A Study on the Change of Trampoline Rules Influencing the Results and Rank——Taking the 30th London Olympics Male Trampoline as an Example

With the methods of literature research,video observation,mathematical statistics and so on,this paper made a comparative study on the competition results of 16 male trampoline athletes who participated in 2012 the 30th London Olympics Games.The study shows that from the movement difficulty coefficient,movement quality and flight time,Chinese male trampoline athletes have reached the advanced level in the world,which makes up of the three top countries with Russia and Japan.In preliminary,the results of the first and the second action sets depend on the movement quality and height.The movement quality and space-time synergy are in positive correlation.The more elite male athlete one is,the higher the movement difficulty coefficient is,the better the movement quality is,and the higher the movement flight is.The potential winner should challenge a higher level in movement coefficient.The key factors of keeping Chinese male trampoline athlete's advanced competition level are to pay attention to the developing trend in trampoline,the balance of the movement quality and flight time based on some difficulty coefficient.
