| Outline of Final Research Achievements |
In this study, we attempted to clarify the effects of respiratory muscle activation on cardiovascular regulation. Study 1: Significant increases in arterial blood pressure and sympathetic vasomotor outflow appeared during exercise with expiratory resistance. Study 2: The increase in arterial blood pressure (ABP) during hyperpnoea was lower in young men compared to men. Study 3: During leg cycling with inspiratory resistive breathing, sympathetic vasomotor outflow was increased, accompanied by an increase in ABP. Young women, compared with age-matched men, had less of an increase in ABP. These results suggest that the attenuated inspiratory muscle-induced metaboreflex during exercise in young women could be attributed, in part, to a lesser sympathetic vasomotor outflow.
