Well I would like to start out with a little industry news.......

A certain global retail company of Vibration platforms that has a culture of unethical behavior towards not only the consumer, but the industry itself, appears to be in real trouble. This community has been gunning for them and done everything in our power to effect it's downfall since 2004. That combined with short sighted business decisions has led to the following situation. It has been reported to me that................

(a) ALL their staff globally except 2 people have been "let go" for financial reasons..................

(b) They are rising prices 15% in the hopes of turning a profit..................

(c) The CEO has been told if the financial issues are not sorted in 4 months, the factory gets closed.................

If this is true, and it is the end of this company in its present form, It will signify the beginning of a new chapter for our industry, where we can finally get the real players a chance to shine instead of the marketing pretenders. There are also going to be allot of red faces from those who supported this company and their unethical, dishonest, "get a sale at ANY cost" ways.

Hi all. My Wife Deb and I (Dan) have been running a studio in Canada just North of Calgary, Alberta for a couple of years now. We had taken on quite a challenge with the studio and have developed a passion for what we do. We as well are very excited and proud to be involved in this industry and with the contributing members of this community who have proven to be extremely helpful and knowledgeable yet humble enough to admit learning is a constant for everyone as new studies & technology become available. "We strive to assist those we can and refer to those who can when we are unable."

Hi, I’m Di Heap. On my first visit to Vibra-Train Lloyd Shaw enthused me with a passion for Vibration Training, not only for myself but for everyone. So from my journey as a first time customer to now being an Instructor working for Vibra-Train, I'm really excited about this industry. I have learnt a lot along the way and am able to give advice and answer questions, but I do not “suffer fools gladly” so will be very direct if I think it is necessary.

Hello. My name is John Weatherly. I am trained in sports/exercise science and have consulted/been involved with companies in the vibration industry. I look forward to open and honest discussions on this forum


On The Take With Power Plate? Part 1, by John Weatherly

Editor’s Note:  John T. Weatherly has helped with conditioning programs and research at the U.S. Olympic Training Center in Colorado Springs. John is also a frequent commenter, and now contributor, on the Russells’ Blog. Today’s topic is vibration plates. These plates vibrate like a truck on a highway, supposedly making you fitter. See the video below. Weatherly exposes the unreliable studies that NSCA and others have published on vibration platforms.



On The Take With Power Plate?  Part 1

The idea of using a certain dose of vibration in therapy for various conditions has been around a long time. In 2003, the American College of Sports Medicine (ACSM) published a review article by Cardinale and Bosco covering the use of vibration as an exercise modality (2).   Vibration is thought to work similar to plyometrics. For example see this video.

For detailed potential mechanisms see Cardinale and Bosco (2) or Donaldson and Ross (4). While vibration can be delivered to the body in various ways (i.e., superimposed on a pulley cable), the review by Drs. Cardinale and Bosco seemed to spur research and commercial interest in the use of vibration platforms or plates. This has been termed whole body vibration (WBV). Scores of WBV studies have been published since 2003. Additionally, WBV platforms are now found in commercial, athletic, rehabilitation, and even military settings (i.e., see But, what does this WBV research actually say?

To answer the above question, we need to understand there are different types and brands of WBV platforms (4,8). Some move side to side like a teeter-totter (i.e., Galileo), others vertically (i.e., Nemes or the original steel Power Plate), and are even advertised as being tri-planar now (i.e., newer and lighter weight Power Plate). The material the platforms are made of can vary considerably from steel (original Power Plate) to plastic. Regardless of the type or brand, WBV platforms move a certain distance up and down (amplitude) and at a certain frequency or speed. Amplitude is measured in millimeters (mm) while frequency is measured in Hertz (Hz) (8).

WBV Research

Imagine you were a researcher doing a study on a WBV platform. Your untrained subjects range in body weight from 110 to 300 lbs. You are going to train the subjects three times a week for 8 weeks on this WBV platform at a frequency of 40 Hz and 2 mm amplitude. The results of the WBV group will be compared to a sedentary control group at the end of the study. The manufacturer of the WBV platform you are using tells you the platform is accurate for a wide range of loads but you have not seen any independent testing of this particular brand and model of WBV platform in your review of the WBV literature. This seems odd to you as there is information on other devices used to track movements (i.e., 10). See “Validity and reliability of GPS for measuring instantaneous velocity during acceleration, deceleration, and constant motion.”

