Scoring Scoring of a valid point or points👍 is determined primarily using the electronic scoring system installed in the head or trunk protectors, known as the Protector and👍 Scoring Systems (PSS).
Points awarded for punching techniques and additional points awarded for turning kicks are scored by judges using manual👍 scoring devices.
The valid points are: One point for a valid punch to the trunk protector
Two Points for a valid kick👍 to the trunk protector
Four points for a valid turning kick to the trunk protector
Three points for a valid kick to👍 the head
Five points for a valid turning kick to the head
One point awarded for every penalty (known as gam-jeom) given👍 against the opponentTaekwondo explained
Penalties and prohibited acts The only penalty in taekwondo is a gam-jeom.
A gam-jeom is declared when an👍 athlete punches to the face, or punches or kicks below the waist.
Also not allowed is attacking an opponent with the👍 knee or the head.
Athletes are penalised if they use their leg to block or kick their opponent's leg to prevent👍 a kicking attack, have their leg in the air for more than three seconds to impede an opponent's potential attacking👍 movements, or if a kick is adjudged to have been aiming for below the waist.
Taekwondoin lose points for crossing the👍 boundary line with both feet, falling to the ground, avoiding or delaying the match, and for pushing or grabbing their👍 opponents.
Falling to the ground is penalised in taekwondo.
Contestants also have to watch out how they deliver their kicks to the👍 trunk PSS, as one can lose a point for attacking with the side or bottom of the foot while the👍 knee is pointed out in clinch position.
Attacking a fallen opponent is also prohibited.
Any misconduct or unsportsmanlike behaviour of the contestant👍 or their coach can cost a point.
Key decisions Golden Point Round [GDP]: For drawn matches, the contestants go for a👍 golden point round.
This is sudden death as the first to score wins.
An athlete can be awarded the match if their👍 opponent picks up two penalties in the golden round.
If a match goes to golden point, all scores awarded during the👍 first three rounds are not considered.
Win by superiority [SUP]: If neither of the contestants has scored two points after the👍 golden round, the winner shall be decided by superiority based on the contestant who received a point by a punch👍 in the golden round, or the contestant who got a higher number of hits registered by the PSS during the👍 golden round or the one who won more rounds in first three rounds.
If the athletes were tied on points the👍 one who received fewer penalties during all four rounds wins the match, and if they were tied on penalties the👍 referee and judges shall determine superiority based on the content of the golden round.
Point Gap [PTG]: A win by point👍 gap is when there is a 20-points difference between two athletes at the end of the second round and/or at👍 any time during the final round.
Referee Stops Contest [RSC]: The referee can stop the match if the contestant has been👍 knocked down by an opponent's legitimate technique and cannot continue the match, or to protect a contestant's safety.
The medical commission👍 can also call off a match due to a contestant's injury.
A Referee can stop a contest off if an athlete👍 is injured.
