Why the study?
Does electrically induced muscular work differ from normal voluntary work in its effects on cardiac output, blood pressure, and pulse rate?

The regulation of circulation during steady-state muscular work is likely governed by reflex impulses from working muscles rather than cortical impulses.
Animal data implicate peripheral reflexes in circulatory control during work; leaves open translation to human voluntary vs. stimulated exercise.
Summary. In a series of experiments the cardiac output, the blood pressure and the pulse rate have been determined during electrically induced—and normal voluntary Work. The results showed that the circulation was increased corresponding to the oxygen consumption independently of the kind of work performed. From these results it is concluded, that the cortical impulses play no part‐in the regulation of the circulation in the steady state of muscular work. This together with other evidence discussed in this paper makes it probable, that the regulation of the circulation during muscular work is governed by reflex impulses from the working muscles.
