Net excitation of the motor unit pool varies with load type during fatiguing contractions.

abstract：INTRODUCTION:Although there are numerous protocols to adjust the amplitude of the Hoffmann reflex (H-reflex) relative to the size of the direct motor response (M-response), the optimal stimulating location has not been described. We sought to determine the optimal positioning of the stimulating cathode when evoking the...
