The role of shortening and tension in the heatproduction of muscle.
The dependence of the heatproduction of muscle on shortening was examined. An inverse relation was found between heatproduction and shortening as well as tension and shortening, while there was a close positive correlation between heatproduction and tension. The results emphasize the primary importance of tension as compared in the heat production of muscle, to shortening.
