For kids, short bouts of intense activity with rests in between might be the ideal exercise prescription. In a study of 46 third graders, 22 took part in a high-intensity interval training program in addition to regular school physical education. The other 24 kids participated in the phys ed class but rested while their classmates did the interval training. Outside the program, all kids got about the same amount of physical activity. After three months, systolic (top number) blood pressure improved in the kids who did the short exercise bursts but didn’t change much in the other kids. To keep your kids active, try short bursts of high-energy activity, such as relay races and dancing.
