Abstract
In exercise by a bicycle ergometer, running and exercise of going up and down stairs, I compared the oxygen consumption with the degree of fatigue as measured by the method of electric flicker and obtained the following results.
Data of the electrical measurements went nearly parallel with oxygen consumption during the exercises, while during the time of recovery some discrepancy was found. between both sorts of measurements; the recovery was attained always earlier as to oxygen consumption than as to the electrical values.
The time course of recovery showed sometimes especially after severe exercise a negative phase which could be proved more clearly by the electrical method than by the measurement of oxygen consumption.