Are you, as a research scientist, going to do a pilot study and test the WBV platform yourself? Or, perhaps you could have independent engineering tests done on the platform to make sure it works as advertised for a wide range of loads? That would take a lot of time and possibly money to do this though. If you don’t do either of these and there’s no information in the scientific literature about this particular brand and model of platform, you really won’t know if all the subjects in your study are exercising on the WBV platform at a frequency of 40 Hz and amplitude of 2mm. Those WBV platform people sure seem nice. Heck, they may have given you the platform and funds to do the study in the first place. What are you, as a research scientist, going to do?

Reliability and Validity

Any university researcher knows what reliability and validity mean. Reliability, in our example, is the consistency of the WBV platform(s). Imagine stepping on your bathroom scale and weighing 200 lbs only to find out your weight on the same scale is 100 lbs the next day (not reliable!). Validity is simply measuring what we intend to measure. Whenever a device such as a WBV platform is used to collect data we need to be sure the WBV platform performs as it is supposed to so we are measuring what we want to measure. Otherwise, the data collection methods are erroneous and the data analyzed will be invalid.

Research Papers – The Methods Section

So, how do we know if WBV researchers did pilot studies themselves or had independent engineering tests done on the WBV platforms used in their studies? They should state this in the methods section of their peer reviewed journal articles. If other researchers have tested the exact same brand and model of platform and found it reliable and valid, that should be cited. Research papers have four main sections: introduction, methods, results, and discussion. If the methods section does not explain procedures clearly (such as testing WBV platforms under different loads), then the study can’t be replicated and confirmed by other researchers. The data is invalid if nobody tested the WBV platforms under various loads because nobody would know if the data obtained was reliable and valid (just trusting what the manufacturer said).

Studies on Power Plate’s Own Site

I downloaded and read the methods section for all 41 studies on Power Plate’s site. I didn’t see ANY that reported pilot testing or having independent engineering tests performed on the Power Plate WBV platforms used in their studies.

Out of the 41 studies on Power Plate’s own site, I found Roelants (8) et al. and Delecluse (3) et al. measured accelerations of the platform with an accelerometer. Interestingly, these two studies were published in 2004 and 2003. They appear to have been conducted on the older steel Power Plate platforms and not the plastic or light weight models Power Plate has marketed recently. See, “Amplitude is Everything.”

Lowell et al. stated the portable platform used in their study had a limited amplitude (5). Marin et al. reported measurements with a 70 kg load on the platform (6). This Marin et al.(6) study is the only one I found on Power Plate’s site that even mentioned a measurement with a load prior to doing a study. I wonder why Marin et al. (6) chose a 70 kg load instead of 100 kg or other heavier load?

One group of researchers (1, p.238) states:

“A key reason for inconsistencies in scientific data regarding the effects of WBV may be that protocols vary from study to study. Different frequencies and amplitudes have been applied to different populations with varying recovery periods. Each of these parameters has the potential to impart biological response to vibration training and, therefore, the effects of vibration training on strength and power performance.”

Ironically, Adams et al. (1) didn’t mention the platforms themselves. This is peculiar.

How bad has the WBV Research Been?

The WBV research has been so bad that the International Society of Musculoskeletal and Neuronal Interactions had to publish a paper in 2010 on how to conduct WBV studies. Rauch et al. (7, p.193) state:

“A scientific study can lead to scientific progress only if the resulting study report can be understood by others. This requires a common language and consistent use of well-defined terminology. It is also critical that the methodologies of the study is described accurately and with sufficient detail for others to replicate the study.”

It’s shocking to think of all the invalid studies that have contaminated the WBV literature. Here are actual quotes of Power Plate researcher David Bazett-Jones, provided by Vibra-Train’s Lloyd Shaw:

As far as having engineering reports done on the machines, I would argue that it is the ethical responsibility of the manufacturer to do the testing and report the results. The blame is not on the researchers but the manufacturers.

As far as my (Power Plate) study in 2005, we only measured the accelerations (which were different than the manufacturer’s claimed accelerations). This was done without an individual standing on the plate.

I also feel that there are some researchers (myself included) that would like to perform product testing so that consumers can be informed of the specs.

We are testing it loaded and unloaded. Believe it or not, you are not the only one who has wondered if the Power Plate, being made of a softer material than steel, affects the vibration characteristics.

I agree that all plates should be tested before (and while, to go above and beyond) they are being used for a research study…..I can only wish that I had thought of this prior to doing the study.

I am more concerned about the errors/limitations of my research than you are. This was years of planning, testing, and analyzing that I put into this project. I could not account for limitations in the study that I was not aware of at the time.

