不同水平女子100米栏运动员跨栏步的运动学分析

Kinetic Analysis of Hurdle Clearance for Women's 100m at Different Competitive Levels

通过高速摄影和文献资料法，对不同水平女子１００ｍ栏运动员分析，发现高水平运动贞起跨时的起跨距离、身体重心的水班平速度明显优于水平相对低的运动员；腾空过栏时低水平运动员身体重心的垂直位移明显大于高水平运动员的值；下栏着地时高水平运动员身体重心水平速度的损失率明显小于低水平运动员；并且发现不同水平运动员的起跨距离、起跨时身体重心水平速度、腾空时身体重心垂直位移、下栏着地时着地点与身体重心垂直投影点的水平距离等指标与其身体重心平均水平速度呈高度正或负相关。

Using video techniques to study the hurdle clearance at different levels of performance in female's 100m.This study showed that the better female group performed with a greater take-off distance, a greater horizontal velocity of CM, a lower vertical distance of CM and a greater landing horizontal velocity of CM than the lower level female group. Also, correlate analysis of mean horizontal velocity of CM VS take-off distance. Vertical distance of CM etc. variables within different groups, and there were significant correlation. However, it was important to increase the number of subjects studied at different levels of performance to improve statistical validity. Furthermore, the demands placed on the athletes with different anthropometrics compositions should be addressed in future research.
