摆动和静止引体向上技术的力学分析

The Mechanics Analysis of Swinging and Static Pull up

在引体向上技术中，有两种技术形式，一种为静止发力向上拉起，一种为摆动发力向上拉起。同一个人在同等条件下，由于采用不同技术形式，最后成绩相差十分明显。摆动拉起技术的效果之高，令人惊奇。本文在力学、生物力学和能量转换等方面对两种技术进行分析、比较、研究，试图从中找出原理所在。

There two forms of technique in the technique of pull up/chinning.One is the static initiation of strength,the other is the swinging initiation of strength pulling upward.For the same person,under the same condition,due to applying different form of technique,the effectivenessof swinging pull up is such high that make one surprise.In this paper,the author tends to analysis,compare,and study these two forms of technique,using explanation of mechanics,biomechanics,and the transformation of energy,through which aim to find the basic principle of pull up/chinning.
