中国青少年蹦床网上个人项目的发展态势研究

Research on the Development of Individual Trampoline Events in Chinese Youths

为探究中国青少年蹦床网上个人项目的发展态势,运用文献资料法、数理统计法、对比分析法等研究方法,对2005—2020年国际蹦床评分规则和中国青少年特定规则进行了归纳与分析,对中国青少年蹦床网上个人项目得分要素及其与成绩之间的关系进行分析。研究表明:(1)技术、难度、高度、位移是得分要素。(2)技术与成绩关联度始终处于第一位,其中在女子比赛表现为逐届下降趋势。(3)难度与成绩关联度逐届减弱,男女表现有所不同,分别处于第二位和第三位。(4)高度与成绩关联度呈逐步上升的态势,其中在女子赛事中表现更为明显,男女分列第三位和第二位。(5)位移与成绩关联度呈现反“抛物线”趋势。(6)前三名运动员与完成决赛的其他运动员相比,技术、高度和位移差距逐届缩小,难度差距逐届增大,女子表现尤为明显。

In order to explore the development of individual trampoline events in Chinese youths,using the methods of literature,mathematical statistics,comparative analysis,etc.,this paper sums up and analyzes the international trampoline scoring rules and the special rules for Chinese youths from 2005 to 2020.This paper also analyzes the relationship between the scoring factors and the achievements of Chinese youthtrampolinists.The following conclusions are drawn:1.Technique,difficulty,height and displacement are the key factors of scoring.2.The correlation between technology and achievement is always the most significant,with the correlation for females declining.3.The correlation between difficulty and achievement decreases gradually,with its significance different for males and females,in the second and the third place respectively.4.The correlation between height and achievement is on the rise,in the third and second the place for males and females respectively.5.The correlation of displacement and achievement shows an anti-parabola trend.6.Compared with other athletes who finished the final,the gap of technique,height and displacement of the top three athletes gradually decreases,and the difference of difficulty gradually increases,especially for females.
