Abstract
Objective: The aim of this study was to verify the influence of 6 weeks of whole-body vibration training on the pro- and anti-inflammatory cytokines (IL-2, IL-4, IL-6, IL-10, IFN-ɣ e TNF-α) in young, eutrophic and sedentary women. Methods: Twenty-six participants were randomly divided into two groups: Vibratory Platform Group (GV, n = 13) and Ergometry Group (GE, n = 13). The training program of both groups was of 20 minutes / session, 3 times per week, in non-consecutive days for 6 weeks. The load of the training was adjusted with the adapted Borg scale. GE was submitted to aerobic activity sessions in a cycle ergometer. GV was submitted to vibration platform stimulation sessions. After training program both groups were submitted to 6 weeks of detraining. Results: GV increased levels of IL-4, IL-6, IL-10 and TNF-α after training, and it decreased all of them after detraining phase. GE increased IL2, IL-4, IL-6 and IL-10 only after the detraining period. Conclusion: 6 weeks of whole-body vibration training can promote an increase in pro- and anti-inflammatory cytokines in young, eutrophic and sedentary women, however these effects seem to be transitory as the exercise is discontinued.
Highlights
Whole-body vibration training (WBV) became popular as an alternative training model for traditional resistance training, in is characterized by a vibration stimulus during exercise that is induced by an oscillatory / vibratory platform.the vibration exercise is based on controlled oscillations, where the vibration is transferred from a device to the human body (Martínez-Pardo, Martínez-Ruiz, Alcaraz, & Rubio-Arias, 2015; Martínez-Pardo, Romero-Arenas, Alcaraz, &Research, 2013)
There are many studies that presented some positive effects of WBV, there is a gap regarding the effects of WBV on inflammatory markers and immune system, the limited evidence suggests that an acute WBV session can promote improvements on inflammatory markers of elderly and in individuals with fibromyalgia (Ribeiro et al, 2018; Simão et al, 2012)
For the determination of pro- and anti-inflammatory cytokines such as IL-2, IL-4, IL-6, IL-10, interferon (IFN)-ɣ and tumor necrosis factor (TNF)-α, 5 mL of blood was collected by peripheral venous puncture in EDTA anticoagulant at the rate of 1.0 mg/dL, the samples were centrifuged for 15 min at 5,000 RPM, this serum was stored at - 20° C and processed all at the same time, using the technique of flow cytometry (BD LSRFortessa, São Paulo, Brazil) (Givan, 2011; Nolan & Condello, 2013; Pockley, Foulds, Oughton, Kerkvliet, & Multhoff, 2015), the human analysis kit (BD Biosciense, San Diego, CA, USA) was used; the event counting was adopted with fully automated, high quality standard, for the identification and quantification of the samples
Summary
Whole-body vibration training (WBV) became popular as an alternative training model for traditional resistance training, in is characterized by a vibration stimulus during exercise that is induced by an oscillatory / vibratory platform. There are many studies that presented some positive effects of WBV, there is a gap regarding the effects of WBV on inflammatory markers and immune system, the limited evidence suggests that an acute WBV session can promote improvements on inflammatory markers of elderly and in individuals with fibromyalgia (Ribeiro et al, 2018; Simão et al, 2012) In this sense, Hazell, Olver, Hamilton, Lemon, and Research (2014) evaluated the acute effects of the WBV on inflammatory markers, interleukin (IL)-6 and IL-10, immediately after 4 and 24 hours after the exercise session. We hypothesized that WBV would induce a regulation on the pro- and anti-inflammatory cytokines
