The Rigid Body Spring Model (RBSM) is extended and applied to prediction of muscle contraction forces around the human hip joint. A cadaver is disected to measure weights and lenghts of its muscles. Every muscle bandle is modeled as a spring, whose stiffness is proportional to its cross-sectional area. Boundary conditions are given to solve as ordinary way of RBSM. Every muscle contraction force is given as a tensile force of its relative spring. Muscle forces and their resultant joint force vector are thus obtained quite easily. This method is expected useful to analyze locomotion systems of living bodies.
