Exercise Holds Off Aging

Physically active people have cells that look younger on a molecular level than those of couch potatoes, according to research that offers fundamental new insight into how exercise may help stave off aging.

Researchers have found that exercise appears to slow the shriveling of the tips that protect bundles of genes inside cells, perhaps keeping frailty at bay. Being physically active reduces the risk of heart disease, cancer and other diseases, potentially extending longevity. Researchers examined structures inside cells known as telomeres. They are using telomere length as a marker of biological aging. Telomeres cap the ends of chromosomes, the structures that carry genes. Every time a cell divides, telomeres get shorter. When telomeres get too short, cells can no longer divide. Scientists believe that aging occurs as more and more cells reach the end of their telomeres and die - muscles weaken, skin wrinkles, eyesight and hearing fade, organs fail and thinking clouds.

In Chinese medicine, exercise stimulates healthy cellular activity in all the body’s organs. Cardiovascular exercise dramatically increases oxygen levels in the body. Abundant oxygen seems to be the catalyst for a cascade of beneficial physical activities that lead to delayed aging. Both acupuncture and Chinese herbal medicine can minimize those deficiencies responsible for premature aging.
