| 摘 要： | 对我国优秀男子110m栏运动员刘翔等人第五栏腾空过栏的技术动作分三次进行定点、定焦距、高速拍摄,采用影片数字化、数据平滑处理和运动生物力学计算机辅助解析和辅助教学系统软件解析以及体育统计等方法,通过分析刘翔等人第五栏腾空过栏技术的两维图像,运用生物力学理论将解析出的刘翔两次比赛的阶段性参数相比较,并与三次拍摄的其他可解析运动员的技术参数对比。解析结果表明:(1)刘翔两次比赛第五栏中腾空过栏时的躯干前倾性大,两腿最大夹角大,腾空时间短,腾空过栏的速度快。(2)刘翔两次比赛第五栏的跨栏步步长小,起跨攻栏距离与下栏着地距离之比非常接近理论上的最理想比例。

| Abstract: | The fixed point,fixed focus and high-speed photo taking were used and with the adoption of photo digitalization,data smooth dealing,Sbcas2 and sports statistics,this research analyzed the two quotas resulted from the photo images of Liu Xiang's fifth stride skill taken by a digital cameral(JVC9800,made in Japan).Comparative analyses were made between Liu Xiang's quotas and those of the other athletes. The result revealed that when taking the fifth stride,Liu Xiang had a strong hurdle attacking will.The time of resistance was short.The starting angle was small and the landing angle was big.Moreover,the speed of clearance was fast,causing little weight point changel. |
