Taekwondo is a sport of hands-and-feet fighting.
The athletes use only their hands and feet. They kick very fast.
They must wear special clothing to avoid getting hurt.
Taekwondo athletes are put into different groups depending on their body size. This is so a very big person cannot fight a very small person.
It takes many years of training to do taekwondo.
A form of taekwondo started 2000 years ago in Korea. The Sydney 2000 Games will be the first time taekwondo has been an Olympic sport.
