This study evaluated the effects of 6 weeks of whole-body vibration (WBV) exercise on flexibility and the rating of perceived exertion (RPE) in metabolic syndrome (MetS) individuals using 2 biomechanical conditions (fixed frequency [FF] and variable frequency [VF]). Nineteen MetS individuals were randomly allocated in FF-WBV (n = 9, 7 women and 2 men) and VF-WBV (n = 10, 8 women and 2 men) groups. Anterior trunk flexion (ATF) and RPE were determined before and after each session. The acute cumulative exposure effects were analyzed. The FF-WBV group was exposed to 5 Hz on a side alternating vibrating platform (SAVP), exposed to 10 and 50 seconds with the SAVP turned off. The VF-WBV group individuals were intermittently exposed (1 minute WBV exercise/1 minute rest) to 5 to 16 Hz, increased by 1 Hz per session and the peak-to-peak displacement (PPD) were 2.5, 5.0, and 7.5 mm. Regarding to ATF, significant improvements ( P < .05) were observed in the in the acute (VF group) and cumulative intervention (FF and VF-WBV groups). The RPE significantly ( P < .05) improved only in VF-WBV (cumulative intervention). In conclusion, WBV exercise improved the flexibility and decreased the RPE in MetS individuals. These findings suggest that WBV exercise can be incorporated into physical activities for MetS individuals.

Background:Duchenne muscular dystrophy (DMD) is caused by a defective gene located on the X-chromosome, responsible for the production of the dystrophin protein. Complications in the musculoskeletal system have been previously described in DMD patients. Whole body vibration exercise (WBVE) is a treatment that improves musculoskeletal function in movement disorders. The aim of this study was to review the effects of WBVE on functional mobility, bone and muscle in DMD patients.Materials and Methods:Four databases were searched. Three eligible studies were found; all three conclude the management of DMD patients with WBV was clinically well tolerated. The studies used a side-alternating WBV system, frequencies 7 - 24 Hz; and amplitudes 2 - 4 mm.Results:A work indicates that a temporary increase in creatine kinase in DMD during the first days of WBV was observed, but other authors did not find changes. No significant changes in bone mass, muscle strength or bone markers. Some patients reported subjective functional improvement during training. Interpretation:Conclusion:It is concluded that WBV seems to be a feasible and well tolerated exercise modality in DMD patients.

Efeitos dos exercícios de vibração de corpo inteiro na flexibilidade e no nível da dor de mulheres com síndrome metabólica: um estudo piloto A síndrome metabólica (SMet) é caracterizada por um conjunto de fatores de risco, como diabetes e/ou resistência insulínica, obesidade abdominal, dislipidemia, hipertrigliceridemia e pressão arterial elevada, que aumenta o risco cardiovascular do indivíduo. O exercício físico regular promove a redução dos fatores de risco coronariano, bem como dos efeitos deletérios da SMet. Os exercícios de vibração de corpo inteiro (EVCI) executados na plataforma oscilante/vibratória (POV) são uma alternativa de fácil aplicação para a melhora também da força muscular e da qualidade de vida. Objetivo: Avaliar os efeitos cumulativos dos EVCI na flexibilidade e na dor em mulheres com SMet. Material e Métodos: Os efeitos cumulativos do EVCI (seis semanas) sobre a flexibilidade e a dor de dez mulheres, sendo cinco no grupo controle (GC) e cinco no grupo de EVCI (GEVCI), foram avaliados por meio do teste de flexão anterior de tronco (FAT) e do nível de dor pela escala numérica de dor (END). Resultados: Em relação à flexibilidade, os resultados sugerem que no efeito cumulativo houve melhora (p≤0,05) no GEVCI. Considerando o nível de dor, também foi verificado no efeito cumulativo uma redução da dor. Conclusão: Os EVCI seriam capazes de gerar respostas fisiológicas para melhorar a flexibilidade de mulheres com SMet, assim como alterar o nível de dor, no efeito cumulativo.Descritores: Síndrome metabólica; Exercício de vibração decorpo inteiro; Flexibilidade; Dor.
