This is when we try to lift an object much heavier than we can handle, as the cheerleader shown in the question above tried to do. It seems that the mechanism of this contraction lies in the fact that the energy that would normally be exhibited as external mechanical work is used in the structural rearrangement of the fibers, ie the fibers shorten and the tendon lengthens, and some of the energy dissipates into heat. .
