Aerobic Exercise, Running
Aerobic exercise improves oxygen consumption by the body. Benefits include strengthening the heart's pumping efficiency, improving circulation, lowering blood pressure, and stimulating the production of more red blood cells for oxygen transport. Aerobic exercise conditions the heart and lungs by increasing the oxygen available to the body and by enabling the heart to use oxygen more efficiently. Exercise alone cannot prevent or cure heart disease. It is only one factor in a total program of risk reduction; examples of other factors are high blood pressure, cigarette smoking and high cholesterol level.
