This paper describes a method of numerical analysis of muscle force in a human upper limb during flexion of the forearm joint. Muscles were modeled by a straight line from the origin to the insertion. The optimization method of sequential quadratic programming was applied to this analysis. Restrictions in the object function of the optimization method were selected toexpress the muscle properties acting only in the direction of the contraction. Therefore, the synergist and the antagonist could be separated analytically. Moreover, the distribution of muscle force in the wide area of the muscles-bone adhesion depends on elbow joint angle. Therefore, the muscle-bone adhesive point was also determined to minimize the objective function. The effectiveness on this analysis were confirmed by experiments using electromyography.
