Results Physical activity was associated with numerous health benefits .
The dose-response relations observed in observational studies indicate that the more physical activity , the greater the health benefit .
Results from experimental studies indicate that even modest amounts of physical activity can have health benefits in high-risk youngsters ( e.g. , obese ) .
Vigorous intensity activities may provide even greater benefit .
Aerobic-based activities had the greatest health benefit , other than for bone health , in which case high-impact weight bearing activities were required .
Some of the health benefits can be achieved through an average of 30 minutes per day . [

In the absence of weight loss, exercise training does not improve adipokines or oxidative stress in overweight children.
The aim of the present study was to examine the effect of exercise training on adipokines , inflammatory markers , and oxidative stress in overweight children . Nineteen overweight children were r and omly assigned to an aerobic exercise training or sedentary control group for 8 weeks . Measurements included peak oxygen uptake ( V o(2)max ) , body weight and composition , adipokines ( C-reactive protein , interleukin 6 , tumor necrosis factor alpha , adiponectin , leptin , and resistin ) , and oxidative stress ( 8-isoprostane ) . There were no differences between groups for change in body weight or composition over the 8 weeks . Exercise training improved V o(2)max ( exercise group , 1.64 + /- 0.13 to 1.85 + /- 0.17L/min vs control group , 1.83 + /- 0.12 to 1.60 + /- 0.13 L/min , P < .05 ) but did not change any of the measured adipokines or the marker of systemic oxidative stress , 8-isoprostane . These data suggest that in the absence of weight loss , exercise training alone does not improve the adipokine profile or levels of oxidative stress in overweight children
