Very little exercise in today's PE classes, plenty of blame to go around

Feb. 11, 2003 -- Kids are parked on the couch at home -- and they're not getting much activity at school, either. Most third graders get less than 25 minutes of exercise a week in school programs, a new study shows. Some are getting next to no activity at all.

"It's a snapshot of what's happening in schools, and it doesn't look great," says Sarah Friedman, PhD, a scientific coordinator for the National Institute of Child Health and Human Development.

Friedman helped lead the study of 648 schools -- and 814 students -- funded by the National Institute of Child Care and Youth Development. The study appears in the February Archives of Pediatrics and Adolescent Medicine.

It paints a bleak picture of physical education programs in today's schools. Yet, the American Academy of Pediatrics advises a minimum of 30 to 60 minutes a day of physical activity -- "playing outside, brisk walking, low impact sports, even just plain catch," says William F. King, Jr., MD, a professor of pediatrics at Temple Children's Hospital in Philadelphia.

"Exercise has to be a higher priority for society," he tells WebMD. "It's no coincidence that the communities that have very limited access to green space are also communities where the obesity epidemic is most intense."

In their study, observers tracked the activity of children as they participated in school PE classes.

"Some children don't have any PE classes at all, 30% had class once a week, and the large majority -- 45% -- have it only twice a week," Friedman tells WebMD. "The number of schools that comply with the idea of five times week of PE per week is very small -- 6% of schools. Only 3% of children had PE classes four times a week."

On average, children had two PE classes a week, totaling 69 minutes. In their classes, they spent 10 minutes playing games, five minutes in "fitness exercises" like calisthenics, five minutes hearing teacher's explanations, and seven minutes forming lines and waiting.

Students engaged in only about five minutes of vigorous physical activity and 12 minutes of moderate to vigorous physical activity.
