| Abstract |
| Mental fatigue is a state of reduced mental and physical responsiveness from extended cognitive effort. Despite growing recognition its impact athletic performance, it has received limited attention sports injury research. Mental fatigue can impair concentration, reaction time, motor accuracy, thereby increasing risk sports-related injuries. It may also disrupt decision-making, neuromuscular coordination, potentially predisposing athletes more severe soft-tissue damage. However, little is known about how mental fatigue relates severity injuries across different body regions. This study aimed examine association between mental fatigue and severity soft-tissue injuries in upper limbs, lower limbs, trunk among amateur male bodybuilders. Methods: This cross-sectional study recruited 80 amateur male bodybuilders aged 18–30 years who had consistently trained at least three times per week during past three months. Mental fatigue was assessed using (MFS), validated self-report questionnaire. Severity soft-tissue injuries in three regions (upper limbs, lower limbs, trunk/back) was determined based total number training days lost due injury during past three months, documented gym medical records certified staff. Age, injury history within previous 12 months, weekly training load (session-RPE × session duration) were included covariates. Data were analyzed using Pearson correlation, multiple linear regression. Statistical significance was set p < 0.05. Ethical approval was obtained, informed consent was provided all participants. Results: Mean MFS score was 42.3 ± 10.5. Mental fatigue was significantly positively correlated with injury severity in upper limbs (r = 0.31, p = 0.005), lower limbs (r = 0.38, p < 0.001), trunk/back (r = 0.29, p = 0.009). Regression analyses confirmed mental fatigue as significant predictor injury severity across all body regions (β = 0.28–0.36, R² = 0.18–0.24, all p < 0.01). Conclusion: Mental fatigue is associated with greater severity soft-tissue injuries among amateur male bodybuilders. Regular screening, psychological interventions may help reduce injury risk. Longitudinal, interventional studies are recommended clarify causality. |
