应用经典力学方法，建立人体处拉伸状态的力学模型。定义下肢与竖直面夹角θ为广义坐标。假设人体上身存在的弹性系数为k。下肢作微小摆动，利用拉格朗日方程解出K的数学表达式。通过数学式子可以说明k与下肢质量、下肢角速度、角加速度存在正比关系。

By using the method of classical mechanic principle, this paper sets up human upper mechanics model of draw state, define the angle between crura and vertical side as generalized coordinate. Suppose human elastic coefficient that upper body store is k. Let lower limb swing small angle, utilize Lagrangian equation solve and publish mathematics expression formula of K. Lower limb quality, angular velocity , angular accelerate have direct radio relations to k through mathematics equation.
