Extent of shortening, shortening velocity and shortening power as functions of relative active afterload. (A and B) Maximal extent of shortening (calculated from the end-systolic length in Figure 7C), (C and D) maximal velocity of shortening (at the times indicated by the circles in Figure 7B), and (E and F) maximal power of shortening (calculated as the product of velocity of shortening and active afterload) as functions of relative active afterload for a representative trabecula (left panels) and the average relations (right panels) for the Control (thin lines) and STZ (thick lines) trabeculae.
