✦ Synopsis

Abstract

Methods are described whereby initial processes of muscular contraction may be investigated in a mammalian preparation, the soleus muscle of the rat. Conditions are chosen so that recovery is avoided. An isometric tetanus is investigated and an energy balance sheet is drawn up. It is found that there is more heat evolved than can be accounted for in terms of measured chemical reaction. This discrepancy is discussed with reference to the similar results that have been obtained using frog muscle.

I n the course of a study on the heat production in mammalian muscle (Cattell and Shorr, '32) it was observed that the delayed heat in oxygen varied in relation to the initial heat, depending upon the type of contraction.

## Abstract The relative oxygen saturation of hemoglobin and the rate of perfusion are important physiological quantities, particularly in organs such as skeletal muscle, in which oxygen delivery and use are tightly coupled. The purpose of this study was to demonstrate the image‐based calculation o
