Abstract
Introduction: Mental fatigue significantly impacts sports performance, particularly in precision-oriented disciplines such as air pistol shooting. This research aims to investigate the effects of mental fatigue on performance accuracy and alpha wave activity with EEG in air pistol athletes.
Method: This semi-experimental study involved two groups, consisting of 20 shooters divided into a mental fatigue group (N = 10 participants) and a control group (N = 10 participants). The Stroop test was employed to induce mental fatigue. Sports performance was assessed by having participants shoot 15 arrows at a shooting range, while alpha wave activity was measured using a 30-channel electroencephalography (EEG) device in two phases: before and after the shooting test. Statistical analysis was conducted using MATLAB, EEGLab, Excel software and 2x2 mixed analysis of variance with SPSS version 26 software at a significance level of 0.05.
Results: The results indicated that the mental fatigue group exhibited a decrease in shooting accuracy performance and an increase in alpha wave activity across five brain regions (F4, Ft7, C4, T8, P7), specifically in the frontal, central, temporal, and parietal areas. However, no changes were observed in the control group.
Conclusion: These results highlight the significance of managing mental fatigue in precision-oriented sports and suggest the development of training programs and coping strategies aimed at reducing mental fatigue to enhance athletes' performance.
