The study aimed to investigate physical selfconcept differences based on gender and extracurricular involvement. Two hundred and three students, 112 were male and 91 females, 76 non-involvement extracurricular, 31 sports extracurricular and 96 other extracurricular involvement were completed: Physical Self-Description Questionnaire (PSDQ). Independent sample t-test was calculated to determine gender differences on physical self-concept, and One-Way ANOVA was calculated to determine based on extracurricular involvement. Significant differences were found on physical self-concept based on gender (p < .000), and based on extracurricular involvement (p < .000). In addition, results showed that gender and extracurricular involvement influences toward physical selfconcepts. Students who are involved in extracurricular have better physical self-concept than those who do not. This finding implies that student involvement in extracurricular activities is very important.
