The brain dictates what percentage of muscle fibers can be used at will. This is a protective mechanism to ensure that the joints are not damaged by utilizing too much strength at once. Muscle spindles and golgi tendon organs supply the brain with the sensor data that allow it to determine what level of strength is appropriate for each situation. Stories of hysterical strength in which mothers lift cars off their children are examples of these protective mechanisms being overridden, allowing the body temporary full access to the individuals strength capacity. In this video, 4 different methods of increasing the conscious activation of muscle fibers (motor unit recruitment) are investigated.
