Minute-Ventilation Variability during Cardiopulmonary Exercise Testis Higher in Sedentary Men Than in Athletes

摘要

BackgroundThe occurrence of minute-ventilation oscillations during exercise, named periodic breathing, exhibits important prognostic information in heart failure. Considering that exercise training could influence the fluctuation of ventilatory components during exercise, we hypothesized that ventilatory variability during exercise would be greater in sedentary men than athletes.
