射箭运动员在放箭时姿势的一致性通常被认为是成功的重要决定因素。教练寻求向射箭运动员提供有关姿势一致性的信息，这些信息是他通过眼睛或偶尔通过录像获得的。这里考察了从更准确的信息中可能获得的收益。9名熟练的射箭运动员，根据他们的官方计算障碍分为熟练组和精英组，在发射三箭的两端(系列)时，使用三维坐标分析仪(Charnwood Dynamic Coda-3扫描仪)进行连续监测和测量。类似技术水平的射箭运动员在放松时头部、肘部和弓部的位置复制的精确度上有相当大的差异。这些结果被解读为，精确的姿势一致性可能不是高技能水平射箭运动员表现的主要区别特征。
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.
