Study: Even Some Vigorous Activity Boosts Kids’ Heart Health

Adding 20 More Minutes of Exercise a Day Can Make Big Difference
WebMD Health News

Feb. 14, 2012 -- Kids who exercise vigorously for more than 30 minutes a day may be at lower risk of heart disease than their peers who don’t break a sweat quite as often.

This is true regardless of how much time the kids spent sitting on the couch.

Kids who exercised at a moderate or vigorous pace for more than 35 minutes a day had lower levels of cholesterol, blood fats called triglycerides, blood sugar or glucose, blood pressure, and a smaller waist size than their counterparts who clocked about 18 minutes of vigorous physical activity each day.

High blood pressure and high blood cholesterol levels are known risk factors for heart disease. Once seen only in adults, many of these conditions are increasingly being diagnosed in children because of skyrocketing rates of childhood obesity.

The new study appears in the Journal of the American Medical Association.

“Kids should be active,” researcher Ulf Ekelund, PhD, says in an email. Ekelund is a group leader in the epidemiology unit of the Institute of Metabolic Science of Addenbrooke’s Hospital in Cambridge, U.K.

This includes moderate-intensity exercise such as brisk walking, outdoor play, dancing, cycling, aerobics, ball games, and other sports. "Parents should encourage these types of activities rather than [only] reducing sedentary time.” But the study did not distinguish whether sedentary time was spent in front of a TV as opposed to other non-active activities.
