Laboratory-induced subjective mental fatigue (MF) has been shown to decrease sport-related performance (23, 38), yet there is a lack of research identifying tasks in real-world sport environments that induce MF (37). Since the identification of real-world tasks that induce MF may inform activities undertaken in the daily training and competition environments, the purpose of the current study was to compare changes in MF following a task designed to replicate the observation of game film to changes in MF following completion of a laboratory-based task (e.g., Stroop test). On separate counterbalanced visits, participants ( = 6) completed either (1) 35 min of replicated game film observation or (2) 35 min of the Stroop test. Visual analogue scales were used to measure MF, and a repeated measures analysis of variance [2 (time) x 2 (task)] was used to compare changes in MF following each task. No significant difference in changes in MF were found between conditions, (1, 5) = 1.226, = 0.319, and no main effect differences were found in MF pre-to-post for either task, (1, 5) = 2.211, = 0.197. Further efforts to identify real-world mentally fatiguing tasks are warranted.
实验室诱导的主观精神疲劳（MF）已被证明会降低与运动相关的表现（23, 38），然而，缺乏在真实运动环境中识别诱发MF任务的研究（37）。由于识别出真实世界中诱发MF的任务可能会为日常训练和比赛环境中的活动提供信息，本研究的目的是比较在一项旨在模拟观看比赛影片的任务后MF的变化与完成一项基于实验室的任务（如斯特鲁普测试）后MF的变化。在单独的平衡访问中，参与者（n = 6）完成了以下两项任务之一：（1）35分钟的模拟比赛影片观察或（2）35分钟的斯特鲁普测试。使用视觉模拟量表测量MF，并使用重复测量方差分析[2（时间）×2（任务）]来比较每项任务后MF的变化。在不同条件下，MF变化没有显著差异，F（$1, 5$）= 1.226，p = 0.319，并且两项任务中MF前后的主效应差异均未发现，F（$1, 5$）= 2.211，p = 0.197。因此，有必要进一步努力识别真实世界中导致精神疲劳的任务。
