Whilst exposure to vibration is traditionally regarded as perilous, recent research has focussed on potential benefits. Here, the physical principles of forced oscillations are discussed in relation to vibration as an exercise modality. Acute physiological responses to isolated tendon and muscle vibration and to whole body vibration exercise are reviewed, as well as the training effects upon the musculature, bone mineral density and posture. Possible applications in sports and medicine are discussed. Evidence suggests that acute vibration exercise seems to elicit a specific warm-up effect, and that vibration training seems to improve muscle power, although the potential benefits over traditional forms of resistive exercise are still unclear. Vibration training also seems to improve balance in sub-populations prone to fall, such as frail elderly people. Moreover, literature suggests that vibration is beneficial to reduce chronic lower back pain and other types of pain. Other future indications are perceivable.

“…and as to whole-body vibration impediment, many investigations about the effects of the spine on a driver are made in Europe and America [1][2][3][4] . On the other hand, there are quite a few studies on the effects of a circulatory organ system, a respiratory-organs system, and a digestive organ system [5][6][7][8][9] . Until now in our country, there is no full-scale investigation for the health disorders among workers who were occupationally exposed to whole-body vibration, there are a few investigations about some of forklift workers and taxi drivers [10][11][12] .…”

Effects of Short-Term Exposure to Whole-Body Vibration on Wakefulness Level

To investigate the relationships between whole-body vibration and changes in wakefulness,We measured the change of a subjective wakefulness level and electroencephalogram (EEG). Subjects are ten healthy male university students. The subjects were exposed to whole-body vibration with frequency (10 Hz) and acceleration level (0.6 ms -2 r.m.s.) for 12 min in the seated position. Subjective wakefulness level was evaluated using the questionnaire of VASS (Visual Analog Sleepiness Scale) and KSS (The Kwansei Gakuin Sleepiness Scale). For the electroencephalogram (EEG) measurement, AAT (Alpha Attenuation Test) which repeats three times each opened and closed eye for 1 min was conducted. Wakefulness levels were defined as the ratio of mean alpha-wave power during eyes closed versus eyes opened. VASS and KSS increased and subjective level of wakefulness decreased from pre-to post exposure in all subjects, regardless of vibration exposure. The objective wakefulness levels of AAT were reduced at the post-exposure test in all subjects. In the case with exposure to whole-body vibration was a significant difference from the case without exposure to whole-body vibration. It is suggested that a short-term exposure to whole-body vibration may cause a reduction of wakefulness level.

“…Di Loreto et al, 2004 andGoto andTakamatsu, 2005 have reported that the plasma concentration of epinephrine and norepinephrine are increased after WBV exercises. Ishitake et al, 1999 have suggested that short-term exposure to WBV can suppress the gastric myoelectric activity as a responses that would be mediated by neurohumoral effects due to the mechanical effect of WBV. It is possible to consider that this neuroendocrine response has been proposed to be the reason for reduced gastric motility during WBV exercise, although direct mechanical influences could also play a role.…”

Vibration is a mechanical stimulus that is characterized by an oscillatory motion. When there is a direct contact of a person, in general standing on the base of this type of platform, the vibration that is produced in these machines is transmitted to the body of the subject producing whole body vibration (WBV) exercises. Biological effects can be associated with the WBV exercises with desirable and undesirable consequences. These effects of the WBV exercises seem to be related to a direct effect in a tissue/organ/system and/or or to indirect effects due to alteration of the plasma concentration of some hormonal and non hormonal biomarkers. The aim of this investigation is to present a revision about hormonal and non hormonal biomarkers in human beings submitted to WBV exercises that have suffered alteration in the plasma concentrations. Searches were performed in the PubMed and Scopus databases with the key words "whole body vibration". Papers were selected following defined criteria. Considering the WBV exercise, hormonal fluctuations of testosterone, growth, insulin-like growth factor1, epinephrine, norepinephrine, cortisol, irisin, parathyroid hormone and sclerotin are observed. Non hormonal biomarkers have suffered alterations in response to WBV, as glucose, free fatty acids, adiponectin, transforming growth factor-beta1, nitric oxide, osteopontin, interleukin-1beta, bonespecific alkaline phosphatase, cartilage oligometric matrix protein and tumor necrosis factor-alpha in plasma concentration. In conclusion, putting together the findings related to the alterations of the concentration of hormonal and non hormonal biomarkers due to the WBV exercises, it is possible that the fluctuations in the plasma concentrations of these biomarkers might help us understand better the biological effects of this kind of exercises, probably due to neuroendrocrine responses.

Abstract: These results suggest that short-term exposure to WBV can suppress the gastric myoelectric activity, the responses on which may be mediating by neurohumoral effects as well as the mechanical effect of WBV.
