| 摘 要： | 通过采用250f/s的高速录像分析法分别对三个小组27名国家竞走集训队员在两种不同速度的训练状态下的竞走技术进行详尽的运动学分析与对比,并结合前人的研究成果,认为竞走运动员加快竞走速度的主要手段应该以步长的发展为主,发展步频为辅,同时应该加大摆腿的速度耐力和转髋伸腿的专项训练,才能有效提高比赛成绩。

| Abstract: | In this study,the performances at two different walking velocities(normal,high) of 27 race walkers from national team was filmed with high-speed video at 250 Hz.The data were digitized and analyzed in APAS performance Analysis System.In conclusion,improving stride length should be the main method to get a higher walking velocity,instead of improving stride frequency.Meanwhile,walkers should strengthen the speed endurance of leg swing and reinforce hip rotating in order to get excellent performance. |
