Physical Activity and Adherence

  • Kelli Allen
  • Miriam C. Morey


There is abundant evidence supporting the health benefits of physical activity, including reduced risk for cardiovascular disease, stroke, some cancers, type 2 diabetes, osteoporosis, hypertension, high cholesterol, obesity, osteoarthritis, and all-cause mortality [1]. Physical activity is also associated with improved psychological health and functional status, as well as reduced health-care expenditures [2]. It has been estimated that the direct costs of physical inactivity account for approximately $24 billion, or 2.4% of US health-care expenditures [1, 2]. Furthermore, about 12% of all deaths in the USA can be attributed to physical inactivity [3].
