According to the regulations of Paralympic Games, athletes who have amputated in track and field events can wear artificial limbs in the competition. This kind of prosthesis is mainly made of carbon fiber, which is strong and light, and looks like the hind legs of a cheetah, so it is also called the "blade" prosthesis.
