September 26th, 2006KG, Your reference to amplitude. Do you mean vertical movement? I have followed this forum for nearly 6 weeks now and have learned a bit about the many different machines. Reading about the vibration training interested me enough to make my own unit. I bought a vibration motor from a industrial supply co. that puts out 450 lbs. of force and operates at 3450 vibes/min.
This motor is intended for use as bolted to the bed of dump trucks to facilitate removal of gravel etc. Good power.
I made my platform from a 2′x 3′ piece of treadplate welded to a frame of 3″ square channel. To the bottom directly I bolted the motor. At each corner a 3″ x 3″ solid rubber stud mount shock absorber anchored directly to the floor.
The plate is good size so I can position myself well using weights and dumbells, stretching, etc. However, since I have no vertical movement, Static exercise does little more than vibrate the area in direct contact with the plate.
Also, I am thinking of adding a rheostat to control the VPM on the motor. Slowing down will perhaps produce more movement.
I will replace the solid vibration mounts with air dampened bellows type shock absorbers to obtain some vertical movement. Yet these are expensive @ $70 each and I cannot afford yet. With these modifications I believe I will have a well operating unit at around $1000 expended. So far I am pleased with the results for the money and effort spent.

September 26th, 2006Firstly ,doesnt the Hypergravity go up to 5 mm ? And the Power-Plate to 4mm ?
And KG , time to show us what you really know.
Amplitude is only 1 part of the 9 parts physics equation that makes up a basic lineal sports platform . And thats just partial bio-machinic. It jumps to 24 when you reach full bio-machinic.
I have 5 models with varying degrees of the formula. With another 4 to be released soon. All solid polished steel. With marine electronics. The motors themselves are $1800 each ( 2 per machine )You can not just change one thing , like the amplitude and gain a better result KG. And the fact you are being that simplistic alarms me that you are even allowed near machines or people.
This also shows me you are still getting to grips with Newtons law , ( 3 part equation ) so you are so far behind its just funny.
And i am proud to have my own factory. At least i dont have to resort to buying my machine from the Chinese ( for about 800euro ). Designed by a car bumper moulderer out of plastic that had no history of Vibration Training. Thankyou.
Of couse this is a forum , and you can always come back with the basic 8 part formula to prove me wrong. But i wont hold my breath.

September 26th, 2006Could someone Clarify Scott’s question about amplitude?
- Mark
December 4th, 2006Sorry in advance for the slew of questions for Lloyd: 1/Do you recommend the Wave for therapy, and the Hypergravity for training? 2A/What is positive and negative amplitude? (It seems to be whether the platform is dropping or raising, but I cant find a definition as applied to vibration training). 2B/What are different effect of positive and neagative amplitude? 3/Same for p &n contraction. (I know positive and negative’s meaning when applied to movement, but not when applied to vibration training). 4/What -are- the nine principles of physics? 5/Can I set the Hypergravity home machine at a ‘gentle’ enough level to use with otherwise inappropriate subjects,(my father has an orthotic spacer-plate in his knee)? 6/Power Plate promotes their machines as vibrating in three planes,(up/down, left/right, back/forward), while others say this is a fault that PP didn’t bother to correct. Is there anyhing wrong with back/forward, or left/right vibration? It seems at first glance that every direction of vibration would cause a useful reaction.
- Lloyd Shaw
December 4th, 2006Positive and Negative involuntary reflexes are the opposing reactions of Positive and Negative voluntary reflexes. The amplitude has nothing to do with this reaction.
You will not find reference to this on other sites as most companies are still testing the basic negative platforms , trying to get them right. Most are still argueing about amplitude.I am sorry but i cant give you the 9 part equation i use to reach partial bio-mach. And besides the last 3 branch off as the bio-kenetic feeded back increases. To figures i need to dumb down just so i can start to build a unit.
And yes a home unit should have light enough settings for physio work.
And no , 3d vibration causes shearing on the joints and should be avoided at all costs. Ask any Physio.
And their original advertising ( which i still have ) claims it to have only Lineal vibration. So its not meant to be there.

