Excerpts from an article by Jonathan Myers, PhD; published in “Circulation”, by the American Heart Association.


As many as 250,000 deaths per year in the United States are attributable to a lack of regular physical activity. In addition, studies that followed large groups of individuals for many years have documented the protective effects of physical activity for a number of non-cardiovascular chronic diseases, such as non-insulin dependent diabetes, hypertension, osteoporosis, and colon cancer.


In contrast, we see a higher rate of cardiovascular events and a higher death rate in those individuals with low levels of physical fitness.  Even midlife increases in physical activity, through change in occupation or recreational activities, are associated with a decrease in mortality. Despite this evidence, however, the vast majority of adults in the United States remains effectively sedentary; less than one-third of Americans meets the minimal recommendations for physical activity.

(*) One MET, or metabolic equivalent, represents an average person’s resting metabolism or oxygen uptake. As you go through your daily life, most tasks require an energy expenditure that is less than three (3) times your resting level, or three METs. METs offer a quick screening measure in evaluating your cardiovascular fitness.


This article is a bit lengthy for Trax News, but contains a wealth of information.  When it comes right down to it, your health sets the stage on which you will live your life!
