The drag-flick is more efficient than hits or pushes when a penalty corner situation is in effect in field hockey. Previous research has studied the biomechanical pattern of the drag-flick, trying to find the cues for an optimal performance. On the other hand, some other studies have examined the most effective visual pick-up of relevant information in shots and goalkeeper anticipation. The aim of this study was to analyse the individual differences in the drag-flick pattern in order to provide relevant information for goalkeepers. One female skilled drag-flicker participated in the study. A VICON optoelectronic system (Oxford Metrics, Oxford, UK) was used to capture the drag-flicks with six cameras. The results showed that the main significant differences between right and left shots (p<0.05) in the stick angles, stick minimum angular velocity and front foot-ball distance were when the front foot heel contacted the floor (T1) and at the minimum velocity of the stick, before the dragging action (T3). The findings showed that the most relevant information might be picked up at the ball-and-stick location before the dragging action.
当曲棍球处于罚角球的情况下，拖拽击球比击打或推球更有效。之前的研究已经研究了拖拽击球的生物力学模式，试图找到最佳表现的线索。另一方面，其他一些研究已经研究了射门和守门员预判中最有效的相关信息视觉采集。本研究的目的是分析拖拽击球模式的个体差异，以便为守门员提供相关信息。一名女性熟练的拖拽击球手参加了这项研究。使用 VICON 光电系统（牛津度量，英国牛津）用六台相机拍摄拖拽击球。结果表明，在 T1（前脚跟接触地面时）和 T3（在拖拽动作之前，棒的最小角速度时），左右击球的棒角、棒的最小角速度和前脚球距离的主要显著差异（p<0.05）。研究结果表明，最相关的信息可能是在拖拽动作之前的球棒位置采集到的。
