我国高水平手枪慢射运动员瞄准技术的生物力学研究

本研究采用瑞典生产的高精度红外光点记录系统（ＳＥＬＳＰＯＴＳＹＳＴＥＭ），对我国四名优秀手枪慢射运动员瞄准阶段的身体环节和枪支的运动进行了测量，经研究发现：瞄准时间、击发前枪口的晃动量、击发瞬间枪口位置的差异三指标是瞄准阶段的重要技术指标，与射击精度有关，存在一定的规律性。通过测试分析，发现维持枪管左右方向（Ｙ方向）的平衡稳定难于其它两个方向，左右方向的晃动量对射击成绩有较大影响，同时，瞄准时间、击发前枪口的晃动量、击发瞬间枪口位置的差异几个技术指标之间存在着一定的相互制约关系。同时，还发现我国优秀射手在动作的一致性方面都还存在着一定差距；在瞄准时间、枪口晃动量、击发瞬间枪口位置三者的配合上不是很完善。

Biomechanical Study on Aim Technique in Elite Pistol Athletes of China

The high-techn Selspot System was used to measure the movement of the body-links and firearms in the aiming period in 4 elite male pistol shooters of China. It was gut that the firearms'kinematics and biomechanics data for diagnosing pistol aiming technique. The research found that it is important technical data that the aiming time, muzzle's wobbing degree before firing and the difference of muzzle's position in the twinking of firing. The data was related to the shooting precision. In the meantime, the research readings reveiled that, even for the elite athletes, there were some imperfect sides,such as the consistant of action and the cooperation among the aiming time, the muzzle's wobbling degree before firing and the muzzle's position in the twinkling of firing.
