Modeling method of excitation and contraction processes of fast muscle fibers of skeletal muscle

The invention discloses a modeling method of excitation and contraction processes of fast muscle fibers of skeletal muscle. The method includes the steps of (1) adopting half sarcomere as a unit and building an electrophysiologic mathematic model of fast muscle sarcolemma of the skeletal muscle; (2) adopting the half sarcomere as a unit and building a geometric model of calcium ions circulation; (3) building a mathematic model of a release process of calcium ions from a RyR channel on terminal pond; (4) building a mathematic model of combining calcium ions and magnesium ions with ATP and parvalbumin separately; (5) building a methematic model of cross-bridge power and a mathematic model of combination of the calcium ions and troponin; (6) building a sarcolemma fatigue model and a metabolism fatigue model during the excitation and contraction processes of the fast muscle fibers of the skeletal muscle. The modeling method of the excitation and contraction processes of the fast muscle fibers of the skeletal musc
