Abstract

BACKGROUND: Physical education (PE) lessons and leisure-time represent two important opportunities for adolescents to accumulate moderate-to-vigorous physical activity (MVPA). PURPOSE: Framed by self-determination theory, this study investigated how much of the observed variation in adolescent boys' MVPA levels (during PE and leisure-time) was explained by individual- and class-level motivation. METHODS: Cross-sectional design. Adolescent boys (N = 61, M = 14.36 years, SD = .48 years) completed motivation questionnaires and wore an accelerometer during a PE lesson and across 7 consecutive days. RESULTS: Self-determined motivation toward PE predicted MVPA during PE lessons (R(2) = .31). Self-determined motivation toward leisure-time physical activity was positively associated with MVPA during leisure-time (R(2) = .08). CONCLUSIONS: Findings support the tenets of self-determination theory and suggest that motivation may be an important correlate of adolescent boys' MVPA in PE lessons and during leisure-time. Also, results indicated that teachers' behavior may be an important determinant of MVPA in PE lessons, while individual motivation may be more important in leisure-time.
