During a trampoline competition, athletes need to complete prescribed actions and optional actions. In the trampoline event, a player needs to perform 3 different sets of actions. The first set of actions is the prescribed action routine, and only the "difficulty points" of two of the actions are calculated. The second and third sets of actions are optional action routines.
The score components of a trampoline routine are divided into "technical points", "difficulty points" and "synchronization points". "Technical points" are used to evaluate the completion of athletes' movements, with a full score of 10 points.
In the official trampoline individual routine, there are five "technical judges". They will evaluate the "technical points" on the spot according to the athlete's completion. The sum of the three "technical points" in the middle is the total of the set of movements. "Technical points".
Another main component of the trampoline routine is the "difficulty score". The calculation of the "difficulty score" is mainly determined by the number of flips of the action, and the "difficulty frame" The "difficulty score" of the world's top athletes can reach about 17-18.5 points during training. In the 2004 Canadian Championships, the difficulty score was 18.5 points. " "Difficulty score" plus "technical score" are the final score of a trampoline athlete in his personal routine.
