Nesses pacientes, o estudo da condu\u00e7\u00e3o nervosa motora ap\u00f3s per\u00edodo de esfor\u00e7o muscular m\u00e1ximo ou ao est\u00edmulo repetitivo pode revelar achados caracter\u00edsticos da doen\u00e7a. Descrevemos o caso de um homem de 37 anos com sintomas de intoler\u00e2ncia aos exerc\u00edcios, fadiga muscular e c\u00e3ibras no in\u00edcio da atividade f\u00edsica com a presen\u00e7a do fen\u00f4meno de \"second wind\". O estudo da condu\u00e7\u00e3o nervosa motora apresentava redu\u00e7\u00e3o na amplitude do potencial de a\u00e7\u00e3o muscular composto ap\u00f3s esfor\u00e7o de 30 e 90 segundos em nervos mediano, ulnar e fibular profundo e decremento ap\u00f3s 200 est\u00edmulos a 40 Hz em nervo fibular profundo. A eletromiografia de agulha apresentava padr\u00e3o miop\u00e1tico e durante o exerc\u00edcio isqu\u00eamico n\u00e3o se evidenciou sil\u00eancio el\u00e9trico.
