射箭运动技术诊断是该项目科学化训练的难点和要点,研究结果发现,通过超高速影像和三维红外线运动学分析的方法,以及高精度的时间、速度、位移等系列运动学指标的测量和射箭运动力学原理的综合运用,能够有效地监控射箭运动员的专项技术状态;高水平射箭运动员专项技术动作具有撒放时间短、声动反应快、箭速高、动作稳定性和一致性高的特点;另外,从功能原理与专项技术规律角度深入分析了反向动作与动作效率、动作稳定性等要素的因果关系,提出了优化撒放方式、减小反向动作幅度、增强动作控制能力是提高射箭技术水平的重要途径。 |
英文摘要: |
Technical diagnosis of archery is a difficult key point of scientific training. The result of the study shows that the method of ultra-fast imaging and 3D infrared kinematic analysis and the comprehensive use of the high-precision measurement of the kinematic indicators of time, speed and shift and the principle of archery kinematic principle, may effectively monitor the status of specific technique of elite archers. The specific technique of elite archers features short release time, quick sound-action response, high arrow speed and high stability and consistency of movement. The paper makes an in-depth analysis of the correlation between reverse action and the factors of movement efficiency and stability from the aspects of function principle and the law of specific technique. It concludes that optimizing the way of release, decreasing movement amplitude and strengthening movement control ability are important in improving the technical level of archery. |
