In order to analyze human motions, it is efficient way to use musculo-skeletal model and inverse dynamics. Indeed there is some commercially available softwares which implement musculo-skeletal models to analyze human motions, but models in those softwares doesn't reflect differences among individuals. In this research we propose the way to estimate personal musclotendon parameters and mass properties of musculo-skeletal model, which are necessary for more detail inverse dynamics. Musclotendon paremeters were estimated from EMG data and joint torque which were measured with MYORET torque meter. Mass properties were estimated using principal component analysis of a database which contains sectional data of 100 people. Finally we verified these estimated parameters using inverse dynamics and got better result than one with conventional parameters which are used generally so far.
