What Is Aerobic Cardiovascular Exercise

Many people engage in regular aerobic exercise such as running, cross country skiing, bicycling, rowing, fast walking, roller blading (in-line skating), distance swimming, and health club aerobic programs. During these activities the resistance against movement is not as great as weight training and the activity is sustained for 15 minutes or longer. Because muscle energy is generated by burning fat and carbohydrate in oxygen required processes mostly, these forms of exercise are termed aerobic. And, because the heart and blood vessels are responsible for delivering the oxygen-endowed blood to muscle, these types of activity are also called cardiovascular exercise.
