title: The role of shortening and tension in the heatproduction of muscle.
abstract: 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.
