O efeito dos exercícios de vibração de corpo inteiro sobre na flexibilidade e no nível de percepção subjetiva de esforço em indivíduos com síndrome metabólica: elaboração de um protocolo

Abstract

Metabolic syndrome (MetS) is a severe clinical disorder, and its management is a challenge for professionals involved in public health. Elderly individuals with MetS have less flexibility and elevated difficulty in performing daily activities compared to those without the disease. Whole body vibration exercises (WBVE) performed on the vibrating platform can reduce the risk of falls in elderly and increase muscle strength, cardiorespiratory function and flexibility in adults. Objective: The aim of this study was to evaluate the effects (acute and cumulative) of WBVE on flexibility and on the level of rating perceived exertion in individuals with MetS, in the period of 6 weeks. Material and Methods: This study recruited 31 subjects and 19 underwent the protocol (58.79 ± 12.55 years, 1.62 ± 0.09 m, height, 86.27 and ± 15.03 kg of body mass). The individuals were randomized into two groups: Sham of 09 and WBVE of 10 individuals. Anterior trunk flexion (ATF) and rating perceived exertion scale (RPE) were determined before and after each session for six weeks. Results: Significant improvements (p≤0.05) of ATF were observed in all interventions (Sham and WBVE groups) in the acute and cumulative effects. There was no reduction in the evaluation of RPE in the acute effect (p>0.05), but a significant decrease (p≤0.05) was demonstrated in the cumulative effect. Conclusion: WBVE would promote physiological effects, which allow the incorporation of WBVE into the physical exercise routine for individuals with SMet with the aim of improving the trunk flexibility and reducing the effort to carry out activities. This favored the elaboration of a clinical protocol.
