Visual gaze behaviour, and in particular Quiet Eye (QE), have been found to be important in aiming tasks in multiple sports. The aim of this study is to provide insight into the characteristics of gaze behaviour in a moving condition, that is of football players during the run-up and kick of free kicks. Fourteen skilled youth players performed a set of free-kick trials while their eyes were being tracked. Two QE periods have been determined prior to a critical phase of the kick: QE Target and QE Ball. For the scored trials both the QE Target (M = 886 ms SE = 78 ms) and QE Ball (M = 627 ms SE = 52 ms) duration were significantly longer than in the missed trials, QE Target (M = 488 ms SE = 45 ms) and QE Ball (M = 513 ms SE = 80 ms). The analysis of the number of fixations suggests that one fixation on a target is the optimum, and more (2-3x) or no fixations resulted in less accurate shooting. These results provide insight into the characteristics of football shooting that can be incorporated into shooting practice in order to improve performance.

足球中任意球时的视觉凝视行为

已发现视觉凝视行为，尤其是静眼 (QE)，在多项运动中的瞄准任务中很重要。本研究的目的是深入了解运动状态下的凝视行为特征，即足球运动员在助跑和任意球踢球时的凝视行为特征。十四名技术娴熟的青年球员在他们的眼睛被跟踪的同时进行了一组任意球试验。在关键阶段之前已经确定了两个 QE 时期：QE Target 和 QE Ball。对于评分试验，QE Target (M = 886 ms SE = 78 ms) 和 QE Ball (M = 627 ms SE = 52 ms) 持续时间明显长于错过的试验，QE Target (M = 488 ms SE = 45 ms）和 QE Ball（M = 513 ms SE = 80 ms）。对注视次数的分析表明，对目标的一次注视是最佳的，并且更多（2-3x）或没有注视导致不太准确的射击。这些结果提供了对足球射门特征的洞察，可以将其纳入射门练习以提高表现。
