Ten healthy male students (age 22.1+2.3 years), without neurological disorders, volunteered for the study. Muscle fatigue of the first dorsal interosseus muscle was studied during repeated isometric voluntary contractions until exhaustion. Transcranial magnetic stimulation was used to elicit motor-evoked potentials and mechanical responses in the exercised muscle. The averages of 6 responses were analyzed pre-exercise, every 25 contractions during the exercise and during the recovery phase. The average of isometric contractions until the fatiguing of a subject was 175 repetitions. During the protocol, amplitudes of mechanical as well as electrophysiological responses changed significantly (P
