Trampolining is a sport where stunts are performed on a trampoline. A trampoline consist of a bed of solid material that is suspended from a steel frame by steel springs. Legs about one meter high support the trampoline.
The elasticity of the trampoline allows a person to bounce to considerable heights. Some competitors bounce as high as 6 meters and twist and somersault before landing.
Trampoline dates back to the 1930s when an American named George Nissen developed the forerunner of the modern trampoline in his garage.
The first world championships in trampolining were held in the 1960s.
