投掷运动

the authors performed 3d photographic measurement on the technical moves of zhang wen-xiu as an excellent female hammer thrower in china to get relatively comprehensive body movement data by using two jvc3000 high-speed cameras, screened and analyzed the data by using spss software, and revealed the following findings: in terms of such technical parameters as spinning time, spinning track and spinning speed, there were some problems with this player, which restricted the enhancement of her performance, such as the double leg supporting time was shorter than the single leg supporting time; the angle of inclination of the track of various swirls was somewhat too big; the accelerating process was too short; too much attention was paid to acceleration at the single leg supporting stage; the spinning at the double leg supporting stage was too fast; the sustainable accelerating power was not high.

So the article focuses on the transition skill and how to affect the whole technique.Research method: Studying subject is Chinese excellent male shot-putter. Research methods are mathematics statistics and videotape analytic. We put two JVC GR-DVL9800 mini camcorders on the back of circle and the left side, they are made in Japan. And to take the whole match, then analysis the data, we found our players exist the shortcoming in skill by means of comparing with abroad athletes to be directed against individual character.

研究方法：以我国优秀男子铅球运动员为研究对象，采用录像解析和数理统计的方法，分别在投掷圈后侧和左侧各放一架日产JVC GR-DVL9800微型数字视频摄像机，完整地拍摄比赛全过程，而后对录像资料运用"爱捷"运动录像分析反馈系统进行数字化处理，并通过与国外优秀运动员的技术资料进行对比分析，针对我国运动员个人的技术特点，找出我国运动员技术方面存在的缺陷，并提出相应的解决措施，促使技术达到最佳化。
