As revealed in my first two installments in this series, the quality of research provided by the manufacturers of Whole Body Vibration platforms is lacking. In this latest installment of Debunking the Myth of WBV I’m going to provide a review of items five through nine on the “Researches” (sic) page of the Hypergravity web site.
The fifth item of research is titled Whole body vibration exercise; are vibrations good for you? Clicking on the link takes you to the Pubmed website where you can read a summary paragraph for a review of research that deals with the efficacy of WBV training.
This discussion touches on many of the different effects that WBV is alleged to provide.
The authors of this review - Cardinale and Wakeling - make the following statement in the section titled Chronic Effects Of Vibration On Neuromuscular Performance, “If well trained populations use vibration exercise with the aim of improving neuromuscular performance, an optimal amplitude and frequency should be coupled with an optimal level of muscle activity on which the vibration stimulation can be superimposed. Of course, this should be the aim of future studies and for this reason we have recently patented an exercise device able to allow the user to perform vibration exercise while controlling the level of force and muscle mechanics (Patent Number WO2004009173).”
The authors’ have nothing more than this theory that an optimal amplitude and frequency may make WBV suitable for trained members of the population, and as a result of this theory these researchers have patented their own vibrating platform. This research can hardly be considered objective since the authors of this review have a vested interest in providing us with data that supports their theory.
The design of the researchers patented exercise device isn't based on facts culled from research, but in a unproven theory which makes this whole exercise suspect.
This same section starts off with the statement; “Chronic studies seem to provide more supportive evidence for the possibility of using WBVT effectively in different populations. A few weeks of training seem to produce conflicting results.” This is wishy-washy double talk that the authors use because they do not want to say that there is no evidence that WBV provides any real benefits.
