The physical benefits of cardiovascular training, is exercise of relatively low intensity that depends primarily on the aerobic energy generating process. The physical benefits of cardiovascular training, literally means living in air, and refers to the use of oxygen to adequately meet energy demands during exercise via aerobic metabolism. Generally, light to moderate intensity activities, that are sufficiently supported by metabolism can be performed for extended periods of time. The physical benefits of cardiovascular training, can be contrasted with anaerobic exercise, of which strength training and short-distance running are the most salient examples. The two types of exercise differ by the duration and intensity of muscular contractions involved, as well as by how energy is generated within the muscle. In most conditions, the physical benefits of cardiovascular training, occurs simultaneously with exercises because the less efficient anaerobic metabolism must supplement the aerobic system due to energy demands that exceed the cardiovascular system’s capacity.
