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 .
Acceptability, feasibility and effectiveness of a computer-tailored physical activity intervention in adolescents.
OBJECTIVE To evaluate acceptability , feasibility and effectiveness of computer-tailored physical activity education among adolescents . METHODS Two classes of 7th grade rs from 10 r and omly selected schools were assigned to the intervention ( computer-tailored intervention , n=139 ) or control ( no-intervention , n=142 ) condition . Question naires were completed 1 week before and 3 months after the intervention . The computer-tailored intervention was completed during classes . RESULTS Students had few problems with the diagnostic questions and with the use of a computer . About half of the students evaluated the advice as interesting and easy to underst and and about 40 % as personally relevant , easy to use and credible . Half of students evaluated the advice as too long and only 33 % reported to have used the advice . The computer-tailored intervention was effective for increasing school related physical activity levels with on average 25 min per week ( F=3.4 , P < or = .05 ) , but not for increasing total physical activity or leisure time physical activity . CONCLUSIONS A 1-h computer-tailored intervention offered during class-time has the potential to increase school related physical activity . PRACTICE IMPLICATION S Although favourable effects of large scale implementation may be expected , some adaptations that might increase effectiveness should be investigated in the future
