A comparison of the respiratory responses of jogging in place, an alternative exercise test we recently proposed, was made with those of the Bruce exercise test. We obtained on‐line measurements of heart rate, ventilation, oxygen uptake, and carbon dioxide production from 9 healthy subjects of mean age 25 years. There was a higher heart rate and ventilatory response with jogging than with the Bruce test, but by 10 minutes the responses of the two tests were similar. Oxygen consumption, while higher with jogging, rose in parallel with that of the Bruce test from the second to the seventh min, and the change of the ration of minute ventilation to oxygen consumption indicated that the anaerobic threshold occurred earlier during jogging. These results swhow that jogging in place is more vigorous than the graded exercise test and may produce ischemia earlier.
