本文主要应用运动生物力学研究方法采用QTM(Qualisys Track Manager)红外高速测试系统对陕西省射箭重点运动员永富军射箭技术动作进行运动学数据采集、对持弓肘进行分析发现在整个过程中持弓肘在上下方向上的晃动程度最为强烈,前后方向晃动程度最弱。放箭阶段的晃动对成绩的好坏有着明显的影响作用。持弓手在不同成绩环数的晃动规律不尽相同,主要是由于开弓阶段以及放箭阶段的晃动程度加大而引起晃动规律发生变化。 In this paper, kinematic data acquisition of the Yongfu Army’s archery key athlete in Shaanxi Province is carried out using the QTM (Qualisys Track Manager) infrared high-speed test system. The analysis of the holding elbow shows that during the whole process, The shakiness in the up-down direction is the most intense, and the shakiness in the front-back direction is the weakest. Archery stage of the shaking of the grades have a significant impact on the role. Archer hand swing in different performance ring number is not the same, mainly due to the bow stage and the stage of rocking increased shaking caused by changes in the law of shaking.
