Whole body vibration is an interesting new technology.
I'll admit, back in 98 when I heard of it mentioned in a study I wondered how they vibrated the subjects.
Did the biggest grad student just pick them up and shake them around?
Did they sit on a big wash machine?
Anyway, there is a ton of literature showing benefits with short exposures on a vibration platform including big acute increases in flexability, vertical jump, and other variables relevant to athletes. In fact, in Calgary (Sports Centre) vibration platforms are used for many of the elite athlete warm-up protocols.
Further, there is data showing short exposures can lead to pretty large T and GH bursts.
Finally, there is data suggesting that vibration therapy may lead to increased bone mineral density in populations that can't do weight bearing exercise.
