It is an aerobic exercise that helps increase heart function during exercise. When older adults swim, their hearts become stronger, larger, and more efficient at pumping blood throughout the body with regular exercise. Exercise can help increase blood flow which in turn reduces the risk of coronary heart disease (Carefect, 2012). In addition to this, it actually reduces inflammation of the heart by preventing fat accumulations or the development of plaques in the arteries and blockage of the capillaries. Additionally, it helps increase the metabolic rate through regular exercise with fast and medium speed intervals, which helps older adults become more energetic and healthy. Additionally, according to Dr. Hirofumi Tanaka, director of the University of Texas Cardiovascular Aging Research Laboratory, he found substantial evidence that consistent swimming increases the control of blood sugar levels in the body, which reduces the possibility of diabetes (as quoted by Hutchinson,
