Conditions

The subjects in the present study are healthy humans. We think that respiratory muscle training would be useful for the patients with pulmonary disease and heart failure.

Interventions

We measure respiratory, cardiovascular, and sympathetic nerve responses during voluntary hyperpnoea and exercise. Frequency: 3-6 times/subject, Exercise intensity: 10-70%VO2max, Exercise duration: 10
