Abstract des Autors

Two groups of male volunteers maintained a submaximum isometric contraction of the elbow flexors to exhaustion. During the endurance session, each subject was required to exert a force equal to 50 % of his maximum voluntary strength and to rate subjectively the increasing intensity of pain resulting from the isometric pull. Continuous recordings of electromyographic activity of the biceps muscle were accomplished through standard surface electrode techniques. The experimental group was provided with direct auditory feedback of the EMG was provided, the level of muscle activity required to sustain the contraction was significantly reduced. These results suggested that auditory EMG provided a situation in which the endurance task was accomplished with greater efficiency. Verf.-Referat
