Bad Vibes: Vibration Training is Ineffective!

What's all the Buzzzzzzz about with Vibration training? Really, that is all it is, buzzz, buzzz, buzzz.  Like many types of "fad" training, Vibration training is starting to shake apart.  And the studies are proving it. 

Training on a vibration platform is less effective that weight training alone- according to a study led by Ezio Prestoni from the  University of Bath in the UK.

Vibration involves doing basic exercises, such as squats, push-ups, lunges, and modified pull-ups on a vibrating platform. Vibration is transferred to the feet, hands, and butt, which are in contact with the vibration plate or handlebars. 

Vibration activiates stretch receptors in the muscles, which triggers thousands of small relfex muscle contractors.  Vibration training in ineffective in moderately fit people.

Here's even more evidence... Already in 2009, researchers were already disregarding claims that vibration training would help increase hormonal levels that advertisers for the work out headlined.  Check out this article...

More Evidence to Indicate Whole Body Vibration to be Ineffective

Researchers from the Institute of Sport and Recreation Research, Faculty of Health and Environmental Science and Auckland University of Technology in New Zealand conducted a review of existing research and their findings are published in the March 2009 (Volume 23, Number 2) edition of the National Strength and Conditioning Association’s Journal of Strength and Conditioning Research.
In an earlier article I discussed the researchers’ conclusion that WBV does not enhance speed. However, in a paper titled “Vibration Training: Could it Enhance the Strength, Power or Speed of Athletes?” the researchers found a lack of reliable evidence to support the use of WBV in other areas, as well.
Online access to the journal is provided for NSCA members only.
A common claims made in sales materials and web sites is that WBV training has a positive impact on hormonal levels, specifically that testosterone and human growth hormone (HGH) levels are raised as a result of standing on these vibrating platforms. The authors of this review discuss the results of three studies that have been done to determine the effect WBV has on the endocrine system.
A study conducted by Kvorning et al (“Effects of Vibration and Resistance Training on Neuromuscular and Hormonal Measures”, 2006) combined exercise with vibration to determine if WBV had a positive effect on the endocrine system. Twenty-eight untrained subjects were split into three groups: vibration-only, vibration and body weight squats, and body weight squats only. Testosterone levels increased similarly for the vibration/squat group and the squat-only group and there was no increase seen in the vibration-only group.
These findings are in line with two other studies. DiLoreto et al (“Effects of Whole Body Vibration Exercise on the Endocrine System of Healthy Men,” 2004) saw no increase in testosterone or HGH levels in 10 men who stood on a WBV platform for 25 minutes and Bosco (“Hormonal Responses to Whole Body Vibration in Men,” 2000) observed an increased in HGH and smaller increase in testosterone for subjects who squatted on a vibrating platform.
The findings of these researchers in this review of current and reliable studies stand in stark contrast to the claims made by companies marketing WBV platforms.
With regard to improving an athlete’s strength the authors of this review analyzed five studies; three studies observed strength benefits and two studies found no benefits. The authors of this review found a variety of study design inconsistencies that call into question the positive results.
