Can muscle fibers increase in number
WebSkeletal muscle cells are however unique in the body in that they can contain multiple nuclei, and the number of nuclei can increase. Cortisol decreases amino acid uptake by muscle tissue, and inhibits protein synthesis. The short-term increase in protein synthesis that occurs subsequent to resistance training returns to normal after ...
