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。 Through the literature, high-speed photography, kinematics analysis and other methods, we study the throwing technique of our country’s outstanding male roller caper Qi Taikai at the present stage. The first round of rotation has the problem of long support time, The acceleration time of the instrument is increased, and the acceleration of the center of gravity is late; the proportion of the double support time shortened in the third circle is too large, too much emphasis is put on the acceleration of the instrument, the timing is unreasonable; the fourth lap accelerates the instrument too early, Ineffective.
