为研究不同的下肢前摆性鞭打动作对其所产生的髋、膝关节力矩的影响，本文运用三维录像解析系统，对5名体育专业大学生的三种不同下肢前摆性鞭打动作进行解析。对解析后的数据使用自编写的Matlab语言程序包进行分析，结果显示：在下肢前摆性鞭打动作开始时，髋关节屈力矩峰值由小到大分别为无预摆鞭打，被动预摆鞭打，主动预摆鞭打，且无预摆鞭打与被动预摆存在显著性差异，无预摆鞭打与主动预摆鞭打存在非常显著性差异；而在小腿加速前摆过程中，只有无预摆鞭打与主动预摆鞭打之间的伸膝关节力矩峰值存在非常显著性的差异。

In order to study the effect on joint-torque of hip and knee of different lower limbs swing forward whiplash,three different lower limbs swing forward whiplash of five college students majoring in physical edu-cation were analyzed by using 3D video and analytic system. The parsed data was analyzed by using self-written Matlab language program package. The results show that the flex torque peak of hip joint in ascending order is whiplash without preliminary swing,whiplash with passive preliminary swing,whiplash with active preliminary swing at the beginning of lower limbs swing forward whiplash. There is significant difference between whiplash without preliminary swing and whiplash with passive preliminary swing,and there is very significant difference between whiplash without preliminary swing and whiplash with active preliminary swing. In the process of calves’ accelerating swing forward,the peak torque of knee joint exists very significant difference only between whiplash without preliminary swing and whiplash with active preliminary swing.
