Expiratory Muscle Strength Training Reduces Oxidative Stress and Systemic Inflammation in Men with Obstructive Sleep Apnea Syndrome: A Double-Blinded, Randomized Parallel Trial

This study aimed to evaluate and compare the effects of high and low-intensity expiratory muscle strength training (EMST) on disease severity, systemic inflammation, oxidative stress, respiratory muscle strength, exercise capacity, symptoms, daytime sleepiness, fatigue severity, and sleep quality in male patients with obstructive sleep apnea syndrome (OSAS).
