Whole-body vibration improves the functional parameters of individuals with metabolic syndrome: an exploratory study

Abstract

BackgroundMetabolic syndrome (MetS) is a cluster of metabolic abnormalities that increases the cardiovascular risk. Regular physical exercise can promote benefits, but the MetS individuals are demotivated to perform it. Thus, new possibilities are important as an alternative intervention. The whole-body vibration can be considered an exercise modality and would be a safe and low-cost strategy to improve functional parameters of individuals in different clinical conditions. The aim of this exploratory study was to assess effects of whole-body vibration on functional parameters of MetS individuals. The hypothesis of this work was that the whole-body vibration could improve the functionality of MetS individuals.MethodsTwenty-two individuals performed the intervention. The vibration frequency varied from 5 to 14 Hz and the peak-to-peak displacements, from 2.5 to 7.5 mm. Each session consisted of one minute-bout of working time followed by a one minute-bout of passive rest in each peak-to-peak displacement for three-times. The whole-body vibration protocol was applied twice per week for 5 weeks. Data from the trunk flexion, gait speed, sit-to-stand test and handgrip strength were collected. Physiological parameters (blood pressure and heart rate) were also evaluated. The Wilcoxon Rank test and Student t-test were used.ResultsNo significant changes (p > 0.05) were observed in physiological parameters (arterial blood pressure and heart rate). Significant improvements were found in trunk flexion (p = 0.01), gait speed (p = 0.02), sit-to-stand test (p = 0.005) and handgrip strength (p = 0.04) after the whole-body vibration.ConclusionsIn conclusion, whole-body vibration may induce biological responses that improve functional parameters in participants with MetS without interfering in physiological parameters, comparing before and after a 5-week whole-body vibration protocol.Trial registrationRegister in the Registro Brasileiro de Ensaios Clínicos (ReBEC) with the number RBR 2bghmh (June 6th, 2016) and UTN: U1111–1181-1177.

Respiratory Muscle Training Improves Functional Outcomes and Reduces Fatigue in Patients with Myasthenia Gravis: A Single-Center Hospital-Based Prospective Study

“…All participants have signed an informed consent form, and the study was conducted in accordance with the Declaration of Helsinki and approved by the hospital's Institutional Review Committees on Human Research (IRB 105-5274C). The Transparent Reporting of Evaluations with Nonrandomized Designs (TREND) statements were used to report all the different steps of the interventions utilized in this study [12,13].…”

Whole-Body Vibration Exercise as an Intervention to Improve Musculoskeletal Performance

“…These findings can contribute to decrease the possibility of injury, as in the sports, in the improvement of the fitness and on the management of various diseases. WBV exercise can produce beneficial responses, including improvements in muscle strength in trained (athletes) and untrained individuals and in patients with several clinical conditions, such as, chronic obstructive pulmonary disease (COPD), Parkinson's disease (PD), metabolic syndrome (MetS), fibromyalgia (FM) and multiple sclerosis (MS) [11][12][13][14][15]. Moreover, improvements in the walking function, the bone mineral density (BMD) in elderly, the low back pain (LBP), health-related quality of life (QOL), fall risk, balance and gait have been described [1,7,[16][17][18][19][20].…”

“…Huang et al [22] studied the influence of WBV intervention frequency, amplitude, and body posture on lower limb muscle activation among people with CS. It was also evaluated whether the EMG response to vibration stimulus differed between paretic and non-paretic Sá-Caputo et al [13] assessed effects of WBV exercise on functional parameters of MetS individuals. The biomechanical parameters of the mechanical vibration were frequency (from 5 up to 14 Hz) and the peak-to-peak displacements (from 2.5 up to 7.5 mm).…”

Effects of Whole-Body Vibration Exercises on Parameters Related to the Sleep Quality in Metabolic Syndrome Individuals: A Clinical Trial Study

“…In this case, it is relevant to consider the whole-body vibration (WBV) exercise, a modality of PE, an option. WBV exercise has been used as a clinical intervention in individuals with different clinical disorders, including MetS [21][22][23][24][25][26] and it can be considered a feasible, safe, and low-cost technique [27].…”

“…It produces a mechanical vibration (MV) that is transmitted to the body inducing muscle contractions, with physiological responses like those produced by other types of PE, such as aerobic conditioning and strength training [28][29][30]. Biomechanical parameters, such as the frequency (f ) and the peak-to-peak displacement (PPD) of the MV must be considered in the WBV exercise protocols [26,31,32].…”
