Abstract: [Purpose] This study aimed to identify the body composition characteristics that differentiate regular and non-regular players in amateur soccer teams, thereby providing objective metrics for player selection and enhancing team performance. [Participants and Methods] A total of 147 male amateur soccer players (mean age 17.2 ± 4.9 years) were included and categorized as regular (n=68) or non-regular (n=79) players. Parameters of body composition including muscle mass and phase angle were measured using an InBody S10 analyzer. Groups were compared using unpaired t-tests and analysis of covariance adjusted for age, height, and weight. [Results] The regular players demonstrated significantly higher lean body mass, muscle mass, and phase angle. The trunk muscle mass and phase angle emerged as the key distinguishing variables. Logistic regression analysis revealed a significant association between phase angle and player regularity. [Conclusion] Trunk muscle mass and phase angle are effective indicators of regular player status. Phase angle, in particular, showed utility in objective player evaluations. These findings support the integration of trunk muscle mass and phase angle into the selection criteria and conditioning protocols for amateur soccer teams.
