| Research Abstract |
This study revealed that (1) repeated and exaggerated ventilation during exercise produced by short term aerobic training combined with chest wall restriction or inhalation of hypoxic gas, reinforced subsequent ventilatory response to normal exercise, indicating that learning should be involved in the respiratory control during exercise, and that (2) high intensity cycle exercise often induced a locomotor-respiratory coupling and resultant easiness during exercise, while during moderate intensity cycle exercise which was often used in aerobic exercise, there was no difference in cardio-respiratory responses between coupling and non-coupling so that the locomotor-respiratory coupling should have no beneficial effect on moderate intensity exercise. These results suggest that during aerobic exercise, we should keep in mind to breathe slowly rather than to synchronize respiration to locomotion, and that appropriate breathing way during exercise could be obtained from repetitive learning.
