With over 80% of adolescents globally being physically inactive, this study offers a novel perspective by investigating psychological resilience as a predictor of physical activity (PA). In a cross-sectional study of 909 Chinese adolescents (aged 13.3±0.5), boys demonstrated significantly higher resilience, PA levels, and better family functioning than girls. Crucially, adolescents from well-functioning families reported superior resilience and PA. Statistical modelling confirmed a significant positive relationship between resilience and PA, which was strongly moderated by family function type. The predictive strength of resilience on PA was significantly weaker in lower-functioning family environments compared to higher-functioning ones. These findings reveal that resilience is a positive predictor of adolescent PA, with family functioning serving as a critical moderator and gender as a key differentiating factor, highlighting the need for tailored intervention strategies.
