速滑弯道技术的生物力学分析

The Biomechanical Analysis of the SpeedSkating the Curve Technology

本文根据生物力学理论和弯道技术动作的特点，建立人体五杆模型，以蹬冰腿的膝关节角为控制变量，给出弯道上人体姿势控制方程，其中控制变量包括人体尺寸、倾斜角度等，方程的数值解同实际观察的现象相吻合。

In the paper,according to the theory of sports biomechanics and movement properties of the curve technology,the five segment model of human body is proposed.Assuming the rotating angle of knees joint as control variation,the equation of the parameters controlling human bodys posture is deduced,the parameters contain human bodys dimension,etc.The results of numerical value is accord with the phenomena observed in practice of speed skating the curve.
