背越式跳高抛物线轨迹的力学研究

Dynamic Study of the Parabolic Path of Fosubry Flop

运用运动生物力学的力学分析原理对背越式跳高弧线助跑、起跳、起跳结束瞬间身体的受力进行定性分析研究,得出各分力对过竿抛物线的影响,以及其各个力产生的过程及作用,从而为指导跳高运动的教学和训练工作提供了一定的理论依据.

A qualitative analysis of the force received by the high jumper at approach run,takeoff and at the moment takeoff ends is made using force analysis principles of biomechanics of sports.The effect of the forces on parabola on which the high jumper flies over the top of the bar and the process these forces generate and their role are obtained,which provide a theoretical basis for the coaching and training of high jump.
