Abstract:
The study investigated associations between selected physical activity correlates among 299 adolescents (90 boys, age 12-14 years) from 3 English schools. Physical activity was assessed by self-report and accelerometry. Correlates represented biological, predisposing, and demographic factors as described in the Youth Physical Activity Promotion Model. Boys engaged in more self-reported (p < .01) and accelerometer assessed physical activity than girls (p = .02). Positive associations between sex (male), BMI, Perceived PE Ability, Perceived PE Worth, number of enrolled students, and physical activity outcomes were evident (p < .05). School-based physical activity promotion should emphasize sex-specific enhancement of students' perceived PE competence and enjoyment.
