Considerable attention has been directed to the characteristic force-velocity relation discovered by A. V. Hill in the study of muscle kinematics. Models of contractile process were tested on the basis of their compatibility with the Hill equation. However, almost all the isotonic data have been ...
The neurochemical signal sent to the muscle is then propagated through the entire muscle fiber down to the smallest function unit, which is the sarcomere. At the sarcomere level, calcium binds to troponin on the actin myofilament and allows the actin-binding site to be ...

The steady-state force-velocity curve thus obtained was analogous to the double-hyperbolic force-velocity curve of single muscle fibers. The unloaded velocity of bead movement was 1.6-3.6 microns/s (20-23 degrees C), while the maximum "isometric" force generated by the myosin molecules on the...
It is important to note that cardiac muscle fibers do not operate on a single force-velocity curve. This relationship is altered by changes in both preload and inotropy. The former shares some similarities with skeletal muscle; the latter, however, is unique to cardiac muscle. ...
Ifα, m, h, andHare measured, one can compute the muscle forceM: (E#2.4)M=hH/msinα Muscle tension during motion The summation of active and passive tension within the muscle also appears during motion, when muscle length changes. The higher the velocity of muscle contraction, the faster...
The capacity of a muscle to produce force is known to depend on the history of contraction.1, 2, 3 Contraction histories that lead to an increase in force compared to the force predicted by the force–length (FxL) and force–velocity relationship have been of special interest to the scienti...
Velocity-Dependent Changes in Electrical Efficiency of the Leg Extensors during Eccentric Isokinetic Muscle Actions The mechanisms underlying velocity-specific decreases in torque production during eccentric muscle actions remain unclear. Therefore, the purpose of the pr... Hill, Ethan C.Housh, Terry J...
