San Francisco, CA, United States (AHN) - New research suggests exercise can lessen the impact of aging, even at the cellular level.

University of California, San Francisco scientists say vigorous exercise for as little as 42 minutes a day for three days can protect people from the effects of stress by lessening its impact on the cellular structure known as telomeres.

Telomeres are very small pieces of DNA that promote genetic stability and act as protective sheaths by keeping chromosomes from coming apart. In a statement, the researchers compared telomeres with the plastic tips at the ends of shoelaces,

Scientists have linked damaged or short telomeres to several health problems, including coronary heart disease, diabetes and death.

Telomere length is lessened and damaged by wear and tear brought on by living, lifestyle choices and stress.

The study is published in the Public Library of Science journal ONE.
