Initiative Description: Students were randomly assigned to either PA or SC and participated in the assigned intervention 31 min per day, each school day, over the course of 12 weeks. The PA intervention involved continuous activity at a rate that required children to breathe hard, a benchmark used in the PA literature to describe energy expenditure in the moderate-to-vigorous range. PA was structured within age-appropriate activities and games that maintained participants’ interest. The SC program was designed to keep participants sedentary but engaged in classroom-based art projects for the duration of the before-school program.
Study Results: The PA intervention was more effective than the SC intervention at reducing inattention and moodiness in the home context. Less conservative follow-up analyses within ADHD status and intervention groups suggest that a PA intervention may reduce impairment associated with ADHD-risk in both home and school domains
