Abstract
The objective of this study was to propose the optimal gait for muscle training during walking in water. First, the simulation method, which has been developed by the authors, was briefly described. The method consists of the inverse dynamics analysis part, which is a variation of the authors' swimming human simulation model SWUM, and the two-dimensional musculo-skeletal analysis part. Second, the evaluation index for the muscle training and the penalty index for the load on the joint were defined. Third, various gaits were analyzed by the simulation method. From the analysis, two gaits accompanying the large joint motions at the hip and knee were selected as the optimal gaits, by comparing the evaluation and penalty indices.
