A continuum-mechanical skeletal muscle model including actin-titin interaction predicts stable contractions on the descending limb of the force-length relation
Fig 11
Histogram of half-sarcomere lengths in model with distributed material properties after an active stretch from L/L0 = 1.05 to 1.25 (red) and after a fixed-length contraction at the same final length L/L0 = 1.25 (blue).
This figure compares steady-state results, i. e. transient effects of the force-velocity relation have disappeared. Left: Variable passive properties, right: Variable active properties.
