Aerobic exercise promotes cardiovascular health, while physical inactivity is associated with increased morbidity and mortality.
Exercise causes the heart to pump blood into the circulation more efficiently as a result of more forceful and efficient myocardial contractions, increased perfusion of tissues and organs with blood, and increased oxygen delivery.
Aerobic exercise trains the heart to become more efficient.
Aerobic conditioning exercises, such as running and swimming, train the heart and lungs to pump blood more efficiently, allowing more oxygen to get to muscles and organs.
Exercise is protective against metabolic syndrome, lowers blood pressure, works against blood clotting, and lowers stress, all of which contribute to improved cardiovascular health.
Too much exercise can be harmful, and may cause cardiac hypertrophy or sudden cardiac death in those with certain genetic characteristics.
aerobic exercise: A process whereby one trains the heart and lungs to pump blood more efficiently, increasing delivery of oxygen to muscles and organs.
metabolic syndrome,: A complex disease, characterized by lack of exercise and high levels of adipose tissue, that turn causes many other cardiovascular and endocrine diseases.
Exercise has been shown to protect against nearly every type of chronic acquired cardiovascular disease. A sedentary and inactive lifestyle is associated with greater risk for hypertension, cardiac hypertrophy, atherosclerosis, and myocardial infarctions, due to the metabolic changes that accompany a sedentary lifestyle. The physiological benefits of exercise on the heart include increased blood filling and pumping ability and improved oxygenation.
