Daily, vigorous exercise helps kids get or stay fit

By Kathryn Doyle NEW YORK (Reuters Health) - A nine-month after-school exercise program helped young kids lose body fat and improve heart and lung strength compared to kids who didn't do the program, according to a new trial. It's clear that activity is good for kids, lead author Naiman A. Khan told Reuters Health. "We saw their overall body fat, abdominal fat go down, and in the absence of the program kids actually increased in overall body fat," said Khan, from the University of Illinois at Urbana-Champaign. In the exercise group, kids did 20 to 25 minutes of health-related fitness activities plus 50 minutes of organized noncompetitive games meant to keep their hearts beating at 55 to 80 percent of their maximum heart rate.
