some believe muscle fibre types can be modified 11b to IIa to I by calcium signaling pathways that involves calcineurin.
so my thought is could it go the other way? after a muscle is repeativly trained could this modify the fibre type to be stronger and therefore resistant to damage leaving only newer muscle growth available to break down?
