International Trampoline Federation
The Fédération Internationale de Trampoline (FIT; English: International Trampoline Federation) was an international governing body of competitive trampoline gymnastics from 1964 to 1998. The organization was created after the first World Championships for the sport in 1964, during which the sport did not have a governing body.
