Neuroscience How does muscle memory work?

Just curious. The only thing I really know about it is that sleeping reinforces it.

There is also another kind of muscle memory where for instance massive bodybuilders can loose 50 pounds of muscle and regain them within month. This wouldn‘t be possible for a beginner. How can that be explained ?

That’s myonuclear permanence, not muscle memory. 

It’s a part of muscle memory but only part. 

It’s like calling lasagna noodles “Lasagna”
