PURPOSE: Professional football players experience both physical and mental fatigue. The main aims of this randomized crossover study were to investigate the effect of mental fatigue on repeated sprint ability (RSA), and the effects of both physical and mental fatigue on psychomotor vigilance.METHODS: Seventeen male professional football players performed maximal 20-m shuttle sprints interspaced by incomplete recovery (RSA test). Running speed, heart rate (HR), brain oxygenation and rating of perceived exertion (RPE) were monitored during each sprint. The RSA test was preceded by either a 30-min Stroop task to induce mental fatigue (MF), or by watching a documentary for 30 min (CON) in a randomized counterbalanced order. Participants performed a psychomotor vigilance test (PVT) at baseline, after the cognitive task (MF or CON), and after the RSA test.RESULTS: HR and RPE significantly increased, while running speed and brain oxygenation significantly decreased over the repeated sprints (p < 0.001) with no significant differences between conditions. Response speed during the PVT significantly declined after the Stroop task but not after CON (p = 0.001). Response speed during the PVT declined after the RSA test in both conditions (p < 0.001) and remained lower in the MF condition compared to CON (p = 0.012).CONCLUSIONS: Mental fatigue does not reduce RSA. However, the results of this study suggest that physical and mental fatigue have negative and cumulative effects on psychomotor vigilance. Therefore, strategies to reduce both physical and mental fatigue should be implemented in professional football players.
