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 .
Augmented trochanteric bone mineral density after modified physical education classes: a randomized school-based exercise intervention study in prepubescent and early pubescent children.
BACKGROUND Of the few exercise intervention studies focusing on pediatric population s , none have confined the intervention to the scheduled physical education curriculum . OBJECTIVE To examine the effect of an 8-month school-based jumping program on the change in areal bone mineral density ( aBMD ) , in grams per square centimeter , of healthy third- and fourth- grade children . STUDY DESIGN Ten elementary schools were r and omized to exercise ( n = 63 ) and control groups ( n = 81 ) . Exercise groups did 10 tuck jumps 3 times weekly and incorporated jumping , hopping , and skipping into twice weekly physical education classes . Control groups did regular physical education classes . At baseline and after 8 months of intervention , we measured aBMD and lean and fat mass by dual-energy x-ray absorptiometry ( Hologic QDR-4500 ) . Calcium intake , physical activity , and maturity were estimated by question naire . RESULTS The exercise group showed significantly greater change in femoral trochanteric aBMD ( 4.4 % vs 3.2 % ; P < .05 ) . There were no group differences at other sites . Results were similar after controlling for covariates ( baseline aBMD change in height , change in lean , calcium , physical activity , sex , and ethnicity ) in hierarchical regression . CONCLUSIONS An easily implemented school-based jumping intervention augments aBMD at the trochanteric region in the prepubertal and early pubertal skeleton
