摘　　要：采用文献资料法、测量法、数理统计法等对男子蹦床选手自选动作位移特征进行研究,分别从区域位移和落点位移两个维度进行讨论,在此基础上构建出位移的评价标准,并针对位移的特点和规则发展的趋向,试图找到科学、合理地评定位移的方法。主要结论为:蹦床位移分为区域位移和落点位移,位移的评定趋势是由区域位移向落点位移评分变革;区域位移提升了运动员自选动作成绩,成绩增长幅度在0.65-2.60分之间,对名次变化的影响达到70.83%;向后空翻动作的区域位移扣分明显高于向前空翻动作,833/、831<、813<、12101o、811<、803<等动作落点位移较大;男子自选套落点位移介于3.5-7.8m之间,平均值为5.7m,落点位移和名次之间存在一定正相关性;采用百分位法构建了区域位移和落点位移的单项评价标准。Using the literature method,measurement method and mathematical statistics method,this research takes the displacement characteristics of voluntary of men’s trampoline athletes as study object,respectively discusses two dimensions of area displacement and falling point displacement.On this basis,it builds the evaluation standard of displacement,and tries to find a scientific and reasonable evaluation method of displacement according to the characteristic of displacement and the rules of the development trend.The main conclusions are as follows:the displacement of trampoline is divided into area displacement and falling point displacement,and the evaluation trend is gradually varying from the former to the latter;the area displacement improves the performance of the athletes’self-selected movements,and the increase range of the performance is between 0.65 and 2.60 points,and the influence on the change of the ranking reached 70.83%;the area displacement deduction points of backflip is obviously higher than that of forward flip,and the 833/,831<,813<,12101 o,811<,803<are much larger in falling point displacement;the falling point displacement of the man’s self-selected suit is between 3.5-7.8 m,and the average value is 5.7 m,and there is a positive correlation between the falling point displacement and the rank.This study conducts a single-item evaluation criteria for the area displacement and falling point displacement.
