The health benefits of triathlon training
A good working cardiovascular system is essential to our health. Our arteries are the blood vessels that take blood away from the heart and toward the muscles. It is very important for the arteries to work properly so they can bring nutrient-rich blood to our organs. When we are young, our arteries are elastic, flexible and open. As we age, however, our arteries become thick and stiff. Through a process called atherosclerosis, the arteries become blocked up with a substance called plaque. This plaque is the buildup of fats such as cholesterol, triglycerides and phospholipids. Plaque restricts blood flow to organs in the body, contributing to heart disease, which, according to the Centers for Disease Control and Prevention, is the leading cause of death in the United States (National Center for Health Statistics, 2016).
