Researchers Just Found A 'Rewind Button' For Muscle Ageing

It explains why exercise is so good for older muscles.

Research has already shown that exercise can help us to live longer – and we’ve written before about the 14 hallmarks of ageing that regular exercise helps to slow down.

Now, a new paper published in the journal Proceedings of the National Academy of Sciences (PNAS) has identified the biological “rewind button” that helps physical activity reverse or prevent age-related muscle loss (sarcopenia).

In this study, researchers found that exercise seems to restore a key balance in muscle cells that gets disrupted as we age.

Why does exercise help to reverse muscle ageing?

Healthy muscles rely on a growth pathway called mTORC1, which is in charge of........
