Never before has the public been more aware of the enormous health and fitness benefits of physical activity, which have been highlighted in both the Surgeon General's report (USDHHS, 1996) and in the Healthy People 2010 study (USDHHS, 2000). The most prominent finding of the Surgeon General's report is that people of all ages can improve their quality of life through a lifelong practice of moderate physical activity.
