To evaluate the dynamic behavior of human body at landing, a link model, a musculoskeletal model or multi-degrees-of-freedom model are generally used. In this study, the relation of these models is investigated. The movements of the reference points on the body and the floor reaction force were measured at landing. A four-degrees-of-freedom (4-dof) model is constructed and the parameters are identified such as to reconstruct the measured reaction force. And a four-link (4-link) model is also constructed and the joint forces and the moments are obtained by the inverse dynamics. It was shown that the joint reaction force from the 4-dof model and the vertical component of the joint reaction force from 4-link model agreed well. The joint reaction force from the link model is constructed by the joint forces and the muscle forces, so that the joint reaction force from the M-dof model can evaluate the joint force and the muscle force.
