摘要
运用运动生物力学的手段和方法对张英宁4.46m的成绩进行技术分析,这个成绩在2007年3月份全国室内田径锦标赛上打破了全国田径室内赛女子撑杆跳高的纪录,对张英宁最后两步进行运动学分析,得出张英宁最后一步的速度要比倒数第二步小,步长也比倒数第二步要小。最后的起跳动作干脆利索,为她后面的动作做了很好的准备。
By the method of kinematics, Kinematics analysis for Zhang yingning 4. 46m performance who break the national indoor track and field tournament of the women＇s pole vault record in the March 2007 National Indoor Track and Field Championships. carry out analysis of kinematics of Zhang Ning the last two steps, the final step velocity smaller than the second step. The final step was smaller than the last second. The finally of take--off action simply agile. She was back doing a very good preparation.
