Changes in mechanical properties in osmotically compressed skinned muscle fibers of frog.
The mechanical properties of frog skinned muscle fibers were examined in PVP solution. In a high concentration of PVP, the velocity of isotonic shortening and lengthening decreased remarkably and the stiffness increased not only in the activation solution but also in the relaxing solution.
