Losing Fat, Gaining Brain Power, on the Playground
Better grades might be found on the playground. A new study of elementary-age children shows that those who were not part of an after-school exercise program tended to pack on a particular type of body fat that can have deleterious impacts on brain health and thinking. But prevention and treatment could be as simple as playing more games of tag.
Most children do not meet the federal health guidelines for exercise, which call for at least an hour of it a day for anyone under the age of 18. Physical inactivity can result in weight gain, especially around the midsection — including visceral fat, a type of tissue deep inside the abdomen that is known to increase inflammation throughout the body. It is also linked to heightened risks for diabetes and cardiovascular complications, even in children, and may contribute to declining brain function: Obese adults often perform worse than people of normal weight on tests of thinking skills.
