Evaluation of Clinical, Metabolic, and Physical-functional Effects of Systemic Vibratory Therapy in Metabolic Syndrome

Summary

Studies have demonstrated a strong relationship between physical inactivity and the presence of cardiovascular risk factors such as hypertension, insulin resistance, diabetes, dyslipidemia, obesity, and metabolic syndrome. On the other hand, regular physical exercise has been recommended to prevent and treat cardiovascular diseases, their risk factors, and other chronic conditions. Systemic vibration therapy (SVT) has been proposed as an alternative exercise modality for this population.

This project aimed to assess clinical, metabolic, physical, functional, biochemical parameters, quality of life, and sleep quality in individuals with metabolic syndrome undergoing whole-body vibration exercises on a vibratory platform.

This study aimed to evaluate clinical, metabolic, physical-functional, biochemical parameters, quality of life, and sleep quality in individuals with MSy undergoing whole-body vibration exercises. Assessments were conducted before and after the intervention and included cardiovascular responses, dyspnea, fatigue, anthropometric measurements (neck, abdominal, hip, arm, and ankle circumferences), body composition, anterior trunk and lumbar spine flexibility, and laboratory analyses (complete blood count, cholesterol profile, triglycerides, creatinine, uric acid, cortisol, glucose, insulin, growth hormone, vitamin D, and other biomarkers). Questionnaires assessed quality of life and sleep. Neuromuscular function, handgrip strength, lower limb isometric dynamometry, joint goniometry, and functional tests were evaluated.

Participants were randomized into two SVT protocol groups: Fixed Frequency (FF) and Variable Frequency (VF). Both protocols were conducted on a vibratory platform with alternating base displacement.

In the FF group, a frequency of 5 Hz was applied, with peak-to-peak displacements of 2.5, 5.0, and 7.5 mm, a work time of 1 minute (10s "on" and 50s "off"), and 1 minute of rest in an upright position. In the VF group, frequencies varied from 5 to 16 Hz (increasing by 1 Hz per session), with a work time of 1 minute and 1 minute of rest, while peak-to-peak displacements remained the same as in the FF protocol. The protocols were performed in static and dynamic squat positions, twice a week, over six weeks, totaling 12 sessions.

It is expected that this vibratory platform intervention can improve clinical, physical, biochemical, and functional parameters, as well as quality of life and sleep quality in individuals with MSy.

Interventions

DEVICE

Systemic vibratory therapy

The interventions were performed on a vibratory platform with side-alternating displacement of the base (Novaplate Fitness Evolution model, DAF Produtos Hospitalares Ltda, São Paulo). The individual was positioned barefoot, with knees flexed at 130º on the base of the vibratory platform. The protocol was performed over a 6-week period with 2 weekly sessions, totaling 12 sessions. The frequency was 5-16Hz according the protocol, and the peak-to-peak displacement was 2.5, 5.0, and 7.5 mm in all sessions. During the protocol, the individuals performed static and dynamic squats, with one static and one dynamic session (interleaved). The variables were evaluated before and after the interventions.
