Kids' team sports don't offer enough exercise

LOS ANGELES According to the Physical Activity Guidelines for Americans, kids should be get 60 minutes of physical activity every day. But a new study reported in the Archives of Pediatrics and Adolescent Medicine finds that some kids in organized sports aren't getting the recommended amount of exercise.

After observing 200 kids aged 7- 14 at baseball, softball and soccer practices, researchers found only 46 percent of practice time involved moderate to vigorous physical activity, amounting to about 45 minutes of exercise.

The findings are not indicative of all team sports, but may show that some kids still need more exercise to meet minimum requirements.
