| 摘 要： | 主要采用高速录像拍摄法,对参加2004年全国田径大奖赛暨总决赛(合肥站)的我国优秀的男子1500 m 运动员李炎各段落途中跑的运动学特征进行分析研究。结果发现:与世界优秀的男子中长跑运动员 Sebastian Coe 相比,李炎第二圈和第三圈的平均步长存在较大差距是李炎成绩落后 Sebastian Coe 的主要原因;李炎维持高速跑的能力较差;在全程的单步时间和步频上,李炎同世界优秀的中长跑运动员 Sebastian Coe 之间没有显著性差异;李炎途中跑技术的运动学特征存在着较大变形。

| Abstract: | By the method of video analysis,kinetic characteristics of Li Yan's running in different segments of a 1500m competition were studied.The result shows that compared with Sebastian Coe, world's top long and middle-distance runner,Li Yan's average pace length in the 2nd and 3rd laps is shorter than Sebastian Coe.And this is the main reason for his falling behind.Li Yan's ability of high speed running is at a relatively lower level.There is no significant difference between Li Yan and Sebastian Coe in terms of single pace and pace frequency in the full distance.Fluctuation of the kinetic characteristics of Li Yan's intermediate running technique can be noticed. |
