Whether it be a brisk walk around the park or high intensity training at the gym, exercise does a body good. But what if you could harness the benefits of a good workout without ever moving a muscle?
Michigan Medicine researchers studying a class of naturally occurring protein called Sestrin have found that it can mimic many of exercise’s effects in flies and mice. The findings could eventually help scientists combat muscle wasting due to aging and other causes.
“Researchers have previously observed that Sestrin accumulates in muscle following exercise,” said Myungjin Kim, Ph.D., a research assistant professor in the Department of Molecular & Integrative Physiology. Kim, working with professor Jun Hee Lee, Ph.D. and a team of researchers wanted to know more about the protein’s apparent link to exercise. Their first step was to encourage a bunch of flies to work out.
