The aim of this study was to investigate the effects of mental fatigue on physical activity, technical and decision-making performance during small-sided games. Nine sub-elite soccer players were enrolled in the study. The players performed two small-sided games on two occasions within a crossover experimental design. Before each game, they underwent a mental fatiguing task (Stroop task) and a control task (documentary watching) in a randomized, counterbalanced order. Players' physical activity, technical, and decision-making performance were obtained during small-sided games by GPS and video scouting. Results showed that distance in acceleration covered per min, negative passes, passing accuracy, and shot accuracy were likely impaired than control task after a mental fatiguing protocol. Decision-making performance of negative passes, passes accuracy, and dribbling accuracy resulted also likely decreased compared with control task. These findings demonstrated that mental fatigue impacted on technical, GPS-derived, and soccer-specific decision-making performance during SSG. In conclusion, avoiding cognitively demanding tasks before playing soccer-specific activities may be advisable to preserve players' physical activity, technical, and decision-making skills.
本研究旨在探讨心理疲劳对小场比赛中身体活动、技术和决策表现的影响。9 名次精英足球运动员参与了这项研究。运动员在交叉实验设计中两次进行小场比赛。在每场比赛之前，他们以随机、平衡的顺序进行心理疲劳任务（斯特鲁普任务）和控制任务（观看纪录片）。通过 GPS 和视频侦察获得小场比赛中的运动员身体活动、技术和决策表现。结果表明，在进行心理疲劳方案后，加速度覆盖的每分钟距离、负传球、传球准确率和射门准确率可能会比控制任务受损。负传球、传球准确率和运球准确率的决策表现也可能比控制任务下降。这些发现表明，心理疲劳会影响 SSG 中的技术、GPS 衍生和足球专项决策表现。总之，在进行足球专项活动之前，避免认知要求高的任务可能有助于保持运动员的身体活动、技术和决策技能。
