Trampoline & Tumbling
Trampoline and Tumbling is a sanctioned USA Gymnastics sport which consists of four disciplines, power tumbling, trampoline, synchronized trampoline and double mini trampoline. Unlike artistic gymnastics, athletes can pick and choose which events they would like to compete in. Trampoline was added as an Olympic Sport for the 2008 games and will be highlighted in this year's Olympics as well.
Power tumbling is performed on elevated spring runways that help tumblers propel themselves higher than a basketball goal as they demonstrate speed, strength and skill while executing a series of acrobatic maneuvers. Top-level contenders will perform explosive somersaults with multiple flips and twists.
A trampoline routine consists of 10 skills performed on a trampoline that is a far cry from the models that are found in many backyards. These modern trampolines can propel trained athletes as high as 30 feet in the air during performances! During two competitive routines, upper-level athletes easily demonstrate a graceful array of double, triple and twisting somersaults.
Double mini is a relatively new sport that combines the horizontal run of tumbling with the vertical rebound of trampoline. After a short run, the athlete jumps onto a small two-level trampoline to perform a rebounding trick immediately followed by a dismount element onto a landing mat. Double mini is similar in concept to springboard diving, using a mat instead of water.
