摘要
本研究以参加2007年在广东省肇庆市举行的全国田径大奖赛女子三级跳远决赛前8名运动员作为研究对象,将三跳中与运动成绩密切相关的运动学指标作为研究内容,对其运动技术进行解析研究,并与世界选手进行比较。结果表明:我国运动员上板速度较小,第一、二跳速度保持能力差;专项能力差,不能很好地控制三跳的比例,这是造成我国女子三级跳远成绩落后的主要原因。
This research takes as its research subject the top the National Track and Field Grand Prix held in Zhaoqing city of eight Chinese jumpers of women＇s triple jump finals in Guangdong Province in 2007. It researches kinematical indexes closely related to the performance of triple jumpers and makes a comparative study between the kinematic technique of the top eight Chinese jumpers and that of world jumpers. Research findings indicate that the step - onto - the - board speed of Chinese jumpers is comparatively low and so is the ability to maintain the speed of the first and second jumps, and their professional competence is poor and they cannot well handle the ratio between the three jumps. Those are the reasons why Chinese women jumpers have poorer performance.
