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. But little has been known about visceral fat and brain health in children. For a soon-to-be-published study, researchers from Northeastern University in Boston and the University of Illinois at Urbana-Champaign tracked hundreds of 8-to-10-year-old children in a nine-month after-school exercise program in Urbana. Every day, one group of children played tag and other active games for about 70 minutes. The subjects in a control group continued with their normal lives, with the promise that they could join the program the following year. All ... Link to the full article to read more
