简要总结
Objective: analyze the effects of isometric handgrip exercise on arterial pressure and on the autonomic cardiac modulation of hypertensive individuals treated in the Unified Health System (UHS).
Intervention: Patients were randomized into Supervised group (SG) and control group (CG). SG will perform supervised isometric handgrip exercise for three weekly sessions in four sets with two minutes of isometric contraction with 30% of maximal voluntary contraction (MVC), In CG, individuals will be encouraged to increase their level of physical activity.
Measurements: Blood pressure, autonomic modulation
详细描述
The objective of this study is to analyze the effects of isometric handgrip exercise on arterial pressure and on the autonomic cardiac modulation of hypertensive individuals treated in the Unified Health System (UHS). Two prospective, randomized, controlled trials will be conducted with hypertensive patients in the public health network of Petrolina (PE) and São Paulo (SP). Included in the study will be individuals with an age group over 18 years of both genders, with systemic arterial hypertension (SAH) controlled with the use of antihypertensive medication, non-smokers and without the presence of diabetes or other cardiovascular diseases that will be allocated randomly in two groups: supervised group (SG) and control group (CG). SG will be instructed to perform supervised isometric handgrip exercise for three weekly sessions in four sets with two minutes of isometric contraction with 30% of maximal voluntary contraction (MVC) of the subjects and interval between two-minute series. In CG, individuals will be encouraged to increase their level of physical activity. Prior to initiation and after 12 weeks of intervention, blood pressure, autonomic cardiac modulation and level of physical activity will be obtained.

- •Those individuals who: a) are diagnosed of diseases such as dyslipidemia, diabetes mellitus, cardiovascular or pulmonary diseases; B) adhere to another program of physical activities besides the training offered by the present study; C) change the class and dose of medication during the study; and d) aggravate the disease.
研究组 & 干预措施
Intervention Group
Subjects will perform three weekly sessions of isometric handgrip training consisting of four series (two in each arm) with two minutes of isometric contraction with intensity of 30% of maximum voluntary contraction with interval between the two-minute series under the guidance of the trained researcher.
干预措施: Intervention Group (Behavioral)
Control Group
Individuals randomized to Control Group will be encouraged to increase their level of general physical activity, but without specific recommendations on physical activity.
结局指标
主要结局
Blood Pressure measure
时间窗: 12 weeks
The subjects will remain for ten minutes in the seated position, following the guidelines of the VII Brazilian Direction of Hypertension. Three consecutive measurements, one minute apart, in the non-dominant arm and with a cuff size suitable for the circumference of the arm will be performed. The value used will be the average of the last two measures, as recommended by the VII Brazilian Arterial Hypertension Guideline.
次要结局
- Heart rate variability measure(12 weeks)
