An article summarized a study of exercise and aging.

Main point: “Late-life exercise mitigates skeletal muscle epigenetic aging” is another way of saying reversal of aging in mice used in the study.

More about it:

  • “Lab mice nearing the end of their natural lifespan, at 22 months, were allowed access to a weighted exercise wheel.”
  • “The weighted wheel ensured they built muscle.”
  • “When the mice were studied after two months of progressive weighted wheel running, it was determined that they were the epigenetic age of mice eight weeks younger than sedentary mice of the same age—24 months.”

Why it matters:

  • “…when your lifespan is measured in months, an extra eight weeks—roughly 10 percent of that lifespan—is a noteworthy gain.”
  • This is one of a number of studies reinforcing the benefits of exercise and shows you may be able to regain what you lose during aging.
