Abstract Summary
The mechanical impedance of active muscle affects the stability of musculoskeletal systems to perturbations. Following a recent experimental finding, we have developed a three filament muscle model in which myosin loads titin when shortening and clutches onto titin during lengthening. A virtual active lengthening experiment indicates that this mechanism can explain the steady increase of force during muscle stretching but that the model is missing terms related to residual force enhancement.
