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).
