短跑运动员王能希髋摆动技术改进对百米成绩的影响

Effects of the Improvement of Wang Nengxi's Hip Swing Technique on His 100M Sprint Performance

采用文献资料法、实验法和对比分析法等研究方法,通过对现役运动员王能希的历时两年跟踪调查研究,拍摄其途中跑的影像资料并进行解析,取得其运动学数据。通过对比分析数据的变化来剖析髋关节摆动技术对短跑成绩的影响。

Sprint technique has been developing for quite a few years. More and more attention has been paid to hip swing technique by the coaches and athletes. With the methods of literature study, experiment and comparative analysis, the author made a two-year follow-up survey of the active sprinters. Videos of their running were taken for analysis so as to obtain kinematic data. Comparative analysis is applied to analyze the changes of the data in order to find out the effect of hip swing technique on the improvement of sprint performance.
