Brisk walking slows biological aging

If you want to age better, then walk quicker, or those who walk quicker, age slower. That is the result of a recent study of 400,000 UK adults mapped to genetic markers of age by the University of Leicester.

What exactly did these researchers find?

They looked at the telomeres which you may have heard of. These are caps at the end of your chromosomes that protect the chromosome (which houses your DNA). They’re kind of like the caps on shoelaces which stop them fraying. Once these shorten or disappear your DNA is at danger of losing the ability to replicate.

Telomere length seems to be a pretty good indicator of biological age irrespective of how old you are.

And this is where the connection becomes interesting. It seems that fast, or brisk, walkers have longer telomeres, and this can lead to a whopping 16 years younger biological age by midlife. That’s a lot. This is also independent of how much other exercise you get.

The same researchers have also shown previously that as little as 10 minutes of brisk walking a day is associated with longer life expectancy and that brisk walkers can have up to 20 years greater life expectancy than slower walkers.

Though they haven’t been able to fully confirm that faster walking speed will lead to greater life expectancy (in contrast to those who naturally walk faster having a natural longer life expectancy) they do note after this study that it is likely.

So, get yourself walking, briskly. My advice for those in the office to have a 3-minute brisk walk every hour seems also to hold very, very true for this, and other reasons.
