A large, thick mat, known as the safety platform, is on the floor at each end of the trampoline. It will cushion the impact if an athlete falls from the trampoline.
Men wear a sleeveless body suit and long gym trousers while women wear a tight body suit with sleeves that covers at least 2/3 of their arms. Athletes wear socks or special shoes designed for the trampoline.
The athletes jump, tumble and somersault on the trampoline. Each trampoline routine consists of 10 exercises.

History
The first modern trampoline was built by George Nissen and Larry Griswold around 1934 at the University of Iowa in the USA. It was designed as a training place for gymnasts, divers and freestyle skiers all of whom needed to practise their acrobatic skills.
Trampolining became an Olympic event at the Sydney Games in 2000.
