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 .
Physical Activity Across the Curriculum (PAAC): a randomized controlled trial to promote physical activity and diminish overweight and obesity in elementary school children.
BACKGROUND Physical Activity Across the Curriculum ( PAAC ) was a three-year cluster r and omized controlled trial to promote physical activity and diminish increases in overweight and obesity in elementary school children . METHODS Twenty-four elementary schools were cluster r and omized to the Physical Activity Across the Curriculum intervention or served as control .  All children in grade s two and three were followed to grade s four and five .  Physical Activity Across the Curriculum promoted 90 min/wk of moderate to vigorous intensity physically active academic lessons delivered by classroom teachers . Body Mass Index was the primary outcome , daily Physical activity and academic achievement were secondary outcomes . RESULTS The three-year change in Body Mass Index for Physical Activity Across the Curriculum was 2.0+/-1.9 and control 1.9+/-1.9 , respectively ( NS ) . However , change in Body Mass Index from baseline to 3 years was significantly influenced by exposure to Physical Activity Across the Curriculum . Schools with > or = 75 min of Physical Activity Across the Curriculum/wk showed significantly less increase in Body Mass Index at 3 years compared to schools that had < 75 min of Physical Activity Across the Curriculum ( 1.8+/-1.8 vs. 2.4+/-2.0 , p=0.02 ) . Physical Activity Across the Curriculum schools had significantly greater changes in daily Physical activity and academic achievement scores . CONCLUSIONS The Physical Activity Across the Curriculum approach may promote daily Physical activity and academic achievement in elementary school children . Additionally , 75 min of Physical Activity Across the Curriculum activities may attenuate increases in Body Mass Index
