| 中文摘要: |
| 对我国部分优秀男子标枪运动员从交叉步到出手过程中的动作技术进行了转动力学分析，计算出了人体表现出的各种能量、转动惯量、动量矩等动力学参数，对一些参数与运动员的成绩进行了相关分析，提出了最大“满弓”瞬间的动力学判断标准，发现了人体总体转动的节奏特征。 |
| 英文摘要: |
| Rotational dynamic analysis of the cross-stride to release technique of some elite Chinese male javelin throwers was made to calculate the different dynamic parameters of human body such as energy, moment of inertia, moment of momentum, etc. The article makes relative analysis of the parameters and the throwers' results. It puts forward the dynamic judgment criteria for the moment of "full bow" and the rhythmic characteristics of body rotation. |
