摘　　要：通过文献资料、高速摄影、运动学解析等方法,对现阶段我国优秀男子链球运动员齐大凯的投掷技术进行研究发现:旋转第一圈存在单支撑时间偏长,器械加速时机早的问题;第二圈增加了对器械加速时间,重心加速时机晚;第三圈双支撑时间缩短比例偏大,过多强调对器械加速,时机不合理;第四圈对器械加速过早,持续加速能力差,整体用力效果不好。Methods like literature consultation, high-speed photography, kinematics analysis were used to analyze Male Hammer Throwers Qi Dakai at stage of the throwing technique. Results show that there are single support long hours and untimely accelerating rotation process equipment at the first lap. During the second circle, there is increased time of accelera- tion of the equipment. Meanwhile, the center of gravity to be accelerated is lag behind. The timing of late third lap time double support ratio is ill-proportionate and there are too much emphasis on equipment acceleration. Accelerating time is unreasonable in fourth lap equipment. There is sustained acceleration capacity needed to be improved. The overall force application is thus less effective.
