【摘要】：标枪属于体能主导类快速力量型项目,由身体末端发力作用于器械纵轴上非周期运动项目。躯干力量(即核心力量)不仅是投掷标枪主要发力源,而且也是上下肢力量传递的中间环节,因此躯干力量的强与弱对标枪专项成绩有一定影响作用。本文通过三维影像测试解析、实验等方法,以北京体育大学竞技学院24名二级水平男子标枪运动员作为实验对象,进行为期12周核心力量训练。经研究表明:实验组与对照组相比,在最后用力阶段,右脚着地时躯干后倾角、髋转角、右膝角有显著性差异;左脚着地时左膝角、投掷臂与躯干夹角、髋转角有显著性差异;枪出手瞬间出手速度、躯干后倾角、左膝角、标枪专项成绩有显著性差异。因此,核心力量训练对二级水平男子标枪运动员身体关节角度的改变、重心的稳定、发力时身体姿态的保持、满弓技术的形成发挥着特殊作用。
[Abstract]:Javelin is a kind of fast force item, which is applied by the end of the body to the aperiodic movement on the longitudinal axis of the instrument. The trunk strength (that is the core force) is not only the main source of javelin throwing but also the intermediate link of the upper and lower limb power transfer. Therefore the strength and weakness of the trunk force have certain influence on the javelin performance. In this paper, 24 second-level male javelin athletes in Beijing Sports University Athletics College were used as experimental objects for 12 weeks of core strength training. The results showed that there were significant differences between the experimental group and the control group in the posterior inclination angle, hip angle, right knee angle when the right foot landed on the ground, the left knee angle, the angle between the throwing arm and the trunk, and the hip rotation angle when the left foot landed on the ground, and the angle between the throwing arm and the trunk was significantly different between the experimental group and the control group. There are significant differences in the speedup, the inclination of the trunk, the left knee angle and the javelin score. Therefore, the core strength training plays a special role in changing the angle of body joint, stabilizing the center of gravity, maintaining the body posture and forming the full bow technique in the second level male javelin athletes.
