“We have shown that acute exposure to whole-body vibration causes increased plasma concentration of testosterone and growth hormone, and a decreased plasma concentration of cortisol. The increases in neuromuscular effectiveness and testosterone concentration were simultaneous but independent responses, however the two phenomena may have a common mechanism.”

Mechanical Stimulation in the Form of Vibration Prevents Postmenopausal Bone Loss in Ovariectomized Rats

“The rate of remodeling activity is very low in rats, but is activated after ovariectomy, resulting in negative bone balance. Moreover, ovariectomy increases both the length of the long bones by stimulation of longitudinal growth and the inner cross section area (cortex) by stimulation of endosteal bone resorption. These findings were confirmed by our study. The efficacy of agents and exercise regimens in the immediate post-ovariectomy period can be evaluated in terms of their ability to prevent bone loss through inhibition of bone turnover. Thus, it seems that vibration exhibits a suppressant effect on increased bone turnover.”

New insight about the relationship between Bone strength and muscle strength-H.Sliessl-2000
A 6 month study of post menopausal women found that vibration training had a net 1.5% increase in hip bone health compared to regular resistance training. Vibration training was also accomplished in less time than resistance training.

A 12 week study found that strength gains from vibration exercise (maximum of 20 minutes, 3 times per week) were equivalent to one hour of conventional exercise.
