| 摘 要： | 依据资料所提供的中外优秀跳远运动员的运动学数据，运用动力学的方法分析比较了中外优秀跳远运动员之同的水平冲力和垂直冲力之间的差距。发现国内运动员水平冲力和垂直冲力普遍低于国外运动员；而且水平冲力和垂直冲力之间的关系不密切，国内运动员对水平冲击所产生的弹性能利用效率较低；并总结出了跳远助跑的两种模式及其动力学过程。

| Abstract: | According to the dynamic data of topnotch long jump athletes in the world,the difference of horizontal and vertical momentum between chinese and foreign topnotch long jump athletes was compared and analyzed in dynamics method.It is found that the horizontal and vertical momentum of chinese topnotch long jump athletes is all less than foreign athlete's one,the connections between horizontal and vertical momentum among chinese athletes is also not as close as among foreign athletes,and the efficiency of utilizing elastic energy produced when horizontal momentum happened is low.Besides,two models of approach about long jump and it's dynamics procedure are concluded. |
