| 摘 要： | 运用文献资料、数理统计、调查法等方法,以参加2009年全国竞走大奖赛的男子50km竞走项目的42名运动员为研究对象,从运动员的地域分布特征、竞技年龄特征、速度分配与成绩特征、运动员的技术特征等方面分析其竞技现状。研究表明:我国50km竞走运动员人数区域分布不均匀,主要分布在云南、山东、辽宁等省份;运动员的竞技年龄呈现"年轻化"的趋势;运动员的速度曲线变化幅度较大;运动成绩与北京奥运会前8名的成绩相比差异显著;我国运动员小步幅,快频率,高重心,起伏大,髋关节转动小,走的拘束、紧张等技术问题没有太大改观。

| Abstract: | Through using the method of literature review,mathematical statistics and investigation,taking the 42 athletes participating in men’s 50km race walking in 2009 National Race Walking Grand Prix as research subject,this paper analyzed their competitive strength from the aspects of regional distribution,athletic age,the characteristics of their speed distribution and performance and the characteristics of their competitive techniques.The result shows that regional distribution of athlete numbers being uneven,that mainly in the provinces of Yunnan,Shandong and Liaoning.The athletic age shows a "younger" trend,and variation range of athlete’s speed curve being big.The difference between their performance and that of the top 8 walkers in 2008 Beijing Olympic Games is remarkable.Chinese athletes’ competitive techniques including small stride,high frequency,high center of gravity,big fluctuation,small movement of hip joint and stress in walking still remain unchanged. |
