Muscle Contractions: What Are They And How Do They Work?

WebHowever, even when generating the maximum force possible, we are only able to use about 1/3 of our total motor units at one time. Normally they will fire asynchronously in an effort to generate maximum force and prevent the muscles from becoming fatigued. As fibers begin to fatigue they are replaced by others in order to maintain the force. WebStep-by-step explanation. First, twitch, a one-time contraction. Second, wave summation, continuous wave of muscular contractions to increase the power of a muscle contraction by reducing the time between impulses so that the muscle fibres do not have time to relax.
