The pathway of social support in enhancing adolescents’ physical fitness: The mediating roles of physical activity and self-efficacy

This study provides insight into how social support impacts adolescent physical fitness. We found that social support strongly predicts both PA and self-efficacy, and self-efficacy significantly boosts PA, ultimately leading to improved physical fitness. Both self-efficacy and PA serve as mediators in the relationship between social support and fitness. Therefore, interventions should prioritise reinforcing social support, promoting PA, and nurturing self-efficacy to optimise adolescent physical fitness outcomes.
