Stronger Cells

“Both short bursts of exercise and lengthy endurance tests can boost cell health, two studies report.  Stress can shorten bits of DNA called telomeres, which cap and protect chromosomes.  In one study, short telomeres were observed in sedentary postmenopausal women who reported being stressed out, but those who vigorously exercised for 40 minutes over three days had long, healthy telomeres despite high stress.  Another study showed that cells may live longer in marathon runners.  Researchers found that a natural process called apoptosis, or programmed cell death, was suppressed in men who had just run a morning marathon.”  Sources: PLoS ONE, May 2010; BMC Physiology, May 12, 2010
