According to Simmons and Brown (2013), the sedentary lifestyle is one of the 5 major risk factors for cardiovascular disease and causing over 3 million deaths each year in worldwide. In the past 10 decades, there are numerous scientific reports pointed out the relationships between cardiovascular health and physical activities. Based on the US Surgeon General’s report on Physical Activity and Health (1997), evidence from this report shows that more active individual tends to develop less coronary heart disease (CHD) than sedentary counterparts. Therefore, regular activities have been proved to have a positive effect on many of established risk factors for cardiovascular disease. This essay, firstly, will delineate the relationship between cardiovascular health and endothelial function. And follow by discussing how physical activities benefit cardiovascular health and endothelial function. The endothelium is a type of epithelium that lies on the interior surface of lymphatic vessels and blood vessels, which are vascular endothelial cells and lymphatic endothelium. Vascular endothelial cells have different functions, such as helps to regulate blood clotting, maintain the vascular homeostasis, produce vasodilating properties substances or hormones (e.g. NO) to control the blood pressure, and repair the diseased or damaged via injection of blood vessel cells. Evidence from many scientific studies shows that there is a strong association between endothelial dysfunction and
