Only one quarter of children aged 6 to 15 meet the current guidelines of 60 minutes of moderate physical activity per day, said Dr. Russell R. Pate, chairman of the non-profit National Physical Activity Plan (NPAP) Alliance, which issued the first U.S. report card on Physical Activity for Children and Youth.
"Fifty percent of waking hours are spent in sedentary activity," said Pate, professor in the Department of Exercise Science in the Arnold School of Public Health at the University of South Carolina.
Fitness experts say it is up to parents and policy makers to get their children to be more active.
"It's not about grading the kids," said Dr. Peter Katzmarzyk, a fellow of the American College of Sports Medicine and chairman of the research committee that issued the report card.
"Kids want to be active, if they're given the opportunity." he said. "This is for us to change."
