| 摘 要： | 运用文献资料法、数理统计法等方法,对近二十年中外优秀男子100米运动员的身高、体重、克托莱指数、步长、步长指数、步频、步频指数等多项基本参数进行比较分析。结果表明:成绩较好的A组和成绩较差的B组比较,两组运动员的成绩存在显著性差异(p<0.01),两组运动员的身高、体重、克托莱指数均不存在显著性差异(p>0.05),但是成绩更好的A组运动员的身高、体重、克托莱指数3项参数的平均值均大于B组;世界优秀男子100米运动员各项基本参数均优于我国优秀男子100米运动员。

| Abstract: | By means of literature material and mathematical statistics,the paper analyzes various basic parameters of Chinese and foreign top 100m runners in the recent 20 years in terms of their height,weight,Quetelet index,step length,step length index,stride length,stride length index and so on,with the result showing that by comparing Group A(with better results) with Group B(with poorer results),a significant difference in their results can be witnessed(p < 0.01),and there is no significant difference(p > 0.05) in the runners of both groups in their height,weight and Quetelet index,but the runners in Group A with better results show a bigger mean value in height,weight and Quetelet index than that in Group B.The basic parameters of the world top 100m runners are better than those of Chinese runners. |
