The consistency of an archer's postural set at the moment of loose (arrow release) is commonly perceived to be an important determinant of success. The coach seeks, among other things, to provide the archer with information about postural consistency, details of which he acquires by eye or occasionally by video-recordings. The gains that might be achieved from more precise information are examined here. Nine skilled archers, classified into either skilled or elite groups according to their officially computed handicap, were continuously monitored and measured with a three-dimensional co-ordinate analyser (Charnwood Dynamics Coda-3 Scanner) while shooting two ends (series) of three arrows each. Considerable variability was observed in the precision with which the positions of head, elbow and bow at the moment of loose were replicated by archers of similar levels of skill. These results are interpreted to suggest that precise postural consistency may not be the primary feature distinguishing between the performance of archers at the higher skill levels.
人们普遍认为,射手在松弦(箭射出)瞬间姿势的一致性是成功的重要决定因素。教练除其他事项外,还试图向射手提供有关姿势一致性的信息,他通过肉眼观察或偶尔通过录像来获取这些细节。本文探讨了从更精确的信息中可能获得的收益。九名熟练射手,根据其官方计算的差点分为熟练组或精英组,在每人射出两端(系列)、每组三支箭的过程中,使用三维坐标分析仪(查恩伍德动力公司的科达 - 3扫描仪)进行持续监测和测量。技能水平相似的射手在松弦瞬间头部、肘部和弓的位置复制精度方面存在相当大的差异。这些结果表明,精确的姿势一致性可能不是区分较高技能水平射手表现的主要特征。
