The idea of taekwondo is simple - kick and hit your opponent as often as possible in three rounds lasting three minutes for men, and two minutes for women.
Since the point is to strike your opponent a lot, competitors wear lots of different bits of padding.
A point is earned if a hit on a person's body is achieved, but two are awarded if it's the face or head that gets hit.
However, there are strict rules on which bit of your body you are allowed to use to hit your opponent, like only the feet can be targeted at someone's head.
Bouts can also be won by knockout, with a 10-count from the referee determining a KO.
Unusually, if bouts are level on points, the winner is decided by who, in the referee's opinion, did the most attacking.
