There was some evidence that school-based physical activity interventions had a positive impact on four of the nine outcome measures .
Specifically positive effects were observed for duration of physical activity , television viewing , VO2 max , and blood cholesterol .
Generally , school-based interventions had little effect on physical activity rates , systolic and diastolic blood pressure , BMI , and pulse rate .
At a minimum , a combination of printed educational material s and changes to the school curriculum that promote physical activity result ed in positive effects .
Few changes in outcomes were observed in this up date with the exception of blood cholesterol and physical activity rates .
For example blood cholesterol was no longer positively impacted upon by school-based physical activity interventions .
The evidence suggests the ongoing implementation of school-based physical activity interventions at this time , given the positive effects on behavior and one physical health status measure .
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 .
A controlled trial of a school-based environmental intervention to improve physical activity in Dutch children: JUMP-in, kids in motion.
Interventions to promote physical activity are important in preventing children from becoming overweight . Many projects have been developed but only a few showed ( moderate ) effects . JUMP-in is a systematic ally developed primary -school-based intervention that focuses on the use of theory , environmental changes , parental influences and cooperation with multi-level parties in intervention development . The effects of JUMP-in were evaluated with a quasi-experimental pre-test/post-test research design . In total , 510 children from Grade s 4 , 5 and 6 of four intervention schools and two control schools in Amsterdam were followed for an intervention period of one school year . Changes in physical activity as well as in the social cognitive determinants were assessed using self-reports . In addition , a process evaluation has been executed . The results show that JUMP-in was effective in influencing physical activity , especially among children from Grade 6 . Children in the control group decreased their level of physical activity considerably , while activity levels in intervention children from Grade 6 remained stable . The intervention effects could not be explained by changes in the measured social cognitive determinants . In contrast , process information illuminated differences in intervention effects between the participating schools . The results from the JUMP-in study show the importance of intervention design s that focus on a theory-based mix of relevant environmental and social cognitive factors
