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.
Trampolining is a competitive gymnastic sport. One performs a routine of complex combinations of somersaults and twists making only 10 contacts with the trampoline bed. There are three main positions in which rotations can be performed; pike, tuck and straddle. One can land on their; feet, front, back or in seat position.
