Aerobic exercise is physical exercise of low to high intensity that depends primarily on the aerobic energy-generating process. Aerobic literally means relating to, involving, or requiring free oxygen 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 aerobic metabolism can be performed for extended periods of time.
Aerobic exercise and fitness 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 almost all conditions, anaerobic exercise is accompanied by aerobic exercise because the less efficient anaerobic metabolism must supplement the aerobic system due to energy demands that exceed the aerobic system’s capacity.
Regular aerobic activity such as walking, bicycling or swimming can help you live longer and healthier. During aerobic activity, you repeatedly move large muscles in your arms, legs and hips. You’ll notice your body’s responses quickly.You’ll breathe faster and more deeply. This maximizes the amount of oxygen in your blood. Your heart will beat faster, which increases blood flow to your muscles and back to your lungs.Your small blood vessels called capillaries will widen to deliver more oxygen to your muscles and carry away waste products, such as carbon dioxide and lactic acid.So aerobic exercises are of utmost importance for a man to sustain healthy life.
