中外优秀男子跳远运动员跳远技术参数的回归分析

Attributive Analysis of Long Jump Technical Parameters between the Top Male Long Jumpers at Home and Abroad

通过采用参数均值的差异分析及显著性检验研究了中外优秀跳远运动员的相关技术参数,找出影响我国运动员与世界优秀运动员跳远成绩的主要因素,并运用多元回归分析建立回归模型,分析得出:绝对速度较慢,起跳角较小,起跳能力较差是影响我国运动员成绩提高的主要因素。

Through analyzing the differences between parametric means and testing the significance the antho research on the relevant rechnical parameters between the top male long jumpers at home and abroad,finds out main difference factors that affect their long jump grades.And then this paper builds attributive models by polu-attributive analysis,which shows that lower absolute speed,smaller takeoff angle and poorer takeoff ability are the main causes which influence the athletes' improving of grades in our country.
