摘要
对我国部分优秀女子三级跳远运动员在试跳过程中各跳起跳时着地动作的特点进行专门研究 ,同时从力学角度对着地技术的作用进行分析。主要采用摄像、录象解析法和文献资料调研。结论 :着地角的大小直接影响重心移过支撑点即前支撑时间的长短 ,从而影响水平速度的损失率 ,也是影响每一跳水平。
Through using the method of video camera,film analytics and literature,this paper makes specific study on characteristics of landing of our some elite female jumpers.At same time,landing skill is analyzed from the point of kinematics.The result shows that there exist great relation between landing angle and lose of horizontal speed.It is also an important factor that influencing vertical speed of jump.
