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 .
Exercise adherence and intervention effects of two school-based resistance training programs for adolescents.
OBJECTIVE The aim of this study was to evaluate the efficacy and feasibility of two school-based RT programs to improve muscular fitness and body composition in adolescents . METHODS The study was conducted in Australia from July 2008 to June 2009 . Participants [ n=108 , mean age (SD)=15.0 ( 0.7 ) years ] were r and omized to free weights ( n=37 ) or elastic tubing ( n=41 ) RT groups and a control group was recruited ( n=30 ) . Participants in the RT groups completed 2 sets of 10 - 12 repetitions on 10 exercises for 8 weeks . Waist circumference , body composition ( bioelectrical impedance analysis ) and muscular strength ( bench press and leg press ) were assessed at baseline and posttest . RESULTS Boys ( p<0.001 ) and girls ( p<0.01 ) in both RT groups improved their body composition over the study period . Boys in both RT groups significantly improved both upper and lower body strength and their improvements were significantly greater than changes observed in the control group . Girls in the free weights groups achieved larger improvements in lower body strength compared to the control group ( p<0.05 ) . CONCLUSIONS Free weights and elastic tubing RT are feasible and effective strategies for improving aspects of health-related fitness in adolescents
