【摘要】 通过对 8名第 6届世界田径锦标赛男子 2 0 0m决赛运动员的技术关键及速度结构特征的分析 ,表明 2 0 0m跑成绩的主要因素为后 10 0m的成绩 ,所以发挥和保持前 10 0m所获得的速度是技术关键。同时 5 0m - 10 0m间的时间与 2 0 0m成绩负相关 ,也是一个值得探讨的问题。更多还原

【Abstract】 We tend to study the key biomechanical characteristics and the speed arrangement at different stages of the running of the 8 final runners at the 6th world championship of Track and Field,and to provide theory reference for the trainning in man’s 200m-running in China.The study shows that the key technical factor of man’s 200m-running is the speed during the second 100meters,so it is vital to keep the speed obtained during the first 100meter,but the speed during the 50-100-meters affects the runner’s score negatively.更多还原
