Exploiting the long jump technique parameter and treading strength in the planting step - time curve , and analyzing the kinematics and dynamics reasons for the loss of approach velocity , taking - off rapid supporting and stretching in the generating mechanism of vertical velocity during long jump take - off , the essay puts forward a new view of generating vertical velocity and offers a new thought for creating training of long jump
摘要利用世界优秀运动员的跳远技术参数和跳远踏跳阶段踏跳力时间曲线，剖析助跑速度损失量、起跳快速支撑和蹬伸在跳远起跳垂直速度的生成机制中的运动学和动力学原因，对跳远垂直速度生成提出了新的见解，并为创新跳远训练提供了一条新的思路。
