Factors that Influence the Force of Contraction

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. WebWhen contraction stimuli do not exist and no external force is applied, the muscle relaxes at its resting length.
