Abstract: The main aim is to create a computational three-body segment model of an upper limb of a human body for determination of muscle forces generated to keep a giv en loaded upper limb position. The model consists of three segments representing arm, forearm, hand and of all majo r muscles connected to the segments. Muscle origins and insertions determination corresponds to a real anatom y. Muscle behaviour is defined according to the Hill-type muscle model consisting of contractile and viscoelastic element. The upper limb is presented by a system of three rigid bars connected by rotational joints. The whole limb is fixed to the frame in the shoulder joint. A static balance problem is solved by principle of virtual work. The system of equation describing the musculoskeletal system is overdetermined because more muscles than necessary cont ribute to get the concrete upper limb position. Hence the mathematical problem is solved by an optimization method s earching the least energetically-consuming solution. The upper limb computational model is verified by electromyography of the biceps brachii muscle.
