Abstract
Subjects: The subjects for this experiment were 3 cases of Degree I patients, 7 cases of Degree II and 3 cases of Degree III.
Method of Experiment: The subjects were requested to step up and down a platform of 30 cm high at a rate of 18 times per minute. The expired air was taken into the Douglas bags once before and even during the exertion and 3 times after the exertion. The samples of air were analysed by means of Haldane's apparatus. The pulse rates were also taken on those occasions. The rates of energy metabolism (ER) were determined by the following formula in order to omit personal factors.
ER=O2 intake during exertion-O2 intake in repose/O2 intake in basal metabolism
Results of Experiment: 1) The rates of energy metabolism (ER) in the mild cases may, in general, rapidly increase with the initiation of the exertion and decrease suddenly with the termination of the exertion. However, severe cases show low rates of energy metabolism during the exertion, but show high rates after the exertion on the contrary with delayed recovery. 2) The rate of fluctuation in the pulse rate may progress similarly to that of the rate of energy metabolism.
