Avaliação do efeito dos exercícios de vibração de corpo inteiro na qualidade de vida de indivíduos com síndrome metabólica através do questionário WHOQOL-BREF

Abstract

The metabolic syndrome (MetS) is characterized by cardiovascular risk factors, such as abdominal obesity, arterial hypertension, insulin resistance, intolerance to diabetes/type 2 diabetes and dyslipidemia. People with MetS may also have the quality of life (QoL) compromised and physical exercise can aid these patients. Whole Body Vibration Exercises (WBVE) can be considered as a form of physical exercise and has improved the QoL of different populations. Questionnaires are used to evaluate different conditions of individuals, including QoL. (WHOQOL-BREF) is recommended by the World Health Organization. The hypothesis is that WBVE can improve the QoL of individuals with MetS. The objective of this study was to evaluate the QoL of individuals with MetS who underwent WBVE through of the WHOQOL-BREF questionnaire. The individuals were included in this study after the diagnosis of MetS, according to the Internation Diabetes Federation (IDF), by a team of the Departmento de Clínica Médica, Hospital Universitário Pedro Ernesto/UERJ and of the Programa de Saúde da Família (PSF), Mesquita, Rio de Janeiro, Brazil. They were randomly divided into three groups: (i) control group (CG), (ii) treated with WBVE once a week (WBVE1) and (iii) treated with WBVE twice a week (WBVE2). In the first session, the individual sat in a chair in front of the alternating oscillating/vibratory platform with the feet on its base in 3 different positions, corresponding to peak-to-peak displacements of 2.5, 5.0 and 7.5 mm. From the second to the tenth session, the individual stood on the base of the platform, with his knees flexed at 130º, performing the same positioning described above for the feet. The frequency used in the first session was 5 Hz. From the second to the tenth session was added 1 Hz per session, using 14 Hz in the tenth session. The control group followed the same protocol, but with the platform switched off. The WHOQOL-BREF was completed by the participant and considered to be analyzed before the first and after the tenth session. The Cronbach coefficients were determined for each WHOQOL-BREF domain and the Wilcoxon test (p <0.05) was used. The individuals of the CG did not present statistical difference. The individuals of the WBVE1 group presented improvements on the physical, psychological and environmental domains. The individuals of the WBVE2 group presented improvements on the physical and social relations domains of the WHOQOL-BREF. In this way, it can be concluded that with the use of the WBVE protocol, performed in this study, there was an improvement in the QoL of the individuals with MetS evaluated.
