Since physical activity is part of a healthy lifestyle, there is a lot of interest concerning the determinants of this behaviour in youth since it is tracked into adulthood. Environmental determinants belong to one subset of factors that influence physical activity. Baseline and one-year follow-up data on level of physical activity were collected in classroom questionnaires from 1264 7th grade students (56.2% of eligible students). Physical activity was assessed via an adaptation of the Weekly Activity Checklist. The effect of a ban on extracurricular activities on adolescent physical activity levels was determined. Multivariate logistic regression analyses were used to determine the effect of the ban when controlling for baseline physical activity, the number of extracurricular activities regularly offered at the school, and season at baseline. Students attending high implementation schools were significantly more likely to increase their levels of physical activity after the ban was lifted, than students in low implementation schools (odds ratio (OR) = 1.49 (95% CI = 1.16, 1.91) and 2.19 (95% CI = 1.80, 2.67 for boys and girls respectively). These results suggest that a teachers' ban on sports-related ECAs was associated with a decrease in the PA levels of students attending secondary schools. The impact was higher among girls than boys.
