- Abstract
Obstructive sleep apnea (OSA) is associated with increased cardiovascular morbidity due, in part, to impaired vascular function. Exercise confers cardioprotection by improving vascular health. Yet, whether OSA severity affects the vascular improvements conferred with exercise training is not known. Overweight (body mass index (BMI) >27 kg/m2) adults were evaluated for OSA and enrolled in a 6‐week exercise intervention. Baseline assessments of brachial artery flow‐mediated dilation (BAFMD), central augmentation index (AIx), and pulse wave velocity (PWV) were repeated post‐training. Fifty‐one participants (25 men; 26 women) completed the study. Despite improved aerobic capacity (P =.0005) and total fat mass (P =.0005), no change in vascular function was observed. Participants were divided into two severity groups according to their baseline total apnea‐hypopnea index (AHI) as either 5 to 14.9 events per hour (n = 21; Age = 48 ± 7 years; BMI = 33.7 ± 4.6 kg•m−2) or ≥15 events per hour (n = 30; Age = 56 ± 13 years; BMI = 34.3 ± 4.2 kg•m−2). No effect of OSA group was observed for BAFMD (P =.82), AIx (P =.37) or PWV (P =.44), suggesting that OSA severity does not influence the effect of exercise on vascular function. The vascular effects of extended exercise programs of greater intensity in overweight OSA patients should be examined.
