Rudolf Spieth proposes that the FIG should include Trampoline as an FIG discipline. The FIG votes 11-1 to reject the proposal, suggesting that “This is not an attractive apparatus for female gymnasts.” How wrong they were. Where the decisions in 1954 had left the door open for trampoline, this effectively closed it.
This action sent George Nissen looking for other ways to promote trampoline internationally and eventually led to the creation of the FIT 3 years later. This decision also had repercussions for rules and scoring. In the US, trampoline continued alongside gymnastics, and there the inclination was to keep the scoring systems similar. However, internationally, the competitive rules were now independent of one another.
Friction continues between the US College Coaches (NACGC) and the AAU. From the perspective of the college coaches, AAU did little to develop the sport of gymnastics, did not really know the sport or the coaches, and yet was intimately involved with team selection and coach selection for international events. More information on the conflict between the college coaches and AAU is available on the USAG History Timeline. A good summary is also available from Grossfeld (2010).
