Single fibre visco-elasticity in EDL muscle from adult Actn3KO mice. a Example trace of ‘strain-jumps’ of increasing percentage of L0 amplitudes quickly applied to the fibre. b Each sudden stretch is answered by an instantaneous increase in restoration force FR to a new maximum Fabs (c) before exponentially relaxing to achieve a new steady-state level with relaxation amplitude Frelax (d) and a time constant trelax
