This study examined the relationships between social physique anxiety (SPA) and physical activity and sedentary behaviours among older adolescents. The research was grounded in self-determination theory (SDT; Deci & Ryan, 1985). Three hundred and eighty one males and females completed scientifically-supported questionnaires. Multivariate and univariate analyses of variance revealed that male adolescents reported lower SPA and higher competence, relatedness, self-determined motivation, and physical activity levels compared to females. Regression analyses supported the integration of SPA in SDT, and the main tenets of SDT were maintained. Specifically, the basic psychological needs were important correlates of motivation, and motivation was a positive correlate of PA behaviour and a negative, albeit weak, correlate of sedentary behaviour. Collectively, these findings suggest that SPA experiences can be understood within a motivational framework that explains the functional role played by SPA on health behaviour.
