This study explores how SPEPs influence physical activity, focusing on time management’s mediating role and grit’s moderating effect. A survey of 1,151 students from six universities used scales measuring attitudes, time management, grit, and physical activity. Results showed males scored higher in physical activity, time management, and grit. SPEPs indirectly influence physical activity through time management, with grit moderating this pathway. Recommendations include enhancing policy support, time management training, fostering positive psychological traits, and gender-sensitive interventions.
