Isometric Hand Grip Training in Obstructive Sleep Apnea (OSA)

Effect of Isometric Hand Grip Training on Blood Pressure of Hypertensive Patients With Obstructive Sleep Apnea

Obstructive sleep apnea (OSA) is a common clinical condition, involving the development of arterial hypertension. A Meta analysis study have shown that isometric hand grip training promotes blood pressure reduction. It is going to be conducted a clinical trail to determine the effects of hand grip training in OSA patients to change the arterial hypertension.

Background: obstructive sleep apnea (OSA) is a common clinical condition, involving the development of arterial hypertension. Meta analysis study have shown that isometric hand grip strength promotes blood pressure reduction, and its reduction is higher than that observed after aerobic training. Objective: to analyze the effects of the isometric hand grip on blood pressure changes of patients with uncontrolled arterial hypertension with OSA. Methods: a randomized controlled trial involving 18 adults with OSA and uncontrolled arterial hypertension of both sexes, randomized between control group (receive general guidelines) and hand grip group. 12 weeks of training with load equivalent to 30% of maximum voluntary capacity was performed. All participants will be submitted for evaluation of blood pressure (BP) central and brachial, pulse wave velocity, full polysomnography,before and after the study protocol (the change from the baseline at 12 weeks). Expected results: the authors believe that hand grip training can change (reduce) blood pressure in patient with OSA.

Inclusion Criteria:

• Apnea-Hypopnea Index (AHI) > 5,
• arterial hypertension (systolic arterial pressure > 140 mmHg or diastolic arterial pressure > 90 mmHg)

Exclusion Criteria:

• other heart disease
