The purpose of this study was to investigate the temporal phases of the archery shot cycle that distinguish the arrows distance from centre, in an attempt to understand critical factors that affect performance. Fifteen archers of varying ability each performed 30 shots at 18 m. Fourteen potential predictor variables were measured for statistical modelling by stepwise multiple linear regression. The results show that pre-shot time (pre-performance routine), follow-through time (post-performance routine), aiming time, speed of the arrow and the %variation in clicker-release time, account for 7.7% of the variation in predicting shot performance. The results have implications for practice demonstrating factors that coaches should focus on to develop their athletes. Further work on pre-, but more importantly, post-performance routines are needed generally within sport research as they are lacking and have been shown to be important contributing factors in a number of sports.
本研究的目的是调查射箭射击周期的各个阶段，这些阶段可区分箭与靶心的距离，以试图了解影响成绩的关键因素。15名能力各异的弓箭手在18米处各进行30次射击。通过逐步多元线性回归测量了14个潜在预测变量用于统计建模。结果表明，射击前时间（赛前准备程序）、随挥时间（赛后程序）、瞄准时间、箭的速度以及咔哒释放时间的变化百分比，占预测射击成绩变化的7.7%。研究结果对实践具有启示意义，揭示了教练在培养运动员时应关注的因素。在体育研究中，通常需要进一步研究赛前，更重要的是赛后程序，因为目前这方面的研究较少，且已被证明是许多运动项目中重要的影响因素。
