Increasing physical activity of children during school recess.

Physical activity is crucial for children's health. Fitbit accelerometers were used to measure steps of 6 elementary students during recess. The intervention included reinforcement, self-monitoring, goal setting, and feedback. Steps taken during the intervention phase (M = 1,956 steps) were 47% higher than in baseline (M = 1,326 steps), and the percentage of recess spent in moderate-to-vigorous physical activity was higher during intervention (M = 25%) than in baseline (M = 4%). These methods successfully increased steps during recess and could be used to increase steps in other settings.
