摘　　要：为探讨上肢鞭打动作运动生物力学原理,我们采用数学模拟的方法对优秀男子标枪运动员投掷过程中上肢动作进行了分析。结果表明,合肌力矩的分布特点与下肢鞭打动作的分布特点有较大的区别;关节反力对环节的转动有较大影响;在上肢鞭打动作中,近侧环节运动对侧环节运动的影响,不完全能用"角动量传递"的理论来解释。Upper limb throwing movements of male javelin athletes were analyzed with mathematical simulation to study the biomechanical principles of upper limb whiplash movements.It was showed that the changes of the resultant muscular moments of upper limb were quite different from that of the lower limb in whiplash movements;there was a great effect of the joint reaction force on the segment rotation;and the influence of the proximal segment motion on the distal segment motion coule not be completely explained by the theory of 'transfer of angular momentum' in upper limb whiplash movements.
