The study investigated the acute effects of cognitive effort and auditory distraction on inhibitory control, subjective mental fatigue, MOT skills, and HRV in professional soccer players during a prolonged endurance session, followed by a 24-hour follow-up evaluation. The findings showed that cognitive effort impaired inhibitory control and increased mental fatigue, but did not significantly impact MOT skills and HRV in the players.
Background: Throughout official soccer matches, the presence of cheer by the crowd could be considered a critical auditive distraction that could further impair the cognitive interference control system, multiple object tracking (MOT) skill, heart rate variability (HRV), and increase mental fatigue. As the resource is not immediately replenished, the impairment of the cognitive interference control system may be delayed following a soccer game. Then, evaluating the recovery time course of the cognitive interference control system, MOT skill, HRV, and mental fatigue after prolonged tasks combining physical, endurance, and cognitive effort are essential.Purpose: We aimed to analyze the acute effect of cognitive effort and auditive distractor with 24-h follow-up throughout a prolonged endurance session on inhibitory control, subjective mental fatigue, MOT skill, and HRV in professional soccer players.Methods: Twenty professional male soccer players were recruited (23.56 +/- 3.8 years, 78.1 +/- 6.9 kg, 1.77 +/- 0.06 m, and 12.5 +/- 5.3% body fat). The sessions were performed in a randomized and counterbalanced crossover design, divided into four experimental conditions: endurance, endurance + MOT, endurance + MOT + AD, and endurance + AD. The soccer players completed the incongruent Stroop task utilizing an eye-tracker to assess cognitive effort. MOT task, subjective mental fatigue, and HRV were evaluated before the endurance training (60%Delta of maximal aerobic velocity during 40-min) and after 30-min and 24-h of recovery. These sessions were designed to investigate the acute effect of prolonged cognitive effort (repeated MOT throughout the endurance task) and AD (constant crowd noise and coach's voice each 15-40 s, totalizing = 80 voices) on inhibitory control, MOT skills, HRV, and subjective mental fatigue after a fixed endurance training session.Results: There was no condition x time interaction for accuracy of inhibitory control (p > 0.05, eta p(2) = 0.001). There was a significant condition x time interaction for inhibitory control response time (p < 0.05, eta p(2) = 0.16). A higher response time of inhibitory control was found for the endurance + MOT + AD and endurance + MOT experimental sessions (p < 0.05). There was a significant condition x time interaction for subjective mental fatigue (p < 0.05, eta p(2) = 0.46). A higher subjective mental fatigue was found for the endurance + MOT + AD and endurance + MOT experimental sessions (p < 0.05). There was no condition x time interaction for HRV (p > 0.05, eta p(2) = 0.02).Conclusion: We concluded that cognitive effort throughout a prolonged endurance session impaired inhibitory control and increased mental fatigue without promoting greater MOT skill and HRV changes in professional soccer players.
