山东省优秀男子竞走运动员动作技术诊断

Technical diagnosis of elite male race walkers of Shandong

本研究选取11名现役山东省优秀男子竞走运动员为研究对象,使用二维高速摄像,采用APAS和Dartfish动作解析软件对竞走动作进行定量分析。发现山东省多数运动员速度损失率和身体重心及头顶垂直位移波动较大,但离地踝角和踝关节角速度较为合理。少数运动员髋关节伸展不充分,导致步频过快,步幅过小。

The technical diagnosis of 11 elite male race walkers from Shandong province was made with 2 - D captures to monitor their motion, and also the software of APAS and DARTFISH was used to make the quantitative analysis for them. Through the motion analysis, we found that the most speed loss rate of Shangdong elite male race walkers lost much and the displacement of head and center of gravity ankle and the ankle angle from the ground shifted too much, but their angular velocity of the are in reason. A few athletes have a small max hip angle, which conducts a faster race pace and shorter step length.
