足球中的扫描指的是主动的头部运动，球员的脸暂时从球上移开，以收集信息，为随后与球接触做准备。这项研究的目的是更多地了解英超俱乐部的27名优秀职业足球运动员在竞争性比赛中使用扫描的方式，这种行为在什么情况下表现出来，以及这些行为与表现之间的关系。球员们在21场比赛中被拍摄下来，总共产生了9574个球的个人持球量用于分析。扫描的特写视频分析显示了位置的差异(中场和中后卫扫描最频繁，前锋最少)和背景差异(在对手压力很大的情况下，在场上较宽的位置，更靠近对手球门的位置，以及在某些比赛状态下，扫描频率相对较低)。与运球、投篮或只接球时相比，球员在传球前更频繁地扫描，与短/后传相比，在更长/更向前的传球之前也更频繁地扫描，尽管这些差异很小。贝叶斯分层模型考虑了单个球员的差异和传球难度，该模型表明，球员扫描得越多，完成传球的可能性就越高。总而言之，比赛需求可能会限制精英球员扫描的程度，扫描似乎对精英足球运动员的表现起到了很小但积极的作用。
Scanning in football (soccer) denotes an active head movement where a player’s face is temporarily directed away from the ball to gather information in preparation for subsequently engaging with the ball. The aim of this study was to learn more about the ways that 27 elite professional football players in an English Premier League club use scanning in competitive matches, the conditions under which this behavior is exhibited, and the relationships between these behaviors and performance. Players were filmed across 21 matches, producing a total number of 9,574 individual ball possessions for analysis. Close-up video analyses of scanning show positional differences (with central midfielders and central defenders scanning most frequently, forwards least) and contextual differences (with relatively lower scanning frequency in situations with tight opponent pressure, in positions wide in the field and closer to the opponent’s goal, and under certain game state conditions). Players scan more frequently prior to giving passes than when they dribble, shoot, or only receive it, as well as prior to more long/forward passes compared to short/backward ones, although these differences are small. A Bayesian hierarchical model, which accounts for individual player differences and pass difficulty, suggests that the more a player scans, the higher the probability of completing a pass. In conclusion, match demands are likely to constrain the extent to which highly elite players scan, and scanning seems to have a small, but positive role in elite football players’ performance.
