Aerobic activities are those that use oxygen to help produce energy in the active muscles. The heart, lungs, and circulatory system work together to get oxygen to the cells and to clear the byproducts of metabolism from the muscles. When a person is involved in physical activity on a regular basis, the cardiovascular system and the muscles involved in the activity reap the benefits of improved circulation. Regular aerobic exercise helps the circulatory and muscular systems become healthier and more efficient.
Not all activity is aerobic. The body can produce energy for a brief period (such as during a sprint) without the immediate use of oxygen. To be aerobic, an activity must last more than a few minutes and be performed at a sustainable intensity. Rhythmic exercises are excellent for bringing aerobic systems into play. They work the same muscles repeatedly, so that circulation does not have to switch from one area of the body to another. Exercises that fulfill these requirements include walking, jogging or running, swimming, and cycling. The aerobic classes do have some aerobic benefits but, because of the varied movements, the benefits are of a combined type—some muscular conditioning and flexibility on top of limited cardiovascular improvement. The cardiovascular gains, however, are not as great as those attained through the rhythmic exercises just mentioned.
Aerobic exercise benefits more than just your heart. Low-impact aerobic exercise does not exacerbate arthritis pain. Combined with strengthening and stretching, it improves fitness, decreases depression and pain, and (over the long term) improves function. Since several studies have found that the aerobic capacity of individuals with arthritis is lower than that of individuals the same age without arthritis, this aspect of fitness deserves attention . Health benefits accrue when a person simply transitions from inactivity to moderate physical activity . As physical activity increase (in quantity or quality), the risk of cardiovascular disease decreases.
Some articles distinguish between aerobic activity and aerobic exercise— exercise being a more focused, intense activity. For example, mowing your lawn is an activity that yields some aerobic benefit, but not as much as taking a brisk 30-minute walk produces. The health benefits of aerobic exercise include decreased risk of cardiac and other chronic diseases, normalized blood pressure, controlled body weight, decreased blood sugar and lipids, and decreased stiffness and pain from arthritis.
