运用运动解剖学和生物力学理论及文献资料方法,对标枪最后用力技术进行了生物力学分析,结论表明,标枪的最后用力就是充分利用助跑速度获得动量在尽可能长的工作距离内将最大的力作用于标枪,使标枪在出手时刻达到最高速度,并沿着合理角度出手;最后用力技术的关键在于把握好髋部运动的用力时机,在快速助跑中应不停顿地完成最后用力技术将标枪掷出的过程;最后用力的顺序是取得最大出手速度的关键,左腿单支撑和“鞭打”动作、出手动作对标枪成绩起着至关重要的作用。
Using the methods of sports anatomy, biomechanical theory and literature review, the biomechanical analysis of the final force of the javelin was carried out. The conclusion shows that the final force of the javelin is to make full use of the velocity of the run-up to obtain the momentum and to maximize the force in the longest possible working distance The role of the javelin, the javelin shot at the moment to achieve maximum speed, and shot at a reasonable point; the last force technology is the key to grasp the hard-hips of the moment, in the fast run should be completed without stopping the final force technology javelin throw Out of the process; the last force order is to obtain the maximum speed of the key, the left leg single support and “whipping ” action, shot action on the javelin plays a crucial role.
