对速滑蹬冰加速理论的质疑与思考

Doubt and Reflection on the Accelerating Theory of Pushing in Speed Skating

对蹬冰的加速理论研究进行分析的结果认为:从前提出的加速理论,在反映高水平运动员加速能力时是有条件的,并且,认为IngenSchenau所提出的加速理论,还有待于经过实验加以验证。因此,单纯从获得速度改变量大小的角度来推断蹬冰加速的机制,并不是重心沿前进方向加速的唯一条件。

From the viewpoint of historical evolution, the paper concludes and analyses the accelerating theory of pushing. It indicates that on certain conditions the previous accelerating theory can reflect elite athlete's accelerating ability. It also admits that the theory put forward by Ingen Schenau still needs to be proved through experiments. Therefore, the mechanism that the accelerating theory of pushing depends on speed change is not the sole condition of the weight's acceleration forward.
