Abstract

Background. The association of metabolic syndrome (MetS) and obstructive sleep apnea (OSA) impairs sympathovagal balance. However, the mechanisms are not completely understood. Metabolic and inflammatory alterations can be candidates to explain, at least in part, this impairment. Objectives. We will investigate: 1) The overlap of OSA in MetS has an additive effect on metabolic and inflammatory alterations; 2) The association among these alterations and sympathovagal balance; and 3) The effect of hypocaloric diet and exercise training (D+ET) in MetS risk factors, severity of OSA, sympathovagal balance and inflammatory and metabolic markers in patients with MetS. Methods. MetS patients (ATP-III) will be divided into MetS+OSA and MetS-OSA and randomized in to: D+ET (D, a decrease of 500 kcal/day, and ET, 3session/week, 50-70% VO2peak) or control period (no intervention) during 4 months. We will evaluate OSA (polysomnography), functional capacity (cardiopulmonary exercise test), sympathovagal balance (heart rate variability), muscle sympathetic nerve activity (microneurography), insulin resistance (oral glucose/insulin test tolerance and HOMA), leptin and adiponectin levels, TNF-±, protein C-reactive, IL-1B and IL-6. Main Outcomes. 1) Clarify the influence of metabolic and inflammatory alterations over the sympathovagal control; and 2) The effect of D+TF in decreasing risk factors for MetS, severity of OSA, sympathovagal balance, and their possible association with the improvement of metabolic and inflammatory markers, especially in patients with OSA.
