Pulmonary Training May Alter Exertional Dyspnea and Fatigue Via an Exercise-Like Training Effect of a Lowered Heart Rate
Recent small studies utilizing respiratory muscle training have incorporated a voluntary hyperventilation maneuver via an open chamber gas mixing system (to maintain isocapnic conditions). These studies suggest that the time to exercise exhaustion may be increased at exercise levels near but above the so-called anaerobic threshold after several weeks of intense pulmonary training (1,2).
