[Purpose] The purpose of this study is to draw practical implications applicable to the field through analysing serial multiple mediator model of self-leadership, psychology empowerment, job satisfaction and organizational citizenship behavior. [Methods] In order to achieve the purpose of this study, we surveyed Korea national league players(187 usable sample). Four hypotheses were tested using frequency analysis, exploratory factor analysis, reliability analysis, correlation analysis and PROCESS macro through SPSS statistics. [Results] The results are as follows. First, self-leadership has a significant effect on organizational citizenship behavior. Second, mediating effects of psychological empowerment between self-leadership and organizational citizenship behavior were significant. Third, mediating effects of job satisfaction between self-leadership and organizational citizenship behavior were significant. Fourth, serial multiple mediator effects leading to self-leadership→psychological empowerment→job satisfaction→organizational citizenship behavior were significant. [Conclusions] Korea national league players must perform self-leader, goal setting, self-observation, self criticism, constructive thinking strategies, dedication and voluntary attitude for clubs and colleagues. The team’s coaches should strive to praise the athletes for their pride, provide appropriate feedback, prevent job burnout, and the management of front office should make practical efforts such as improving the welfare environment and presenting the future vision of club.
