"You aren't going to get better by just sitting around": physical activity perceptions, motivations, and barriers in adults 75 years of age or older.

Despite accumulating evidence of cardiovascular benefits associated with physical activity in older people, sedentary behavior increases with age. Few physical activity research studies focus on underactive adults 75 years and older. In-depth qualitative interviews using open-ended questions explored perceptions, motivations, and barriers to physical activity in 33 previously sedentary or underactive adults age > or =75. Data were analyzed using the NUD*IST (Non-numerical, Unstructured Data Indexing, Searching, and Theorizing) qualitative analysis program. Participants saw sedentary behavior as harmful, considered themselves relatively active, were unsure of amounts of physical activity to do, and welcomed more physical activity information from their doctors. Motivations included health, independence, family, and appearances. Barriers were poor health, lack of time, aging, and adverse environments. Results suggest that people continue to be interested in physical activity as they age, but some misperceptions about physical activity exist. Even with health problems and age, physical activity counseling by doctors is valued and considered helpful by this age group. Copyright 2003 CVRR, Inc.
