Exercise and Epigenetic Aging: Turning Back the Clock

This video explores the concept of biological age, which differs from chronological age by reflecting the body's actual internal health and ageing processes, measured through epigenetic clocks that analyse DNA methylation patterns. It highlights research on professional footballers showing that intense exercise can lead to temporary improvements in biological age markers immediately after a match, particularly in clocks like GrimAge2 and FitAge. While these effects are short-lived and most pronounced in elite athletes, the text suggests that consistent exercise, alongside other healthy lifestyle choices, can contribute to a slower overall biological ageing pace. This indicates that ageing is not fixed but rather flexible, with lifestyle playing a significant role in influencing how quickly our bodies age.
