race walking; kinematics; stride length; stride frequency; vertical movement of centre
对影响和制约我国竞走运动员成绩发挥的因素进行分析和研究。研究发现,我国运动员"小步幅,高步频"技术风格依然存在。整体来看,我国运动员重心和头顶点垂直起伏较大,容易被裁判员判罚。我国部分运动员存在左、右腿力量分配不均衡现象,且上肢摆动幅度较小。

This paper analyzed the influence and restrictions on the sports performance of Chinese race walkers.The result shows that our athletes are still keeping the technology style which is called high frequency,and little stride.From the perspective of whole,the vertical movement of the centre and head of our athlete is larger and lead to be judged foul.Some of Chinese walkers have showed unbalanced distribution of left and right leg strength,and have small swing amplitude of arms.
