摘　　要：本文采用文献研究法、三维录像解析法和统计分析法对第11届全运会女子铅球决赛前八名运动员最好成绩投次进行关键运动技术研究,获取她们的部分关键运动学参数,同时和世界级优秀运动员的相应参数进行比较分析,得出相应的研究结果。本论文的主要研究结论为1.背向滑步转身跳投技术按整体动作结构可分为后摆、滑步、过渡、双支撑和最后出手投掷五个阶段。2本研究再次证明了出手速度与比赛成绩呈高度正相关,相关系数达到0.95。而出手角度和其他运动学参数与成绩呈中低度相关。3.本届全运会中冠军巩立娇6次试投平均成绩为19.60±0.46m;平均出手速度为13.47±0.24m/s,与世界级选手接近;平均出手角度为33.99±1.23°,低于世界级优秀运动员;平均出手高度为2.03±0.03m,距离抵制板的水平距离平均为-0.03±0.08m。4.前3名运动员李玲、李梅菊和巩立娇最好成绩投次质心最大分别为速度为2.84m/s、2.65m/s和2.91m/s,质心最大速度与成绩相关性不大。铅球的出手速度为12.69m/s,13.31m/s和13.84m/s,出手角度为38.5°、35.5°和33.9°,铅球的出手高度为2.09m、1.98m和2.06m。By using the methods of documentary and the 3-D video analysis and the statistics methods,the key sport technique parameters of women shot-put athletes had been researched,who ranked in the top 8 in the 11th National game in 2009,some key kinematical parameters of them were got and received.In comparison with the same world-class women shot-put athletes＇ parameters,it can deduce interrelated investigative results.The main conclusions are as follow： 1） the back glide shot-put technique can be divided 5 phases named back-swig leg,glide foot,transit foot,two supports and the last release.2） The correlation between the release velocity and the achievement is confirmed high correlative level again.The correlation coefficient is 0.95;and the between of the release angle and kinematical parameters and the achievement is moderate or low correlative level.3.the average competitive result of the championship named GONG Li-jiao is 19.60±0.46m,the average release velocity is 13.47±0.24m/s,closing to the world-class players;the average release angle is 33.99±1.23°,less to the world-class players;the average release altitude is 2.03 ±0.03m;the average horizon distance to starting point of the release point is-0.03±0.08m.4.when they got the best achievement,the maximum velocity of center of mass of the top 3 athletes were respectively 2.84m/s,2.65m/s and 2.91m/s,and there is low-level correlation between the maximum velocity of center of mass and the achievement,and their release velocity were respectively 12.69m/s,13.31m/s and 13.84m/s,and their release angle were respectively 38.5o,35.5° and 33.9°;and their release altitude were respectively 2.09m,1.98m and 2.06m.
