The effects of positive airway pressure on cardiovascular responses, perceived effort and time to exhaustion during high-intensity exercise in healthy subjects.
We investigated the effects of continuous positive airway pressure (CPAP) on the time to fatigue, rates of perceived exertion (RPE), and cardiovascular responses during sustained, high-intensity exercise (80% of VO2peak). ⋯ During sustained, high-intensity exercise (80% of VO2peak), CPAP extended the time to fatigue in healthy subjects but did not change the heart rate, blood pressure or rate pressure product. Additionally, the central and peripheral RPEs remained lower for a longer period of time during exercise with CPAP.
