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.
There are three related competitive rebound sports, synchronized trampoline, tumbling (or power tumbling) and double mini-trampoline.