Where is the Peer Review Process?

Out of 41 studies on Power Plate’s own site, only one mentioned testing the platform under load (70 kg) and that was the only load tested (6). Are we to believe all these researchers and journal reviewers simply missed the elephant standing in the middle of the room? See this video by Lloyd Shaw.

These are supposed to be intelligent and highly trained researchers, right? The 41 studies on Power Plate’s own site represent several journals but the NSCA’s Journal of Strength and Conditioning Research (JSCR) is represented well. I counted 12 studies from JSCR out of the total of 41 studies.

This contamination of the literature has allowed marketers and salespeople to take advantage of the situation amidst all the confusion. For example see this video, contrasted with “Vibration Training: The Truth.”

I have had people on different continents (one a well-known researcher) tell me some Power Plate models lost specifications at 80-85 Kg loads and really bogged down at 100 Kg and above. The Australian Institute of Sport has also reported this in a pilot study (4).

Were all these studies just honest mistakes that slipped by? Or, could there be other more sinister factors involved? Power Plate is and has been a corporate partner with the NSCA and EXOS.

    I would add: an intelligent researcher would not use sedentary nonathletes as a control group but rather a group doing the same movements under the same conditions on the same silly platforms but with the vibrator shut off. Comparing to a sedentary control group isn’t a control at all!

    Extra notes: The Truth video. All this was discussed and agreed upon by Power Plate back in 2003 with the much smaller, but quite powerful original unit.

    It was then that we planned to build the machines you see in the video.

    Amplitude is Everything video…… This is why some platforms have 10 mm amplitudes but have produced the same results as those with 2mm. As opposed to 5 times the results this “theory” should have produced.

    In layperson terms, Power Plate was telling people if you move a 1 kg weight around a lot. That is the secret to training. Extra weight and control is not a factor to be considered. Yea right.

    Good background read for part one, but the collaboration in dishonesty between these parties to hide the truth and rip off at risk consumers , will hopefully be an eye opener for some. And one of the reasons to never trust the NSCA want to protect the public.

    We are talking a 100 million dollar con.

    Why we picking on Power Plate ? First company to release machines with fake specs. Fake programs. And hire academics to cover it up. ( hence its involvement with the NSCA )

    davidbendory You are right. But talking to some of these “academics” makes you really wonder if critical thinking is an alien idea to them.

    Important to note: You are not meant to move on the machines at all. As it is like trying to produce an eccentric contraction and concentric contraction at the same time. What you are reading about is the unfortunate results of academics doing cross training on the platforms with zero understandings of the basics.

    Aka….. VT was first meant to be a completely alternative form of strength and conditioning training similar to climbing .

    Eg…. Holding a position while the tree shakes. Then change position and repeat. Covering some basic compound exercise positions. Purely eccentric , purely anaerobic. It can build muscle, build bone , increase overall circulation through basic muscle pump . And it is very fatiguing ….. the larger machines were designed and are being used to help with morbid obesity and stop amputations.

    Because they are so powerful ( take over 300kg and lose zero function ) they are used by healthy people as an alternative workout. You also can not buy them retail because of concerns over misuse.
    It was NEVER meant to replace other disciplines. That is all marketing BS.

    Very Light Vibration and movement patterns were for Physios only.

Hi, my name is Philippa Church and I have a studio in the UK about 30 miles North of London. I really enjoy working in the industry and love the fact that there is always something new to learn. I hope to be able to share my experiences, the mistakes and the successes and really look forward to more and more people finding out just how amazing vibration training can be.
Henrik S Posted On:2009-09-04 00:58:11
Hi all, my name is Henrik Sorensen (Denmark), I'm a customer who was cheated badly by a Dutch company 4 years ago and at this time still not have a vibration platform. The last year I had a lot of help and support from engaged people and specially Lloyd Shaw in getting my money back, thanks Lloyd (case still pending). I mostly read in the forum, and don't contribute much, hopefully that will change in the future when getting a device. If you have been cheated by a dealer I might have some advise to help.
Mike Hair Posted On:2009-09-03 22:28:15
Hi all, my name is Mike Hair, I have been involved in the vibration training industry for coming up 4 years now. My wife Tracy and I run our own studio in the lower half of the south Island of New Zealand. I am more excited about this industry today than I have ever been, . I have seen a lot of ups and downs over the last 4 years and believe we are on the verge of something big. I will answer any questions and help out where I can, but be prepared it will be the truth and sometimes it will be blunt and to the point. I have absolutely no time for lazy people and marketers of bad products.
