A study in the January/February issue of Child Development suggests that, contrary to popular belief, preschool-aged children are often sedentary in their play, the Los Angeles Times reports. In observing a group of about 540 preschoolers from 24 preschools in South Carolina, researchers recorded and examined almost 265,000, 30-minute segments of the children’s indoor activities and nearly 30,000, 30-minute segments of outdoor activity. During the course of a typical day, 89% of children’s activities were sedentary, 8%were lightly active and 3% were moderately-to-vigorously active.
