膝关节转动速度及其与短跑速度的相关分析

A Study on The Correlation Between The Rotating Speed of The Knee Joints And The Running Speed of The Sprint

本文采用光电记时法对人体膝关节转动速度进行测定,并在此基础上对膝关节转动速度与短跑速度进行了相关分好。研究结果表明:(l)、两膝关节转动速度存在着明著的差异(p<0.01),(2)、膝关节转动速度在男女之间存在着明显的差异(p<0.01),(3)、膝关节转动速度与短跑速度存在着相关关系(r=-0.341—-5.38,p<0.01)。

By using the laser-electronic timing method,the auther of this paper measured the rotating speed of the knen joints and the running speed of the sprint,and also studied the correlation between them. The results show: 1)there are apparent differences in the rotating speed bet-ween tow knee joints,2)there are apparent differeces in the rotating speed of the knee joints between male and female,and 3)there are correlations between the rotating speed of the knee joints and the running speed of the sprint
