Length-Force Relation of Calcium Activated Muscle Fibers

Mark Schoenberg 1 and Richard J. Podolsky 1

1 National Institute of Arthritis and Metabolic Diseases, Bethesda, Maryland 20014

Calcium activated skinned frog muscle fibers develop a large relative force at a sarcomere length of 1.0 micrometer. Since the normal myofilament lattice is perturbed at this length, regularity of the lattice does not appear to be an important factor in the contraction mechanism.
