Physical activity has been shown to reduce the risk of premature death and chronic conditions and improve health risk factors, physical —tness, and functional capacity (Haskell et al. 2007; U.S. Department of Health and Human Services 2008). Accordingly, physical activity has been identi—ed as a critical element of healthy aging (Kesaniemi et al. 2001), a term used to characterize optimal physical, mental, and social well-being in older adults. To achieve optimal health, it is recommended that all healthy adults participate in both aerobic and muscle-strengthening activity (Haskell et al. 2007) and avoid excessive time in discretionary sedentary pursuits. Engaging in activities that result in improvement in other facets of physical —tness (e.g., exibility and balance/coordination) is also important. However, in 2007, less than half (49.3%) of U.S. adults met the guidelines for physical activity (Centers for Disease Control and Prevention 2008).
