Just three months of daily, vigorous physical activity in overweight children improves their thinking and reduces their diabetes risk, researchers say.
“Is exercise a magic wand that turns them into lean, healthy kids? No. They are still overweight but less so, with less fat, a healthier metabolism and an improved ability to handle life,” says Dr. Catherine Davis, clinical health psychologist at the Medical College of Georgia and lead investigator.
Looking at the children’s insulin resistance, a precursor of type 2 diabetes in which it takes more insulin to convert glucose into energy, researchers found levels dropped 15 percent in the 20-minute exercise group and 21 percent in the 40-minute group. The control group stayed about the same.
