Figure 5

Linear recruitment-distortion (LRD) model-predicted force responses to sinusoidal length perturbations of increasing frequency in α-MHC (A) and β-MHC (B) fibers at SL 2.0 or 2.2 μm. Model components are shown in panels C-F to illustrate the SL-based effects on XB recruitment or XB distortion dynamics. Low-frequency model components are shown for fibers from α-MHC (C) or β-MHC (D) fibers. High-frequency model components are shown for fibers from α-MHC (E) or β-MHC (F) fibers. Plotted model predictions are determined based on average model fits to each group of chirp data.
