| 摘 要： | 选取李玲在2008年全国田径大奖赛萧山站女子撑竿跳高决赛4.45m夺冠时的比赛录像,运用德国SIMI Mo-tion影像解析系统进行分析,并与国内外优秀撑竿跳高运动员技术进行比较研究。研究结果表明：①李玲的最后两步助跑,倒2步步长偏短,且其倒1步比倒2步步长长,出现了＂拉大步＂现象。②李玲起跳时上手握点地面投影点和起跳点的间距较大,与现代撑竿跳高的技术要求略有偏差。③起跳的腾起角度、竿弦与地面的夹角较小,已达到世界级优秀运动员水平。④起跳时间偏长,插穴时间过早,与＂自由起跳＂技术尚有差距。⑤起跳步水平速度损失、垂直速度增加都较小,是比较合理的起跳技术,但最后两步助跑的水平速度不够。

| Abstract: | In this paper,a Simi motion image analysis is made on liling's pole-vaulting technique in the National Track and Field Championship held at 2008 in Xiaoshan,and do comparative study with the outstanding pole vaulting athletes at home and abroad.The results show that:(1) The length of Li Ling's last Step 2 is partial short,and the length of last step 1 is shorter than last step 2,it also appears pull big step phenomenon.(2) It have a greater distance between ground projection points of the grip point and Tak... |
