Telomeres are the ‘caps’ at the end of each chromosome that work like the plastic aglets on the end of your shoelaces, but rather than preventing your shoelaces from unravelling, telomeres act to prevent your DNA from fraying and slow aging.Ĭells replicate themselves by division, but every time a cell divides, its telomeres become a a little bit shorter, until a point is reached where they are so short that the cell can no longer divide. Researchers from the University of Leicester at the National Institute for Health Research (NIHR) Leicester Biomedical Research Centre studied genetic data from 405,981 middle-aged UK Biobank participants and found that a faster walking pace, independent of the amount of physical activity, was associated with longer telomeres. Of course, we have seen wearables growing in popularity as people seek to take control of both their fitness and their longevity it’s interesting to see this data that not only confirms the positive benefit walking can have to slow down aging, but confirms it at a cellular level. Longevity.Technology: While the physical, mental, social and health benefits of walking have been well-documented, this study, which is published in Communications Biology, is one of the first of its kind to compare genetic data with both self-reported walking speeds, as well as actual measurements of movement intensity from wearable activity tracking devices worn by participants. The researchers estimate that a lifetime of brisk walking could slow aging and lead to the equivalent of 16 years younger biological age by midlife.
A new study of genetic data of more than 400,000 adults has revealed a clear link between walking pace and slow aging through a genetic marker of biological age.Ī team of researchers based at Leicester in the UK have confirmed a causal link between walking pace and leucocyte telomere length (LTL) – an indicator of biological age.
