Axial and Radial Forces of Cross-Bridges Depend on Lattice Spacing
Figure 6
Changes in step size with lattice spacing.
Step size varies as lattice spacing diverges from its rest value. Step size is defined as the change in the rest axial offset between the pre- and post-power stroke states. The step size of the 4sXB model and 2sXB model produce different absolute step sizes as lattice spacing change. However, both models exhibit a local maximum step size at a specific lattice spacing with a decreasing step size as lattice spacing diverges from that point.
