Abstract
BackgroundThe purpose of this study was to verify the effects of eight weeks of resistance training (RT) on 24 hour blood pressure (BP) in patients with and without metabolic syndrome (MetS).MethodsSeventeen women volunteered to participate in this study, 9 with MetS (37.0 ± 8.7 yrs; body mass 77.3 ± 9.7 kg; body mass index 30.3 ± 4.2 kg · m-2) and 8 without MetS (35.1 ± 7.2 yrs; body mass 61.3 ± 8.1 kg; body mass index 24.2 ± 2.5 kg · m-2). Individuals were subjected to eight weeks (3 times/week) of whole body RT comprised of one exercise for each main muscle group with three sets of 8–12 repetitions of each subject’s maximal load . A rest interval of one minute was allowed between sets and exercises. Twenty-four hour BP was measured by ambulatory blood pressure monitoring.ResultsMean and diastolic night-time BP decreased (−3.9 mmHg, p = 0.04; -5.5 mmHg, p = 0.03, respectively) after eight weeks of training in MetS patients. This decrease was observed at 11:00 pm, 02:00 am (only diastolic), 07:00 am, and 6:00 pm. There was no training effect on BP in women without MetS.ConclusionsConsidering the elevation of BP as a contributor to the pathogenesis of MetS, and also to the increase of cardiovascular risk, this study supports RT as a non-pharmacological therapy in the management of BP control for MetS.
Highlights
The purpose of this study was to verify the effects of eight weeks of resistance training (RT) on 24 hour blood pressure (BP) in patients with and without metabolic syndrome (MetS)
Resting 12-lead electrocardiogram recordings obtained from all subjects before participation in this study showed normal electrocardiographic patterns
To the best of our knowledge, this is the first study to evaluate the effects of eight weeks of RT on 24 h BP in individuals with MetS
Summary
The purpose of this study was to verify the effects of eight weeks of resistance training (RT) on 24 hour blood pressure (BP) in patients with and without metabolic syndrome (MetS). Metabolic syndrome (MetS) is characterized by the grouping of several cardiovascular risk factors such as central obesity, dyslipidemia, insulin resistance, elevated glucose plasma levels and elevated blood pressure (BP) [2]. The decrease of atherogenic dyslipidemia, prothrombotic state and BP is important to reduce the risk for cardiovascular diseases. This reinforces the importance of developing effective and affordable strategies such as exercise programs to prevent and treat cardiovascular risks [5]
