Surprise, surprise ... a study in Switzerland into childhood fitness and obesity has found that children who do more physical activity throughout the school day, plus a ten minute fitness workout were fitter and less likely to put on less weight than those children who didn't perform the same physical activities.

Other recent studies have suggested that children merely compensate for the amount of PE they do at school by doing less physical activity at home and visa versa, less PE at school means more physical activty at home.

Others have suggested that it isn't the fact that children are overweight prompts them not to exercise, rather it's the fact that they don't exercise that they are overweight.

Research on children's fitness and obesity publish on the BMJ (British Medical Journal) online highlighted that children who were given an extra 60 minutes of physical activity on top of their normal PE lessons increased their running speed and dropped their body fat percentage. However, the study also highlighted that their overall daily physical activity levels and quality of life didn't significantly increase.
