It is easier to build muscle while we’re young, but keeping muscle mass gets more difficult as we age. Starting around age 30, you naturally begin to lose mass, typically at a rate of 3%-5% per decade ...

Exercise can have benefits at the level of neurons, through chemical and mechanical effects, researchers find. The discovery could inform exercise-related therapies for repairing damaged and ...

Building muscle isn’t as simple as just lifting heavy things and hoping for the best. Gaining muscle is not so much about what you do, but rather how you do it. The same exercise could be used to ...

A hard workout can come back to haunt you. When you wake up the next morning and try to get out of bed, everyday motions like rolling over and standing up can make your muscles whine in pain. You ...

In context: Making robots more biologically compatible has been a challenge scientists have been tackling for years. Until now, they have primarily been able to create lab-grown muscle fibers that ...

The impact of circadian disruption on muscle health and aging has been uncovered. A research team at King’s College London (UK) has uncovered the intrinsic and extrinsic effects that circadian ...

MIT scientists find that motor neuron growth increased significantly over 5 days in response to biochemical (left) and mechanical (right) signals related to exercise. The green ball represents cluster ...
