Fig. 4From: Absence of the Z-disc protein α-actinin-3 impairs the mechanical stability of Actn3KO mouse fast-twitch muscle fibres without altering their contractile properties or twitch kineticsResting length-tension curves and steady-state compliance of EDL Actn3KO and wildtype single fibres. a Specific restoration force (stress) at 140% L0 analysed in WT and Actn3KO fibres. b Steady-state stiffness values vs. strain indicate a slight trend to lower mechanical stiffness in the Actn3KO background compared to the WTBack to article page
