Muscle modeling
Muscles are the actuators of living bodies. They are activated by the central nervous system (CNS) by a
complicated electro-chemical process. Determining the activation that realizes a desired movement requires
an extremely intricate control algorithm. The CNS is superior to any computer man has made in this respect.
AnyBody mimics the workings of the CNS by computing backwards from the movement and load specified
by the user to the necessary muscle forces in a process known as inverse dynamics. To do so, the system
must know the properties of the muscles involved, and this is where muscle modeling comes into the
picture.
AnyBody contains three different muscle models ranging from simple to more complicated physiological
behavior. The simplest model just assumes a constant strength of the muscle regardless of its working
conditions. The more complicated models take such conditions as current length, contraction velocity, fiber
