Trampoline events involve athletes using trampolines that can propel them up to 30 feet in the air, during which they can perform double and triple twisting somersaults. Tumbling utilizes elevated rod-floor runways that enable athletes to jump at heights more than 10 feet and execute a variety of acrobatic maneuvers. For the double-mini competition, the athlete makes a short run, leaps onto a small two-level trampoline, performs an aerial maneuver and dismounts onto a landing mat. Trampoline was added to the Olympic Games in 2000, and at the 2012 Olympic Games in London, the USA had its first athlete in history advance to the finals. 012 Olympic Games in London, the USA had its first athlete in history advance to the finals.
