Interventions to promote physical activity by older adults

Physical inactivity has been established to be an independent risk factor for a range of chronic diseases and con-ditions that threaten the health of the nation. However, only a minority of the population is currently meeting the recommended levels of regular physical activity, which have been linked with important health and quality-of-life benefits. Older adults are at particular risk for leading sedentary lifestyles. This article provides an over-view of factors associated with physical activity for older adults and also describes potentially promising inter-ventions for promoting regular physical activity in this growing population segment. Examples of interventions undertaken at personal and interpersonal as well as broader levels of analysis (e.g., environmental) are provided. Major issues currently facing the field are discussed, including the ongoing challenge of developing assessment tools that are sensitive to the more moderate-intensity physical activities favored by older adults and the formida-ble task of combining clinical approaches with environmental and policy strategies aimed at combating this pub-lic health problem. ORE than 4 decades of epidemiological, clinical, and laboratory-based research have established the role of regular physical activity as an important determinant of health and functioning as people age (1–3). However, th
