Sport psychology has emerged as a critical discipline in understanding and enhancing athletic performance, mental resilience, and overall well-being in sports. This letter synthesizes current knowledge and proposes future directions for research and practice in the field. Recent advances have demonstrated the effectiveness of psychological interventions, including cognitive-behavioral techniques, mindfulness training, and mental skills development, in optimizing athletic performance across various sports and competitive levels. The growing recognition of mental health challenges among athletes has further highlighted the need for comprehensive psychological support systems within sports organizations.
