Purpose: The purpose of this study is to investigate the relationship between self-management of college taekwondo demonstration team members and their exercise commitment and perceived athletic performance. This study is highly anticipated to provide fundamental data to enable psychological understanding of the exercise commitment found among college Taekwondo demonstration team members in a competition and improving performance through the positive role of self-management. Method: The population of college Taekwondo demonstration team members nationwide was selected as the subject of the study. 600 copies were collected using the convenience sampling method and 555 of the collected copies, excluding those with inconsistent or unfaithful responses, were used for the analysis. Frequency analysis was performed to examine the general characteristics of the research subject, and exploratory factor analysis and Cronbach α coefficient, or an internal consistency test, were used to verify the validity and reliability of the research tool. In addition, correlation analysis and multiple regression analysis were performed to investigate the relationship among the variables of self-management, exercise commitment, and perceived performance with a significance level set to .05. Results: As a result of verifying each of the factors of self-management, exercise commitment, and perceived performance of Taekwondo demonstration team members through the Pearson correlation coefficient showed that all variables have a statistically significant correlation. The lowest correlation was found in body management and perceived performance(r=.213), whereas the highest correlation was found in cognitive commitment and behavioral commitment(r=.730). Conclusion: First, interpersonal management, training management, and mental management among the self-management factors of college Taekwondo demonstration team members were found to have a statistically significant effect on exercise commitment, though body management showed no statistically significant effect. Second, training management and mental management among the self-management factors of college Taekwondo demonstration team members were found to have a statistically significant effect on perceived performance, whereas no statistically significant effect was found from body management and interpersonal management. Third, among the factors of exercise commitment of college Taekwondo Demonstration team members across the nation, cognitive commitment was observed to have a statistically significant effect on perceived performance, whereas behavioral commitment showed no statistically significant effect.
