Well-designed school-based physical activity and extra-curricular sports programs can have a significant impact on the physical activity levels of young people. However, the inclusive and multi-sport orientation of intramural sports may be a viable option to introduce more children to a wider variety of sports. This purpose of this project is to assess the impact of a school athletics policy on students' attitudes and motivation toward sport and physical activity over time and to determine if student's daily physical activity varies by school sport policy. Data will be collected in four middle schools in Raleigh, NC using online surveys, objective measures of physical activity via accelerometers, and observational measure of physical activity via SOPLAY. Statistical analysis will be used to determine if physical activity of students varies by intramural versus interscholastic sports school policy.
