Tumbling, sometimes referred to as power tumbling, is a gymnastics discipline in which participants perform a series of acrobatic skills down a 25 metres (82 ft) long sprung track. Each series, known as a pass, comprises eight elements in which the athlete jumps, twists and flips placing only their hands and feet on the track. Tumblers are judged on the difficulty and form of their routine. There are both individual and team competitions in the sport.
Trampolining or trampoline gymnastics[1] is a recreational activity, acrobatic training tool as well as a competitive Olympic sport in which athletes perform acrobatics while bouncing on a trampoline.[2] In competition, these can include simple jumps in the straight, pike, tuck, or straddle position to more complex combinations of forward and/or backward somersaults and twists. Scoring is based on the difficulty and on the total seconds spent in the air. Points are deducted for bad form and horizontal displacement from the center of the bed
