63 post-menopausal women
Among the study’s non-exercisers, those with a one unit increase in the Perceived Stress Scale had a 15-fold increased chance of having short telomeres. However, the study’s exercisers’ perceived stress was not related to their telomere length. This conclusion led the study’s authors to hypothesize that vigorous activity buffers the negative effects of high stress on telomere length.
