Exercise Appears To Reduce Cellular Aging Caused By Stress

May 27, 2010

Researchers in the US found that brief vigorous exercise can reduce cellular aging by preventing the shortening of telomeres due to stress.

You can read about the University of California San Francisco (UCSF) study in a paper published online in the open access journal PLoS ONE on 26 May.

Co-lead investigator, Dr Elissa Epel, an associate professor in the UCSF Department of Psychiatry, said in a statement that:

“Telomere length is increasingly considered a biological marker of the accumulated wear and tear of living, integrating genetic influences, lifestyle behaviors, and stress.”

“Even a moderate amount of vigorous exercise appears to provide a critical amount of protection for the telomeres,” said Epel.

Telomeres are protective strips of DNA that cap the ends of chromosomes and stop them unravelling, not unlike the plastic sheaths on the ends of shoelaces…more
