If the physiology of muscular contraction is reviewed in the light of internal muscle mechanics, a new approach to the physiology of tendon surgery is opened. Certain internal rearrangements must occur in the structure of the muscle after its range has been lengthened, shortened or changed. In the study of these rearrangements the length-tension curve is of primary importance.

1. FUNCTION OF THE INTERNAL STRUCTURE OF MUSCLE IN THE TRANSMISSION OF FORCE

The muscle fiber is an elastic tissue with physical properties varying greatly between the relaxed and the stimulated, or contracting, state. A length-tension curve may be constructed to express the behavior of the physical property to be emphasized here, namely, elasticity. If a resting muscle were stretched out and its length-tension relations plotted, a curve would be obtained resembling that shown by the dotted line in figure 4. A maximally stimulated parallel-fibered muscle would follow the path shown . . . [Full Text PDF of this Article]
