The purposes of this study were to design the concept the outer skeleton type of ergometer simulating the human muscular characteristics and to evaluate the exercise work load characteristics in wearing of this ergometer. The Hill's equation which approximated the relationship between force and velocity in muscular contraction was adopted for the ergometer as the human muscular characteristics. As the concept design of the ergometer, the human muscular simulating drum mechanism approximated following formula was developed ; ω={V_m/[Lcos(π/8-θ)]}={V_p/[rcos(π/8-θ)]} where Vm was torque as an exercise work load against the subject, L was diameter of the drum mechanism, r was length which sliders could move and Vp was the force the subject output. The experiment assuming in wearing this outer skeleton type of ergometer was done for evaluating the exercise work load characteristics against the subject using EMG. EMG was transformed to the integrated EMG. From this result, it was understood that the exercise work load was amplificated using this mechanism
