The aim of this study was to develop the training method for the selective muscle strengthening using the mechanical impedance load. One male subject completed fully elbow flexion in two loading manners which were the isoviscous load (3.0,5.0,8.0,12.0,20.0,30.0[Nm/s/rad]) and the mechanical impedance load. The mechanical impedance load of this study was the load changing from isoviscous load to elastic load during the motion. The comparison of these results implied the possibility of the selective muscle strengthening using our proposed training method.
