运动生物力学理论认为:背越式跳高采用弧线助跑能使运动员的身体自然倾向圆心,这不仅有助于运动员在最后几步降低重心,而且也为运动员提供腾空绕横杆旋转的动力。由于身体内倾助跑并在起跳阶段转为垂直,这样就会使运动员在起跳结束时产生离心力,而不需要任何附加用力便能使运动员转动过杆,因而这种助跑将更有助于运动员创造优异成绩。以此我们认为弧线助跑在跳高中比直线助跑更为 Biomechanics theory that: back to the type of high jump using arc-runner can make athletes body natural tendency to center, which not only helps athletes in the last few steps to reduce the center of gravity, but also for the athletes to vacate the power around the bar rotation. Because the body is tilted and turned vertical during take-off, this will give the athlete a centrifugal force at the end of take-off without any additional force that will allow the athlete to roll over the pole, and thus such a run will be more helpful to the athlete in creating excellence Score. In this regard, we believe that the arc run in the high jump than the straight run more
