Velocity sensitivity of yielding during stretch in the cat soleus muscle.
Yielding of muscle force occurs when a muscle is stretched by a sufficiently large amount. A higher velocity of stretch requires a larger stretch to cause yielding, and the preyield stiffness is constant. The yield is attributed to cross-bridge disengagement and the velocity sensitivity to a mechanical filtering of this event.
