Abstract: In this study, we measured the ankle joint torque with the electromyogram (EMG) and the mechanomyogram (MMG) on several positions of the human ankle during isometric dorsiflexion. We measured maximum voluntary contraction torque (MVC) and ramp contraction between dorsiflexion angle of 30 degrees and a planter flexion angle of 40 degrees. MVC was the greatest in the neutral position. The RMS amplitude of EMG was similar at the neutral position and planter flexion of 40 degrees and was bigger at dorsiflexion of 30 degrees. And the inflection point at 60-75 %MVC of the RMS amplitude of MMG was shifted to higher torque with planter flexion. It is thought that these results reflected a muscle activity caused by this length.
