This study was aimed to investigate impacts of metacognition on sport psychological skills and perceived performance in Korean adolescent football players. In total, 243 adolescent football players were participated in this study. Sport psychological skills (self-confidence, concentration, optimistic attitude, no focusing on result, and enjoyment), perceived performance, metacognition, and self-management were collected using questionnaires. A series of hierarchical multiple regression analyses were performed. Results showed that metacognition positively predicted self-confidence, concentration, optimistic attitude, enjoyment, and perceived performance. However, metacognition did not predict no focusing on result. These findings of this study suggest that coaches may employ meta-cognitive coaching to support psychological strength in regard to sport performances. Further research could usefully explore how specific meta-cognitive strategies affect psychological factors in football players.
