这项研究从生物力学角度量化了六名精英守门员在三种不同扑救高度下向自己喜欢和不喜欢的一侧扑救的运动模式。同步三维运动学和动力学生物力学数据分析发现跳水方向显着（P < 0.05）影响跳水扑救的运动模式。非首选侧在起始事件中显示出更大的骨盆和胸部侧向旋转。这些过度旋转差异在平板阶段期间有所减少，而胸部在起飞时没有表现出显着差异；尽管骨盆仍然存在差异。这些过度旋转随后与更大的峰值膝关节力矩、更低的峰值踝关节力矩、起飞时较少的髋部伸展以及质心 (COM) 移动得更慢且不太直接到球（通过起飞时的净投射角测量）相关。这些结果表明，在骨盆和胸部潜水开始事件时或之前横向平面中的关节运动是随后不对称的原因。这些观察到的差异表明，事先了解对方守门员的肢体偏好是有优势的。
This study biomechanically quantified the movement patterns for six elite goalkeepers making diving saves to their preferred and non-preferred side at three different dive heights. Synchronised three-dimensional kinematic and kinetic biomechanical data analysis found diving direction to significantly (P < 0.05) influence the movement patterns of the diving save. The non-preferred side displayed greater lateral rotation of the pelvis and thorax at the initiation event. These over-rotational differences were reduced during the time on plate phase with the thorax displaying no significant difference at take-off; although a difference still remained for the pelvis. These over rotations were subsequently linked to greater peak knee joint moments, lower peak ankle joint moments, less hip extension at take-off, and for the centre of mass (COM) to travel slower and less directly to the ball, as measured by the net projection angle at take-off. These results indicate that joint movements in the transverse plane at or before the initiation event for the dive for the pelvis and thorax are the causation for subsequent asymmetries. These observed differences indicate that there is an advantage in having prior knowledge of limb preference in an opposing goalkeeper.
