Shortening velocities were measured for in vitro rat left ventricular trabeculae carneae preparations stimulated to contract isotonically with different loads, and at temperatures from 20 C to 35 C. The data obtained were used to derive the heat of shortening constant, a, the velocity constant, b, and the maximum isometric tetanic tension term, P0, of the characteristic force-velocity equation. The study showed that the derived constants a and P0 statistically did not vary with temperature, but that the velocity constant b increased linearly as temperature increased. Differences between cardiac and skeletal muscle are discussed.
