SCP-TD comparison: GM muscle tendon complex length. Length of the muscle-tendon complex (ℓ
), normalized for tibia length, plotted as a function of foot plate angle. Mean values (and SE) and third-order polynomial fitted curves are shown. (φfoot plate) is represented as deviation from the neutral position (0°), i.e. with the longitudinal axis of the tibia perpendicular to the foot plate. Note that normalized length is even different for a point at similar foot plate angle (indicated by a dashed rectangle).
