Tetanized muscle contraction (MuscleContraction).
Description: Simple physiology application, that may be used to analyze tetanized muscle contraction. The program draws the curve
of the shortening velocity and/or the muscle output power as a function of the muscle load, based on either Hill's equation of muscle performance, or
simple cross-bridge kinetics models. With Hill's equation, the user may choose to enter the full parameter list, or to use the one-parameter normalized form.
With cross-bridge kinetics, a choice between a two-state and a three-state model is possible. Concerning the drawing, velocity and power may be displayed on
the same graph or displayed separately. In this latter case, several curves (for different K values) may be displayed on the same graph (possibility to compare
the shape of the curves). Application help and a short introduction to the physiology of muscle contraction (in particular, all formulas used to do the
