Abstract:
This manuscript presents a brief summary of the substantial data supporting an inverse relationship between the amount of habitual physical activity performed and a variety of negative health outcomes throughout the lifespan. It points out that despite these data a large segment of the US population remain insufficiently active resulting in a high population attributable risk for chronic disease due to inactivity. The accumulated data support the need for more comprehensive health promoting physical activity policies and programs, especially for the economically and socially disadvantaged and medically underserved.

Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
