“…Several studies have looked at the effects of WBV on muscle performance. However, the results are not clear and are sometimes contradictory (9,(13)(14)(15)17,21,22,25,35,38,39 AU7 ). The variability in the protocols used by different authors may explain the inconsistency of the results presented in published studies (13).…”

“…An acute bout of WBV using either side-to-side alternating or vertical simultaneous vibrations have shown to increase [13][14][15] or not change [16][17][18] vertical jumping ability, strength and/ or balance. However, a 9.1% reduction in counter movement jump and/or strength has also been reported after exhaustive or prolonged WBV exercise [19].…”

“…The equivocal findings among studies may be due to the characteristics of WBV protocols, such as the training methods, the loading parameters, the body positions, and the mode of vibration. Although the results regarding power, strength and balance seem to be opposing, the vast majority of studies that investigated the acute effects of WBV exercise on flexibility documented significant improvement (by 8.2-16.2%) [16]. Additionally, an acute bout of WBV may: a) increase vasodilatation of vibrating muscles, cutaneous and deep vessel blood flow and muscle temperature, b) increase heart rate and c) reduce tissue viscosity and increase muscle elasticity [20].…”

CommentaryOpen AccessWhole-body vibration (WBV) has received a lot of attention as an effective exercise modality in sports and rehabilitation settings during the last decades [1,2]. Many health centres promoted WBV exercise as an innovative mode of exercise that requires less volitional input and may replace traditional resistance exercise. More specifically, WBV exercise has gained popularity as an alternative less fatiguing and less time-consuming mode of exercise for improving different features of physical fitness and health. WBV has also been marketed, by many companies, as a suitable weight-loss and body toning workout, demonstrating that 10 min of WBV exercise is equal to 1 h of traditional resistance exercise [3]. However, the important question is: 'Ηas WBV exercise the ability to improve various indices of health, overall fitness and functional capacity, as previously purported by the lay literature?' WBV is a mechanical stimulus characterized by oscillatory motion [1]. During WBV exercise, mechanical stimuli are transferred from the feet to the rest of the body by use of vibrating platforms [2,4]. The potential mechanisms that might explain the possible beneficial effects of WBV on neuromuscular performance comprise hormonal factors, the activation of the "tonic vibration reflex", and alterations in proprioceptors discharge [5]. The WBV loading parameters include frequency (the repetition rate of the cycles of oscillation, in Hz), amplitude (the extent of the oscillatory motion, in mm) and duration [1]. The interaction of frequency and amplitude determine the WBV acceleration (in m/s 2 ), and their different combinations determine the training load [6,7].

“…Já é bem conhecido que diferentes frequên-cias de vibração de corpo inteiro (VCI) geram diferentes efeitos sobre o desempenho muscular (Bazett-Jones, Finch, & Dugan, 2008;Bedient et al, 2009;Gerodimos et al, 2010). Este fenómeno pode ser explicado pelo fato de que a combinação da frequência e amplitude de vibração resulta em uma determinada aceleração e, por isso, alterações na frequência geram mudanças na aceleração resultante (Issurin, 2005;Rittweger, 2010;Wilcock, Whatman, Harris, & Keogh, 2009).…”

ARTIGO ORIGINAL | ORIGINAL ARTICLE RESUMOO objetivo do presente estudo foi verificar o efeito crônico do treinamento de força de membros inferiores com diferentes frequências de vibração localizada sobre a corrida de velocidade. Após a realização de um teste de velocidade de corrida de 40m (V40m), 55 homens, não treinados, foram distribuídos em quatro grupos: Isométrico, vibração localizada com frequência de 8-Hz, vibração localizada com frequên-cia de 26-Hz e Controle. Após as 4 semanas de treinamento foi realizado novamente o teste V40m. A comparação das médias dos quatro grupos nas etapas de pré e pós-teste foi realizada a partir da ANOVA com Medidas Repetidas e post hoc de Tukey. Não foram encontradas diferenças significativas entre os valores de velocidade média no teste V40m entre o pré-teste e pós-teste para nenhum dos quatro grupos citados. A partir dos resultados encontrados, foi possível concluir que o treinamento de força com aplicação de vibração localizada na direção da resultante das forças musculares, com frequências de 8 e 26 Hz, não foi capaz de aumentar a velocidade de corrida. Palavras-Chave: Treinamento, Vibração, Velocidade ABSTRACTThe aim of this study was to verify the chronic effect of strength training for lower limbs with different frequencies of local vibrations on the running speed. After performing the test run speed of 40m (V40m), 55 untrained men were distributed into four groups: Isometric, 8-Hz, 26-Hz and Control. After 4 weeks of training, was performed the test V40m. The ANOVA with repeated measures and Tukey's post hoc were used. There were no significant differences between the values of average speed in the test V40m between the pretest and posttest for any groups. From the results, it was concluded that strength training with local vibrations applied in the direction of the resultant muscle forces, with frequencies of 8 and 26 Hz, was not able to increase running speed.
