The study, reported in JAMA, randomly assigned over 200 overweight or obese grade school students to 20 or 40 minutes of supervised aerobic activity five days a week, or to a control group in which habitual activity (or lack thereof) was maintained, for a period of 13 weeks. The primary study outcome was insulin sensitivity, a potent marker of Type 2 diabetes risk; and secondary measures included fitness, and fatness.
Both doses of physical activity significantly improved insulin sensitivity, suggesting diabetes prevention over time. The 40-minute dose exerted a greater effect, but 20 minutes a day was clearly enough to matter.
The higher dose of activity was more effective than the lower at reducing weight and body fat, but both were significantly better than control. And in the case of fitness, measured formally with peak oxygen consumption, both doses were comparably effective, and both much better than control, i.e., doing just about nothing.
So while more exercise is better, some — and a rather small “sum,” at that — can do a remarkable amount of good. If we know — and it seems we do — that fitting 20 minutes of activity in during every school day can be enough to prevent diabetes in a large and growing percentage of our kids, it’s hard to believe we would fail to act on that knowledge.
That much more so when we consider that a daily dose of exercise is likely to enhance academic performance, rather than interfere with it. “Sound mind, sound body” should sound familiar, because it’s the kind of sensible advice our grandparents gave us. Science now points in the same direction, it just took longer to get there.
