A continuum-mechanical skeletal muscle model including actin-titin interaction predicts stable contractions on the descending limb of the force-length relation

Fig 6

Isometric active force—length relations of the different models.

Models and M_ATI reproduce the force—length relation as proposed in [1] that is included at the half-sarcomere level of all models. Models M^Fv and predict different forces on the descending limb. Under steady-state conditions (after 2.5 s) the results of models M^Fv and , as well as those of models and M_ATI, coincide.
