Vascular Formation
Effect of Regular Exercise on Vascular Function and Cardiovascular Risk in a Sedentary Work Force
This study will evaluate the effects of NHLBI's employee exercise program, Keep the Beat, on blood vessel function. Damage to blood vessels can cause narrowing of the vessels, resulting in reduced blood flow to parts of the body…
