【摘要】 采用测量、数理统计、比较等方法,探讨少年田径运动员身体重心高度、身高、下肢长A等指标在不同生物年龄段的变化特征及各指标间的内在关系。结果表明,少年田径运动员身体重心相对高度与下肢长A/身高×100%指数基本上是随着生物年龄的增长而下降,身体重心绝对高度、身高、下肢长A年增长值总体的变化趋势较为一致;少年男、女田径运动员身体重心绝对高度与身高、下肢长A之间为高度相关,身体重心相对高度与下肢长A之间为不相关。更多还原

【Abstract】 Through using the method of measurement,mathematical statistics and comparison,this paper discusses the height of body weight center,body height and lower limb’s length of junior athletes at difference biologic ages and their relations.The result shows that the relative height of body weight center and indexes of lower limb’s length and stature is almost contrary to biologic ages,while the absolute height of body weight center and indexes of lower limb’s length and stature is in similar direction basically with the total changing tendency.There is highly correlation between female and male athlete’s body weight height,lower limb’s length,while there is no correlation between body weight height and lower limb’s length.更多还原
