Actual (reported)This study evaluated the use of nocturnal continuous positive airway pressure (CPAP) as a potential recovery strategy in healthy male endurance runners without obstructive sleep apnea. Participants completed periods of high-intensity/high-volume and low-intensity/low-volume physical training, first without CPAP and subsequently with nocturnal CPAP. Sleep, physiological, biochemical, psychological, and recovery-related measures were assessed during the study. Polysomnography, blood tests, questionnaires, actigraphy, sleep diaries, and heart rate monitoring were used to evaluate participants across the experimental periods. The objective was to investigate whether nocturnal CPAP was associated with changes in recovery-related measures during different physical training loads.

Actual (reported)REM Sleep Latency
REM sleep latency was measured by overnight polysomnography at baseline and after each five-day training period, including high-intensity/high-volume and low-intensity/low-volume training conditions without and with nocturnal CPAP. REM sleep latency was measured in minutes.

Participants completed a fixed-sequence training protocol consisting of high-intensity/high-volume and low-intensity/low-volume training periods. The training periods were first completed without nocturnal CPAP and subsequently repeated with nocturnal CPAP.
Participants used continuous positive airway pressure (CPAP) during sleep for five consecutive nights during each CPAP training condition.
Participants completed five days of high-intensity/high-volume training followed by a two-day period without training and five days of low-intensity/low-volume training. This training sequence was completed first without nocturnal CPAP and subsequently with nocturnal CPAP.
