Athletic success is closely linked not only to physical abilities but also to mental skills like cognitive flexibility. Cognitive flexibility refers to an athlete's ability to adapt to rapidly changing game conditions, reorganize strategies, and make decisions under pressure. Complex game scenarios require athletes to continuously manage mental challenges. Regular sports activities improve stress management and emotional control, enhancing cognitive flexibility. Increased serotonin and dopamine levels from sports positively affect mental resilience and decision-making. Ultimately, cognitive flexibility plays a critical role in enhancing athletic performance and managing life challenges.
