Trampolining is one of the gymnastics’ disciplines in which athletes perform acrobatics while bouncing on a trampoline. The skills performed by the gymnasts are a combination of movements like somersaults, body landings, shaped bounces and twists performed in positions as the tuck, pike or straight position. In 1936,George Nissen constructed the first folding trampoline in his garage and named it by modifying the Spanish word "trampolin" for the springboard. The first national championship of the sport took place in 1948 in the USA and was included in the Pan-American Games in 1955. In 1999, the sport became a discipline of the FIG and was included in the Olympic Games in 2000.
The trampolining routines are performed on trampolines providing good control in the jumping zone and rebound properties that generate the height needed for aerial manoeuvres. It consists of a flexible jumping area and protective paddings around the bed for protection against injuries. The performance area for double mini trampoline includes a runway, a trampoline and a landing area. Tumbling event takes place on a long spring track known as tumbling track which is usually 25-meter in length.
