Size of study:
Participants’ activity levels across 62 different physical activities were measured. Leukocyte telomere length was then measured using qPCR. Analysis revealed that regular physical activity correlated with significantly longer telomeres that accounted for an additional 9 years less biological aging for the most physically active compared with those that were sedentary. The study’s authors postulated that regular physical activity may reduce disease risk due to the remediation of age related telomeric shortening.
