我国优秀男子1500m运动员各段落途中跑运动学特征研究

The Study on the Kinematic Character of the Way Run in Different Phases of the Elite Men 1 500-meter Runners in China

利用高速录像拍摄法、比较分析法、数理统计法等对参加2004年全国田径冠军赛暨大奖赛总决赛合肥站的我国优秀男子1500m运动员各段落途中跑的运动学特征进行了专题研究。结果表明:我国优秀男子1500m运动员各段落途中跑的运动学特征存在明显变形,主要表现在第二、三圈的平均速度明显低于第一、四圈的平均速度,这主要是由于我国优秀男子1500m运动员在第二、三圈支撑腿的缓冲时间延长、后蹬时间缩短所造成。

By the methods of recording the image at a high speed, comparative analysis and sports statistics, the kinematic character of the way run in different phases in the men 1 500-meter final in the National Big Prize Match of Track and Field held in Hefei in 2004,of those who are the elite men 1 500- meter players in China is analyzed.The result shows that the Chinese elite men 1 500-meter runners＇ average speed in the second and third lap is much smaller than that in the first and fourth lap.lt is because Chinese elite men 1 500-meter runners＇ supporting time becomes longer and the trampling time gets shorter that bring on their slower average speed in the second and third lap.
