Abstract

Aim of this study was to evaluate the persistence of the fatigue-induced changes in motor unit (MU) electrical and mechanical properties after a short period of recovery. In 7 subjects the force, EMG and mechanomyogram (MMG) were recorded from m. biceps brachii during a 20 s isometric effort at 80% of the maximal voluntary contraction (MVC), before (test 1) and 10 min after (test 2) an intermittent fatiguing exercise (6 s on - 4 s off cycles at 50% MVC). It resulted that: a) the MVC was 412±90 N (mean±SEM) and 304±85 N in fresh and fatigued muscle, resp. (P
