| Research Abstract |
In the living body, the regulation of breathing functions in accordance with the metabolic demand of active muscles. However, the ventilatory response at the onset of exercise rapidly increases even when there are still few demands for oxygen in the active muscle. In this study, we examined the physiological implications of this. The response speed of oxygen uptake was faster when we increased 20-second breathing immediately after the start of exercise. On the other hand, the oxygen uptake response speed slowed when we reduced 20-second breathing just after the start of exercise. These results suggest that the initial rapid increase of breathing at the onset of exercise has physiological implications that hasten oxygen uptake in response to exercise.
