Trampoline gymnastics (TRA) involves a series of skills performed at thrilling heights, across 4 different disciplines.
Inspired by safety nets beneath circus acrobats, gymnast George Nissen constructed the first trampoline prototype in 1934. Whilst it caught on quickly as a backyard activity, the first World Championships were not held until 1948, and was added to the Olympic programme in 2000.
Individual - Two routines are performed showing consistency of height, skill and minimum deviation from the centre of the trampoline bed.
Synchronised - The added challenge of timing, as two athletes perform the same routine simultaneously on adjacent trampolines.
Double-mini - A short run up on to a two-level mini trampoline to perform a rebounding skill before a dismount, on to a landing mat.
Tumbling - Gymnasts perform multiple somersaults and twists, down a straight track, showing control, skill and maintenance of tempo.
