A mechanical model and stress-strain response of the biceps brachii under static load

Muscle contraction is a complex phenomenon that begins with chemical processes, continues physiologically, and leads to the production of force. Although force in muscles depends on factors such as temperature, age, gender, race, but most important factor external load applied muscle. Determining effects increased muscle mechanics particular importance for planning exercise activities rehabilitation processes. In this study, different forces stress pressure behavior were examined simplified model biceps. Accordingly, finite element biceps brachii fiber was constructed. The application static loads (2.5 – 100 N) both proximal tendon (one-directional) distal (bidirectional) together investigated. According results, it found directions causes significant increase displacement stress.
