“…Muscle fibers are activated by the central nervous system through electrical signals transmitted by motoneurons. A single motoneuron together with the muscle fibers that it contacts is called a motor unit which is the smallest functional subdivision of the neuromuscular system (Moritani, et al 2004) The central nervous system controls the activation of motor units to optimize the interaction between our body and the surrounding environment. When the motor units are activated by the central nervous system, they produce an action potential trains of the active motor units add together to generate the interference EMG signal.…”

“…São tradicionalmente classificadas em 3 tipos (Moritani et al, 2004) (Burke, 1981;Moritani et al, 2004 Uma contração muscular é acionada por impulsos nervosos conduzidos pelos axônios das MUs às suas respectivas fibras musculares, produzindo os potenciais de ação que trafegam ao longo destas fibras (Basmajian e DeLuca, 1985;Bear et al, 2008).…”

“…Nestas condições, o potencial interno (potencial de repouso) da membrana da fibra muscular pode apresenta-se entre -65 e -70 mV em relação ao terra, ou entre -85 e -90 mV em relação ao exterior da membrana -fibras de contração rápida, em geral, com potencial mais próximo do zero -, encontrando-se esta polarizada (Kamen e Gabriel, 2010 (Moritani et al, 2004).…”
