我国优秀女子速滑运动员下肢肌群力学特性的分析

为了找出使用新冰刀后蹬冰时下肢三关节肌群的生物力学特性,首次利用数值计算中的牛顿插值法,将等动测试获得的动力学数据和三维立体解析获得的运动学数据结合,绘出两名优秀女子速滑运动员实际蹬冰时肌群力矩的变化曲线,并分析肌力变化特点,找出两人做功明显不足的原因,为指导训练和提高运动成绩提供定量依据。

Research on the Mechanics Feature of the Lower Limbs Muscles of Chinese Elite Female Speed-skaters

In order to find out the biomechanics feature of three joints muscles of lower limbs by using new skates in push-off phase of speed skating, this article combines the kinetic data obtained by Cybex-Norm and kinematic data obtained by tridimensional analytics by employing the Newton interpolation polynomial for the first time, draws the curve of muscles moment of two elite female speed-skaters in push-off phase of speed skating, and analyzes the change feature of muscle strength, so as to find out the reasons of less power output and provide reference for training and the improvement of sports results.
