This study explored how university-student coaching impacts junior high students’ athletic development. Coaching behaviors affect children’s attitudes towards and engagement in sports. External weekend coaches were assigned to support this initiative. The purpose of this study was to determine which types of coach-student interactions most effectively promote development. The participants included 195 junior high school students residing in City K (121 males and 74 females; mean age = 13.48 ± 0.58 years). Survey measures focused on sport-related development, experiences of interaction with university student coaches—including acceptance, close engagement, and affirmation from mentors—and club activity adjustment, such as motivation toward participation. Results indicated that higher levels of club activity adjustment correlated with greater perceived personal growth. These findings underscore the importance of accepting and supportive behaviors for university student coaches working with adolescents.
