Detailed explanation-1: -When you first start strength training, your brain responds by recruiting more and more motor units every time you contract a muscle. As you continue working out, you’re able to generate more force, and your motor units fire at a more rapid pace. This makes your movements more efficient.
Detailed explanation-2: -Motor unit recruitment is a measure of how many motor neurons are activated in a particular muscle, and therefore is a measure of how many muscle fibers of that muscle are activated. The higher the recruitment the stronger the muscle contraction will be.
Detailed explanation-3: -At higher levels of innervation, recruitment is accomplished by the addition of different motor units firing at or above physiologic tremor rate. During slowly graded and ballistic increases in force, motor units are recruited in rank order of their size.
