Energy expenditure, work output and efficiency as functions of relative afterload. (A) Change of enthalpy (squares) and heat (circles), (C) work output, (E) mechanical efficiency and (G) crossbridge (‘XB’) efficiency as functions of relative afterload for a representative trabecula. The corresponding average relations for the Control (thin lines) and STZ (thick lines) trabeculae are shown in B, D, F and H, respectively. The left and the right vertical dotted lines indicate, respectively, the relative afterloads for peak mechanical efficiency and for peak work.
