By responding to subtle shifts in muscle length and phase of activation, muscles modulate limb-substrate interactions by seamlessly adjusting among a variety of roles— acting as motors, struts, springs and brakes [1]. The ability of muscles to rapidly and seamlessly shift mechanical functions depending on context is important for enabling stable locomotor behavior. Here, we investigate the behavior of the human tibialis anterior (TA) during walking using a novel ‘muscle avatar’ approach [2]. In particular, we examine how the biphasic activation and fascicle length behavior of the TA influences the functions of the muscle and the work performed.
