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 .
School-based exercise program improves fitness, body composition and cardiovascular risk profile in overweight/obese children.
We determined the effect of a school-based exercise training ( ET ) without dietary intervention , on body composition , fitness and cardiovascular risk in overweight/obese children . Subjects were 51 overweight/obese 6.5- to 12.5-year-old children ( 23 boys , 28 girls ; BMI 25.6+/-4.3 kg/m 2 ) , of whom 48 completed the program . Participants were enrolled in a 15-week aerobic training ( three 60-minute sessions/week ) . Working heart rate was between 120 - 185 beats/minute . Participation rate was 87 % . BMI , waist circumference , body composition ( bioimpedance ) , aerobic capacity ( treadmill ) , blood pressure , lipids and insulin sensitivity ( HOMA ) were assessed . Waist circumference ( 85.9+/-12.4 vs. 80.9+/-10.2 cm ) , muscle mass ( 32.4+/-6.2 vs. 33.7+/-6.1 kg ) , maximal oxygen consumption ( 37.0+/-3.9 vs. 42.6+/-11.2 ml/kg per minute ) , systolic blood pressure ( 113.3+/-11.2 vs. 106.7+/-11.6 mmHg ) and LDL cholesterol ( 2.4+/-0.6 vs. 1.9+/-0.6 mM/l ) improved significantly . Number of children with abdominal obesity ( 29 vs. 20 ) , hypertension ( 10 vs. 5 ) and elevated triglyceride ( 18 vs. 14 ) also declined significantly over time . We concluded that as a result of high attendance and appropriate training program , cardiovascular fitness and abdominal obesity improved in overweight/obese children along with the improvement in metabolic risk factor profile
