Physical activity in the prevention of cardiovascular disease

Abstract

Research during the past several decades confirms the health benefits of regular physical activity, including improved cardiovascular function and quality of life, with reduced risks of morbidity and mortality from cardiovascular heart disease (CHD). Health care professionals, including physical therapists, can assist the public by promoting physical activity and describing the type, quantity, and quality of activity that confers health benefits. Participation in vigorous physical activity for at least 30 minutes a day is recommended for cardiorespiratory fitness, but recent studies suggest that physical activity below this level can have benefits in reducing the risk for CHD. This article addresses the relationship between physical inactivity and the financial burdens on health care, the relationship between physical inactivity and the risks of developing CHD in different age groups, the health benefits associated with moderate levels of physical activity, and the amounts and types of physical activities that are needed to reduce the risk of CHD.
