摘要
通过信息技术及文献资料法,对我国男子优秀百米选手张培萌在2013莫斯科世界田径锦标赛上跑10 s时的全程节奏进行测量与分析,并与决赛的前8名选手进行比较。结果显示:1)张培萌步长较小、步频较高,属于步频见长型的选手,各分段步频与前8名选手各分段的最大值相近,本次跑法属于高步频的跑法;2)与前8名选手比,张培萌最高步频出现较晚,且仅维持一个分段。建议其从提高步长角度出发,以提高成绩。
Through the methods of information technology and documentation,Chinese elite sprinter Zhang Peimeng’s 100 m-run skill in semi-final at the 2013 IAAF World Champions was studied. The results show that Zhang’s running skill has the characteristics of short step length,high step frequency,as well as his split step frequency in each phase close to the top 8 sprinters’maximum value in correspondence phase in the final. Zhang’s peak step frequency turned out later than the top 8 sprinters in the final,and lasts only one phase. According to the results,we should focus on improving Zhang’s step length,which is helpful for him to improve his performance.
