To investigate the impact of mental fatigue on the shooting accuracy and movement timing in the instep kick of Asian high-level soccer players.
Eight male collegiate soccer players (age 22.00 ± 0.93 years) were tested before and after mental fatigue induction. Mental fatigue was induced via a 30 min Stroop task. The effectiveness of fatigue induction was assessed using heart rate variability (HRV), a visual analog scale (VAS), rating of perceived exertion (RPE), and the Athlete Burnout Questionnaire (ABQ). Shooting performance was evaluated before and after mental fatigue using the Loughborough Soccer Shooting Test (LSST) and by evaluating timing by means of high-speed imaging.
Following mental fatigue induction, HRV decreased. Subjects' motivation (VAS) to exercise significantly decreased ( < 0.001), while VAS mental fatigue level ( < 0.001) and mental effort level ( < 0.002) significantly increased. Significant differences were observed after completing the Stroop task for ABQ Emotional/Physical Exhaustion ( < 0.007), Reduced Sense of Accomplishment ( < 0.007), Sport Devaluation ( < 0.006), and overall burnout level ( < 0.002). LSST showed that the subjects' left foot test scores (-4.13, < 0.013), right foot test scores (-3, < 0.001), and total scores (-3.16, < 0.001) significantly decreased. Although movement times increased slightly after fatigue, they did not reach statistical significance.
Mental fatigue significantly impairs the shooting accuracy of collegiate soccer players, as evidenced by decreased LSST scores. However, it has no significant effect on event duration during shooting execution. Mental fatigue affected decision-making but not shooting movement timing. More cognitively challenging tasks are more affected by mental fatigue.
探讨精神疲劳对亚洲高水平足球运动员脚背射门准确性和动作时机的影响。
对8名男性大学足球运动员（年龄22.00±0.93岁）在精神疲劳诱导前后进行测试。通过30分钟的斯特鲁普任务诱导精神疲劳。使用心率变异性（HRV）、视觉模拟量表（VAS）、主观用力程度分级（RPE）和运动员倦怠问卷（ABQ）评估疲劳诱导的有效性。在精神疲劳前后，使用拉夫堡足球射门测试（LSST）评估射门表现，并通过高速成像评估动作时机。
精神疲劳诱导后，HRV降低。受试者的运动动机（VAS）显著下降（<0.001），而VAS精神疲劳水平（<0.001）和精神努力水平（<0.002）显著增加。完成斯特鲁普任务后，ABQ情绪/身体耗竭（<0.007）、成就感降低（<0.007）、运动贬值（<0.006）和总体倦怠水平（<0.002）存在显著差异。LSST显示，受试者的左脚测试成绩（-4.13，<0.013）、右脚测试成绩（-3，<0.001）和总成绩（-3.16，<0.001）显著下降。尽管疲劳后动作时间略有增加，但未达到统计学意义。
精神疲劳显著损害大学足球运动员的射门准确性，LSST分数下降证明了这一点。然而，它对射门执行过程中的事件持续时间没有显著影响。精神疲劳影响决策，但不影响射门动作时机。认知要求更高的任务受精神疲劳的影响更大。
