Aerobics for the Heart

Over 20 years of research has shown that aerobic exercise is one of the best things you can do for your health and well-being. Aerobic exercise improves the efficiency of the heart, lungs and blood vessels as well as the efficiency of the metabolic enzymes that regulate the conversion of stored energy in muscle cells.

Oxygen can only be supplied to the muscles through the red blood cells. When muscles are being used in exercise, the heart must pump more blood through the body to supply the extra need for oxygen. This, in turn, causes the lungs to be expanded to fill the need of oxygen required by the red blood cells being quickly moved through the body.

Due to the fact that the muscles are requiring more oxygen to create energy, the body naturally increases the amount of oxygen inhaled. The heart rate increases as it pumps the blood through the system faster to supply the necessary oxygen to each muscle. Thus the circulation of the blood is greatly increased.

This increase in circulation has a twofold benefit to the body. First, an abundant supply of oxygen is taken not only to the muscles, but also to every part of the system.

And second, the blood is circulated through the eliminating organs at a much greater amount, thus resulting in an increase in the elimination of the body's wastes. Both of these are essential for good health and healing.
