O-39 Force-velocity curves for powerful and endurance athletes: effect of muscle fibre type compositionThe relationship between force and the velocity at which a load can be moved is known as force-velocity (F-V) curve. Methods that control strength training intensity based on F-V curves have...

在第五章,我们将观察宏观尺度,了解肌肉如何在身体中排列,以及它们如何与肌腱(tendons)相互作用,肌腱是将肌肉力量传递给骨骼的结构。 Muscle structure 在最基本的层面上,肌肉通过两种长而窄的蛋白质(long, narrow proteins)——肌动蛋白(actin)和肌球蛋白(myosin)之间的相互作用来产生力量。20世纪50年代初,休·赫胥...
Hill believed that the functional significance of these experiments was that an internal viscous resistance within the muscle had to be overcome in order for shortening to take place [ 1 ]. Although this theory proved to be incorrect, the fact that force and velocity are interrelated is ...
FORCE-VELOCITY (F-V) FEATURES OF THE HUMAN VASTUS LATERALIS MUSCLE AT DIFFERENT LEVELS OF NEURAL ACTIVATIONReversal of fatty infiltration of pennate rotator cuff muscle after tendon release is hitherto impossible. The administration of nandrolone starting at the time of tendon release prevents 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. ...
The force-velocity curve was hyperbolic. Using Hill's equation, we calculated the values of P 0 (the maximum force at 1 0, lo being the trachealis muscle lenght at which the maximum active tension develops) and Vmax (the maximum veloxity at zero afterload). They were P 0 = 0.85 ± ...

Its molecular mechanisms remain to be elucidated, however....
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 ...
