摘要
采用文献资料法、数理统计法、因子分析法,对第11~13届全运会我国男子十项全能优秀运动员成绩进行了因子分析与线性回归分析。研究认为:“下肢爆发因子”、“上肢力量因子”与“跑步耐力因子”是影响我国男子十项全能运动员运动成绩的3个主因子,并将成绩总分作为因变量,3个主因子中载荷值大于0.7的主要影响指标因素作为自变量进行了多元线性回归分析,结果表明,对我国男子十项全能运动员总分影响从大到小的单项分别为:铅球、110米栏、铁饼、1500m跑、100m跑。
Using the methods of literature, mathematical statistics and factor analysis, this paper analyzes the performance of Chinese Men's Decathlon elite athletes in the 11th ~ 13th national games by factor analysis and linear regression. Study shows:“the lower extremities burst factor”,“upper body strength factor” and “running endurance factor” are the three main factors of affecting the athletic performance of Chinese Men's Decathlon athletes. Take the total score as the dependent variable and Take the three main influencing factors that the principal factor loading value > 0.7 as independent variables, performing multivariate linear regression analysis. The results show that the influence on the total score of Chinese Men's Decathlon athletes is as follows: Shot put, 110m hurdles, discus, 1500m, 100m.
