| Abstract Introduction: This study investigated changes in physical performance and physical and mental fatigue in young soccer players throughout a competitive season to identify factors contributing to performance decline and suggest strategies for optimizing training, recovery, and injury prevention. Methods: This study monitored 19 young soccer players over 11 weeks to examine changes in physical performance and physical and mental fatigue. Fatigue was assessed using POMS and QFS, while performance was measured with CMJ, skill/movement tests, and the Yo-Yo test. Running distance and load were tracked via KMRM, with measurements taken at pre-, mid-, and post-season. Data were analyzed using repeated measures ANOVA. Results: The results revealed a significant decrease in explosive power (p = 0.003) and aerobic endurance (p = 0.001) over the course of the season, while both physical fatigue (p = 0.002) and mental fatigue (p = 0.004) increased significantly. Moreover, a significant negative correlation was observed between changes in mental fatigue and physical performance (r = 0.61, p < 0.01). Motion-tracking data also indicated a noticeable decline in high-speed running distance during the final weeks of the season (p = 0.005). Conclusion: The findings suggest that increases in physical and mental fatigue throughout the competitive season are associated with declines in physical performance, particularly in power and endurance capacities. Continuous monitoring of fatigue and training load using tools such as POMS, QFS, and KMRM10 can play a critical role in optimizing training programs, managing recovery, and preventing performance decrements among young soccer players. |
