An observational evaluation of move-to-improve, a classroom-based physical activity program, New York City schools, 2010.

Introduction: Few children in the United States achieve the recommended 60 minutes of physical activity per day. Identifying successful interventions that increase physical activity for children is critical. This observational study evaluated the effects of Move-To-Improve (MTI), a classroom-based physical education program designed for kindergarten to third-grade teachers in New York City public schools.
