对跳远运动员起跳腿不同高度跳深的实验研究

Research on the different Drop Jump Height of the Taking-off Leg of Long Jump Athletes

为探寻反应力量对跳远成绩的影响因素,本文以20名男子跳远专项运动员为实验对象,进行不同下落高度的单腿跳深的测力台实验。将采集、处理后的数据与跳远成绩进行的相关分析,实验结果显示:运动员的适宜下落高度(R=0.742,P<0.05)、适宜下落高度的F/体重/AB(R=0.788,P<0.01)与跳远成绩呈显著性相关关系。

In order to search the influential factors of reactive force to long jump performance, this paper research- es the take-off drop jump at different height of 20 male athletes＇ dynamometry experiment. And the results showed the appropriate drop height （R = 0. 742, P〈0.05） and the F of appropriate drop height/weight/AB （R = 0. 788, P〈0.01）have significant correlation with long jump performance.
