Summary
The “steady state” of exercise is only relatively steady; considerable fluctuation in the rate of oxygen consumption occurs from minute to minute. The standard deviations expressed in per cent of mean O2 consumption are smallest with a moderate work load which requires a certain effort and concentration of the subject; they are greater at either extreme of work load. The instability of the “steady state” of exercise appears to be a normal phenomenon.
