Recent experimental findings suggest that the myosin cross‐bridge theory may no longer be adequate to account for certain basic facts concerning muscle contraction. A newly‐proposed mechanism based on length changes in actin filaments might be the basis for a simpler explanation for how the free energy of ATP hydrolysis can be transduced into work by muscle fibers.
