高度分规则实施前、后世界蹦床网上个人项目比赛成绩变化特征研究

Study on Variation Characteristics of Final Results in Individual World Trampoline Gymnastics after F Rule

采用文献资料调研和数理统计对高度分规则实施前、后的2008年北京奥运会、2011年世界蹦床锦标赛、2012年伦敦奥运会和2013年世界蹦床锦标赛个人网上项目决赛成绩的D分、E分、F分和T分变化特征进行研究。研究表明,高度分规则实施后,蹦床网上男、女个人项目D分与E分不断提高,且2012年难度D分提高程度最大;女子项目动作完成质量E分的提高大于男子项目;高度分规则实施前,男、女项目T分与E分呈高度正相关;高度分规则实施后,男子项目T分与E分仍保持高度相关,但与D分、F分的相关程度有所提高;女子项目T分与F分呈高度正相关;两个项目的高度分呈波浪式变化,以男子项目提高显著。高度分规则实施后,蹦床网上男、女项目的发展变化不具一致性特征,但仍以提高E分、F分开始,最终实现D分、E分和F分的全面提高。

By literature review and mathematical statistics, this paper analyzes the variation characteristics of D.E. F and T of individual event （ 2008,2011,2012 and 2013 ） in trampo- line gymnastics after carrying out flying evaluation in order to understand timely the develop- ment of trampoline gymnastics in individual event. The results show that the score of both D and E is improved, the biggest improvement in D takes place on 2012 year for both events, the improvement in E for woman ~ s event is higher than man ~ s event after new rule ; before and af- ter rule, T is still significant correlation with E for man＇s event and the correlation with D and F to be improved. T is significant correlation with F for woman＇ s event After new rule, it likes the pattern of wave in F for both events and it is great changed significantly for man＇s event. The conclusion is that, after F rule, it shows different characters for trampoline individu- al, but the change to start is through the improvement in E, then in F, finally, in D, E and F.
