Laterality (i.e., handedness, footedness, and eyedness) could have an impact on highly repeated soccer movements and thus, could influence performance. The purpose of this study was to examine the laterality of high-level football players and its effects on 180° left and right U-turn movements. Handedness, footedness, and eyedness were determined in 72 elite football players (EFP, 18.2 ± 2.2 years) from the Stade Rennais Football Club (French League 1) and 9 amateur football players (AFP, 19.6 ± 2.1 years). Players performed a visual-motor task on a synthetic pitch consisting of 180° left and right rotations as fast as possible in response to a visual light on a computer screen. Movement times and reactive times for each left and right rotation were recorded with an accelerometer and video display. Laterality profiles showed a majority (χ = 9.42, df = 2, = 0.031) of crossed formulas (i.e., dominant leg or hand is controlateral to the dominant eye) for EFP (53 ± 7%) and a majority of non-crossed formulas for AFP (63 ± 9%). Reaction times were significantly faster ( = 0.028, effect size = 0.148, trivial) in EFP right-eyed (568.2 ± 55.5 ms) than in AFP (610.0 ± 43.9 ms). For the left rotation and for right-footed players, movement times were significantly different ( = 0.043, effect size = 0.413, small) between EFP (1.15 ± 0.07 s) and AFP (1.17 ± 0.07 s). A significant difference ( < 0.033) was observed between footedness and rotation movement times in the EFP. Our results showed that laterality profiles differed between EFP and AFP. Hence, in EFP, reaction times depended on the side of the visual stimulus. Moreover, leg laterality of EFP influenced 180° left or right rotation speed. Our results indicate the importance of determining laterality in soccer players and identifying deficits in performance when turning.
偏侧性（即利手、利足和利眼）可能会对高度重复的足球动作产生影响，进而可能影响表现。本研究的目的是调查高水平足球运动员的偏侧性及其对180°左右转身动作的影响。对来自雷恩足球俱乐部（法国甲级联赛）的72名精英足球运动员（EFP，18.2±2.2岁）和9名业余足球运动员（AFP，19.6±2.1岁）测定了利手、利足和利眼情况。球员们在人造草皮上执行一项视觉运动任务，即根据电脑屏幕上的视觉灯光尽可能快地进行180°左右旋转。使用加速度计和视频显示器记录每次左右旋转的移动时间和反应时间。偏侧性特征显示，EFP中多数（χ=9.42，自由度=2，P=0.031）为交叉模式（即优势腿或手与优势眼对侧）（53±7%），而AFP中多数为非交叉模式（63±9%）。EFP中利眼者的反应时间（568.2±55.5毫秒）明显快于AFP（610.0±43.9毫秒）（P=0.028，效应量=0.148，微小）。对于左旋以及右利足球员，EFP（1.15±0.07秒）和AFP（1.17±0.07秒）之间的移动时间存在显著差异（P=0.043，效应量=0.413，小）。在EFP中，观察到利足情况与旋转移动时间之间存在显著差异（P<0.033）。我们的结果表明，EFP和AFP的偏侧性特征不同。因此，在EFP中，反应时间取决于视觉刺激的方向。此外，EFP的腿部偏侧性影响180°左右旋转速度。我们的结果表明确定足球运动员偏侧性以及识别转身时表现缺陷的重要性。
