This study applied the Extended Theory of Planned Behavior (ETPB) to examine factors influencing leisure-time exercise intention among college students in general physical education. The model integrated autonomous and controlled motivation with the traditional Theory of Planned Behavior (TPB) constructs—attitude, subjective norm, and perceived behavioral control—to identify key determinants of exercise intention. A survey of 304 students from universities in Seoul and Jeonbuk Province was analyzed using SPSS 27.0 and AMOS 21.0 through confirmatory factor analysis and structural equation modeling (SEM). Results showed that autonomous motivation positively affected attitude, subjective norm, and perceived behavioral control, whereas controlled motivation had negative effects. Among TPB variables, attitude and perceived behavioral control significantly influenced leisure-time exercise intention, while subjective norm was not significant. These findings highlight the need for teaching strategies that foster autonomous motivation and positive attitudes in general physical education. Emphasizing autonomy-supportive learning environments and motivational approaches can strengthen TPB variables, promoting sustained participation in physical activity and laying the foundation for lifelong exercise habits.
