Is correct…only do you have to recruit a motor unit/muscle fiber to make it grow, you must create enough fatigue and damage to it?
Only longer sets(1016RM for set) would cause more fatigue in the ST fibers, thus would stimulate them more. (???)
Slow Twitch fibers are not strong enough to continue to produce enough force to lift the heavy weight, when the fast twitch fibers are fatigued then the continuation of the exercise is impossible. However the slow twitch fibers were not fatigued (they are just not strong enough to allow you to continue the set) so they are not stimulated (or they are but to a small degree). (???)
Knowing aticles/studi on this topic?
