Trampolining

Trampolining is a competitive Olympic sport in which gymnasts perform acrobatics while bouncing on a trampoline. These can include simple jumps in the pike, tuck, or straddle position to more complex combinations of forward or backward somersaults and twists.

Outside the Olympics trampolining also includes the events of synchronized trampoline, tumbling (or power tumbling) and double mini-trampoline.

In the early 1930s, George Nissen observed trapeze artistes performing tricks when bouncing off the safety net. He made the first modern trampoline in his garage to reproduce this on a smaller scale and used it to help with his diving and tumbling activities. He formed a company to build trampolines for sale and used a variant of the Spanish word trampolin (diving board) as a trademark. He used the trampoline to entertain audiences and also let them participate in his demonstrations as part of his marketing strategy. This was the beginnings of a new sport.

In the USA, trampolining was quickly introduced into school physical education programs and was also used in private entertainment centers. However, following a number of injuries and lawsuits caused by insufficient supervision and inadequate training, trampolining is now mostly conducted in specialist gyms with certified trainers. This has caused a large reduction in the number of competitive athletes in the United States and a consequent decline from the earlier American prominence in the sport. Elsewhere in the world the sport was most strongly adopted in Europe and the former Soviet Union. Since trampolining became an Olympic sport in 2000, many more countries have started developing programs and China's program developed World Champion athletes in less than a decade.

Competitive trampolining routines consist of combinations of 10 contacts with the trampoline bed combining varying rotations, twists and shapes with take-off and landing in one of four positions:
