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 .
In addition , WHO estimates that physical inactivity causes 10 % to 16 % of cases each of breast cancer , colon , and rectal cancers as well as type 2 diabetes , and 22 % of coronary heart disease and the burden of these and other chronic diseases has rapidly increased in recent decades .
OBJECTIVES The purpose of this systematic review was to summarize the evidence of the effectiveness of school-based interventions in promoting physical activity and fitness in children and adolescents .
Reducing sedentary behaviour and increasing physical activity among 10-year-old children: overview and process evaluation of the 'Switch-Play' intervention.
Overweight and obesity has doubled among children in Australia . There is an urgent need to develop primary prevention strategies to prevent current and future unhealthy weight gain . The aims of this paper are to describe a r and omized controlled trial ( ' Switch-Play ' ) developed to prevent unhealthy weight gain among 10-year-old children and to report the findings of the process evaluation . Children from three government primary schools were r and omized by class to one of four conditions : a  behavioural modification group ( BM ; n = 69 ) ; a fundamental motor skills group ( FMS ; n = 73 ) ; a  combined BM and FMS group ( n = 90 ) ; or a control ( usual classroom lessons ) group ( n = 61 ) . Children in the BM group participated in 19 sessions that encouraged them to reduce screen-based behaviours , and identified physical activity alternatives . The FMS group participated in 19 lessons that focused on mastery of six skills : run , throw , dodge , strike , vertical jump and kick . The combined group participated in all the BM and FMS activities . The intervention specialist teacher reported that the children showed high enjoyment and engagement ( 88 % lessons attended ) in most aspects of the programme . At-home tasks were completed by 57 - 62 % of the children , and 92 % completed the in-class tasks . Two-thirds of the children in the BM group participated in the behavioural contracting to switch off the TV . Most of the children reported high enjoyment of the programmes , and only a small proportion ( 7 - 17 % ) reported difficulties in switching off their nominated TV shows . More than half the children reported reducing their TV viewing ; however , less than half reported increasing their physical activity . It was found that most aspects of the intervention arms of the programme were successfully delivered to the majority of children participating in ' Switch-Play ' ; that the programmes were delivered as intended ; and that the programmes were favourably evaluated by participating children and their parents
