I'm currently taking the NSCA course, and i'll be posting up questions i have every now and then.

Suffice to say ill be bumping this thread over the course of the next month with new questions.

My first one pertains to types of muscle

Type 1 muscle and Type 2 A / B muscle.

I know

Type 1 is a type of fiber that fights fatigue for an extended period of time

Type 2 A is an intermediate between anaerobic and aerobic exercise

Type 2 B is extremely good at anaerobic exercises

So my question is as follows.

if your a runner and start lifting are you converting muscle type 1 into muscle type 2 A? or creating completely new muscle fibers?
