Spheres of physical activity

The spheres of physical activity experience include aspects of everyday life where physical activity is important. In general, the spheres recognize various purposes of physical activity in different contexts. The spheres of physical activity provide a broad basis for assessing the significance and prevalence of physical activity. There are seven spheres of physical activity experience.
