Modeling the force-length-velocity-activation relationship 正如我们所看到的,肌肉产生的力量取决于其纤维的长度和速度。肌肉力量也受到运动单元发射频率和招募的调节。在最大激活状态( a(t) = 1 )时,力量、长度和速度之间的功能关系可以用图4.17所示,其中在特定长度和速度下的产生力量的能力简单地是对应的力-长度...
Definition The force-velocity relationship describes how muscle force depends upon the velocity of movement or vice versa . Characteristics Quantitative Description The seminal experiments of A.V. Hill showed that the velocity of shortening in actively contracting skeletal muscle depended upon the force ...
We investigated the mechanism underlying the differences in the FV relationship. We hypothesized that for a given force, Vmax is greater during work loop experiments because during stretch a muscle can store elastic energy that can be recovered upon shortening. It is possible that the giant elastic...

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. ...
