PURPOSE This study aimed to verify the relationship between adolescent athletes’ julsil, competitive trait anxiety, and self-management. METHODS A total of 370 adolescent athletes who were registered with the Korean Sport & Olympic Committee participated in the survey; 24 insincere responses were excluded from the analysis, leaving a total of 346 participants. After verifying the construct validity of the measurement tool used in the survey, statistical and correlation analyses were performed. The research model was subsequently verified using structural equation modeling. RESULTS Adolescent athletes’ julsil had a significant positive effect on self-management but not on competitive trait anxiety. In addition, self-management was found to have a significant negative effect on competitive trait anxiety, and also completely mediated the relationship between julsil and competitive trait anxiety. CONCLUSIONS Adolescent athletes’ julsil does not increase competitive trait anxiety, but rather plays a role in reducing it by increasing self-management. These findings unveil mechanisms through which julsil can be used to enhance athlete performance.
