There was some evidence that school-based physical activity interventions had a positive impact on four of the nine outcome measures .

BACKGROUND The World Health Organization ( WHO ) estimates that 1.9 million deaths worldwide are attributable to physical inactivity and at least 2.6 million deaths are a result of being overweight or obese .

Evaluation of an extra-curricular school sport programme promoting lifestyle and lifetime activity for adolescents
Abstract The purpose of this study was to evaluate the impact of an extra-curricular school sport programme to promote physical activity among adolescents . One hundred and sixteen students ( mean age 14.2 years , s = 0.5 ) were assigned to an intervention ( n = 50 ) or comparison group ( n = 66 ) . The 8-week intervention involved structured exercise activities and information sessions . Four days of pedometer monitoring and time spent in non-organized physical activity and sedentary behaviours were measured at baseline and post-test . At baseline , participants were classified using steps per day as low-active ( girls < 11,000 , boys < 13,000 ) or active ( girls ≥ 11,000 , boys ≥ 13,000 ) and the effects of the intervention were assessed using these subgroups . Adolescents in the intervention group classified as low-active at baseline increased their step counts across the 8-week intervention ( baseline : 7716 steps/day , s = 1751 ; post-test : 10,301 steps/day , s = 4410 ; P < 0.05 ) and accumulated significantly more steps ( P < 0.05 ) than their peers in the comparison group ( baseline : 8414 steps/day , s = 2460 ; post-test : 8248 steps/day , s = 3674 ; P = 0.879 ) . The results of the present study provide further evidence that physical activity monitoring using pedometers is an effective strategy for increasing activity among low-active adolescents
