Trampolining or trampoline gymnastics is a competitive Olympic sport in which athletes perform acrobatics while bouncing on a trampoline. 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. Outside of the Olympics, competitions are referred to as gym sport, trampoline gymnastics, or gymnastics, which includes the events of trampoline, synchronised trampoline, double mini trampoline and tumbling.
