Researchers Discover Protein that Can Mimic Exercise's Effects

Researchers of Michigan Medicine discovered that a class of naturally occurring protein called Sestrin can mimic many of exercise's effects in flies and mice.

According to the Eurek Alert report, scientists said that when the creatures (mice and flies in this study) were forced to produce a protein released during a workout, they became extra fit.

In this research, the animals were given the protein, named Sestrin, without doing any exercise at all – and they still gained muscle, became fitter and burned more fat.

The same protein is made in humans and researchers suggested forcing the body to produce it, or making a supplement, could get people fit without them working out.

“Researchers have previously observed that Sestrin accumulates in muscle following exercise,” said Dr. Myungkin Kim, who led the study.

Dr. Kim and colleagues believed the production of Sestrin during exercise was what produced benefits in the body.
