Roller sports are sports that use roller skates or similar. Roller skating is where the athlete travels on smooth terrain with roller skates as fast as possible when racing.
Skates come in two basic varieties quad roller skates which have 4 wheels two either side of the boot and inline skates which have 4 wheels inline down the middle of the sole of the boot.
This means there are different events for the different skates such as speed skating, roller derby and aggressive skating.
Other sports can also be played on skates for example roller hockey. This category of sports can also cover other events such as skateboarding as it involves wheels.
Roller Sports were incorporated into the Asian Games in 2010.
