摘要
以参加2006年全国室内田径锦标赛女子撑竿跳高比赛的12名运动员技术为研究对象,采用高速录像等研究方法,对比赛时所表现的起跳技术进行运动学研究。研究表明,我国优秀运动员起跳时水平速度损失较高;起跳时间与世界优秀水平接近;起跳点与上握点的位置基本符合现代撑竿跳高技术的要求;起跳蹬地角与优秀运动员还有一定差距,重心腾起角较大;起跳时肩角未充分打开;起跳时膝关节弯曲度稍大。
The paper pats a research on 12 athletes in women＇s pole vault competition of 2006 National Indoor Track and Field Championship and tries to find out the reason for this. By using high- speed recording camera to record and analyze the techniques of take - off from the point of kinematics. The results show： the heavy loss of horizontal velocity of excellent women pole vault athletes, their taking- off time is close to world excellent level; their pole- holding section and taking- off spot basically meet the requirements of modem pole vault; the taking - off still lag behind world excellent players, the jumping angle . of body gravity is relatively big, humeral angle is not wide enough and the bend angle of knee joint is big when taking- off.
