Hand grenade throw is one of the five events in the international military games. Combining the movement of turning single arm cartwheel with the original position throw technic,a new technic of throwing grenade by turning single arm cartwheel is put forward in this paper,Using biomechanics to analyze the technic,its advantages are mainly shown in the folliwing; (1)The locus of run-up (cartwheel) is alike to the locus of final exertion,so it could apply the previous run-up velocity to the movement of final exertion effectively. (2) This technic has a more rational " surmountapparatus"——circular motion ,so it acts on the final exertion and makes a larger acceleration. (3)Thetechnic could get a maximum distance in doing mechanical work. In advance,it makes the muscles which take part in the final exertion get fully pulled,and makes a good basis for raising sports level.

投掷手榴弹是国际军事五项比赛项目之一。本文将单臂侧手翻动作与原地投手榴弹技术有机结合起来,提出一种新型的投弹技术——单臂侧手翻投掷手榴弹技术。从生物力学角度对该技术进行分析,其优点主要表现在三个方面:(1)助跑(侧手翻)动作轨迹与最后用力轨迹相吻合,能够将预先获得的助跑速度有效地运用到最后用力动作上去。(2)单臂侧手翻投弹技术有一个更加合理的“超越器械”动作——圆周式运动,进一步给最后用力以加速作用。(3)单臂侧手翻投弹技术在投掷时能获得最大的做功距离,使参与最后用力的肌群得到预先充分拉长,为提高运动成绩打下良好的基础。

the thesis analysed the reason why dangerous congditions ofen, bring about in excises of throwing hand grenades,according many years practice of education. This thesis argue that not only two courses must be prepared for but also scientific knowledge and careful steps must be used in the course of throwing in order to prevent accident.

结合多年的手榴弹实弹教学实践,分析了实弹教学险情发生的原因,总结了实弹教学顺利实施的影响因素。针对实弹教学的特点,提出了预防险情发生的措施和对策,认为实弹教学不仅要抓好准备阶段两个关键环节,还要采用科学的、周密的教学计划和步骤。

Fracture of shoulder bone in throwing hand grenade was studied with biomechanical methods.Three experiments were made and the result shows that the incorrect throwing movement,especiallythe motion of elbow,is the main reason of fracture.

本文应用运动生物力学影像测试图数分析方法研究投掷手榴弹中肱骨骨折问题。实验测试共进行3次(两次实弹投掷,一次实验室模拟测试),测试数据表明:投掷姿势不正确是造成肱骨螺旋性骨折原因之一,特别应注意投弹臂的肘部一定要在引臂时从肩后往上翻。经常纠正士兵的错误姿势能避免或减少骨折现象出现。
