The purpose of this study was to identify the determinants of shooting performance in elite 10 m air rifle shooters. Twelve international-level 10 m air rifle shooters belonging to China's national team completed 60 shots using their normal shooting procedures. A SCATT MX-02 optoelectronic shooting test system was used to collect shooting score and shooting technical variables, while a footscan1.0 force platform was used to collect postural balance parameters. The principal component analysis identified five principal factors from 14 postural balance and shooting technical variables in elite 10 m air rifle shooters: holding and aiming, stability of triggering, time, A-P balance and M-L balance. Principal component regression analysis indicated that these five components explained the 83.1% variance of shooting performance. From these, the holding and aiming ability was the most important component, which could explain the 36.3% variance of shooting performance. The stability of triggering was the second important component, which could explain the 24.5% variance of shooting performance. The results of this study can be used to assess the strengths and weaknesses of performance-determining factors and to obtain more comprehensive information about the shooting action process during training.
本研究旨在确定优秀10米气步枪射击运动员射击成绩的决定因素。12名来自中国国家队的国际级10米气步枪射击运动员按照其正常射击程序完成了60次射击。使用SCATT MX - 02光电射击测试系统收集射击成绩和射击技术变量，同时使用footscan1.0测力平台收集姿势平衡参数。主成分分析从优秀10米气步枪射击运动员的14个姿势平衡和射击技术变量中确定了五个主要因素：握持与瞄准、扳机触发稳定性、时间、前后平衡和左右平衡。主成分回归分析表明，这五个成分解释了射击成绩83.1%的方差。其中，握持与瞄准能力是最重要的成分，可解释射击成绩36.3%的方差。扳机触发稳定性是第二重要的成分，可解释射击成绩24.5%的方差。本研究结果可用于评估成绩决定因素的优势与不足，并在训练期间获取有关射击动作过程的更全面信息。
