Skeletal muscle has a complex hierarchical structure which is mainly composed of myofibers and the surrounding extracellular matrix (ECM) including endomysium, perimysium, and epimysium. To produce movement, force generated by individual myofibers has to be transmitted to the tendon. Previous studies have shown that many muscle fibers terminate within the fascicle without reaching either ends of the tendon[1,2], in which case force generated has to be transmitted laterally through the ECM to surrounding fibers and then to the tendon. In this study, a two dimensional finite element (FE) model of a single muscle fiber was developed to determine the effects of ECM stiffness and tapered end angles of myofiber on lateral transmission of force in skeletal muscle.
