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 .
Effectiveness of a computer tailored physical activity intervention in adolescents compared to a generic advice.
OBJECTIVE To investigate the differences in effects of a computer tailored physical activity advice as compared to generic information in adolescents . METHODS Students ( mean age , 14.6+/-1.2 ) out of 90 classes from six different Flemish schools were r and omly assigned to the tailored intervention ( n=563 ) or the generic non-tailored intervention ( n=608 ) condition . Both interventions included information on public health recommendations and tips on becoming more active . Participants in both groups received their assessment and feedback at baseline , at 4 weeks and at 3 months during school hours . Physical activity levels were determined using an adolescent adaptation of the International Physical Activity Question naire ( IPAQ ) . RESULTS After 4 weeks , almost all physical activity scores increased over time in both the generic and the tailored intervention group . No differences between groups were found ( all F < or = 0.07 ) . After 3 months , the generic intervention was more effective for increasing ' walking in leisure time ' among students not complying with recommendations . For all other physical activity scores , no differences between groups were found ( all F < or = 2.3 ) . CONCLUSIONS In contrast to the expectations , changes in physical activity scores did not differ between the tailored and the non-tailored intervention group . For most of the physical activity scores increases were found in both groups
