通过文献资料法,专家访问法,近景动态立体摄像测量法,三维运动学分析法,数理统计法等方法,以我国8名优秀男子铅球运动员为研究对象,对推铅球滑步阶段技术进行了分析研究.结果显示：滑步阶段右脚离地瞬间,我国运动员的身体重心水平速度偏小,垂直方向的速度偏大;两大腿夹角偏小;右脚蹬地角偏大,平均值为74°±5°;滑步时间长;左、右腿摆蹬的力量、幅度以及配合都不适当.
통과문헌자료법,전가방문법,근경동태입체섭상측량법,삼유운동학분석법,수리통계법등방법,이아국8명우수남자연구운동원위연구대상,대추연구활보계단기술진행료분석연구.결과현시：활보계단우각리지순간,아국운동원적신체중심수평속도편소,수직방향적속도편대;량대퇴협각편소;우각등지각편대,평균치위74°±5°;활보시간장;좌、우퇴파등적역량、폭도이급배합도불괄당.
This text applies the law of documents and materials, the expert visits, close shot three- dimensionally video recording, the analytic approach of three- dimensional kinenratics, and the statistic law of mathematics and physics, etc., to research into elite men＇ s shot - put technique in China. The result indicates that ：（ 1 ） On the right foot twinkling of an eye, the horizontal velocity of centre of body weight of athletes is lower; The speed of the vertical direction is partial and large; The angle between two legs is partial and too small; The take off angle of right foot is partial and big; The average is 74 ＋ 5°; Sliding step time is long; The strength and wave range of left and right legs and their cooperation is inappropriate.
