The stiffness was defined as initial rise of tension versus time at the beginning of linear stretch (test stretch) of equilibrated muscle. Effects of a sinusoidal conditioning stretch on the stiffness depended on the amplitude of the oscillation but were almost independent of the duration of the conditioning. Against a rapid decrease in stiffness caused by stretch, the recovery of stiffness during maintenance at a constant length was gradual. It has been established that a hump of the muscle tension usually observed at the beginning of linear stretch is caused by the initial great stiffness of muscle fibers and the following rapid decrease of it.}, pages = {131--137}, title = {Change in Stiffness of Mammalian Muscle Fibers Caused by Stretch}, volume = {33}, year = {1970} }