December 9th, 2006I love the new format!
This is so much easier to follow…

December 15th, 2006I have read the article on Sprinting “No marked improvement for sprinters” I found it interesting and I’m not knocking it as it seems a very constructive report based on correct method of testing, however - it’s like any testing - what were the parameters used?
This test used very good sprinters - my question is - at the top of your game what should you expect to see gained in 5 weeks? I have had to use different machines in the
Correct order before you “peak” prior to competition. And the basic build-up
is 8 weeks.Secondly what machines were used for the test? I have used Vibro-gyms, Power plates and the Vibra-train machines and they are like comparing 2 litre, 3 litre and 8 litre engines so I’m not surprised by these results The Vibra-Train units have been developed at a different level. Plus what were the exercises used during the training.
I am always looking for ways to naturally increase strength and my event is jumping so I have found the Vibra-Train machines fantastic. Please note that I also sprint now but did little before vibration training as I didn’t feel I was fast enough.
When you have jumped as high as your expectations and normal training have let you, you seek alternative safe and natural methods for the smallest and hardest gains which take you to new personal bests at the top end. After four years of 1-2 cm increments I had a 4cm gain in my first year and a further 2cm gain before bruising a heel in competition.
Had I been able to continue at the same rate I’m sure I would have had a 4 cm increment for 2006.
I am running faster and bounding further. One of the main reasons for this is that my coach and Lloyd sat down and we learnt about vibration training and Lloyd learnt about the high jump technique. Lloyd also came down and watched me jump and was able to design a programme with exercises unlike exercises one would normally do in commercial environment.
In fact I am sure with the other machines would not have received the gains that I have so far, in fact if I am away and have to use another machine I feel like I’m driving a Mini maybe I have just been spoiled too much?
I have two junior athletes training with me who have never lifted weights and have increased their 100m time by 1 second and a 10cm increase in the high jump. Yes they are young but the vibration training is the only power work they have done. It’s safe if it’s supervised and the young athletes have had no injuries, in fact it’s the balance and stride length gains which seem to be the most beneficial right now.
You must remember that we have been on a longer programme then 5 weeks and our exercises are developing as we gain more strength. It’s too easy to take a small sample test result and draw conclusions from this. You can design any test to get any answer you want. The real test is in continued use and the end performance. This shouldn’t stop you further investigating vibration training for sprinting gains. But before you go too far down the track talk to Lloyd and make sure you have the right information and machines for the results you require.
I know the test was for sprinters and I am a jumper but from what I have seen from my young athlete’s leaves me in no doubt that vibration training does offer benefits and I would love the same test done again in conjunction with Lloyd’s machines and his exercises. Food for thought!
New Zealand Representative Athlete
Yes , I must say I have been surprised that other athletes have not pointed out the very obvious flaw ,in the fact the test ( to date ) have all been on machines being marketed for weight loss.
What where they expecting , speedy cellulite reduction ?
My guess is they have only thrown athletes into these tests in the hopes of a positive result, to be used as marketing.
Complete waste of everyones time. And cant believe any Universities fell for it.
- Nick Morris
December 18th, 2006I have linked with a number of universities to begin a series of studies, with a range of machines the technology of which I own, and that have specific applications for different results.
1.) Elite sports performance
2.) Stress Management
3.) General population fitness parameters.
Pilot work begins in the first week Jan’07 - which will help define the exact parameters of full clinical research.
I will keep everyone up to date.Would love to hear of any further research anyone is currently undertaking.
Happy Holidays.
- Jeff Simons
December 19th, 2006Are there studies showing improvement among sprinters with vibration training? If not…I have to go with the study’s findings rather than just badmouth it. Show a study to the contrary among sprinters. Or are’nt there any? Until people who call the shots in this industry get some solid science behind them…it’s but a VERY expensive thigh master. Snakeoil has never been so pricey. Karmically…you pushers of this nonsense are screwed!!! “Vibration Training For Sprinters-No Marked Improvement”
- Nick Morris
December 20th, 2006Hi Jeff,
I am actively participating in committing to many studies to provide more empirical evidence of the magnificent benefits of WBV, and particularly the specific frequency, amplitude and actions to create the best results for target populations and their respective goals.Past actions of people are out of our control. Our immediate thoughts and action steer our future. Live in the now. What actions would you like to take now, that can provide further clarity on WBV? I suggest that I will assist you with eqpt if you have any university or research group that are ready to commit to undertaking further study in this field. You can input direction on a study that will either prove or disprove your current thoughts.
Our perception is merely our current evaluation of thought.
Happy Holidays.
Have a perfect day
Nick - Jeff Simons
December 20th, 2006Thanks for the “Tony Robbins” pep talk Nick.
I saw that someone on here is going to post a chart of basic positions sometime in the future. Other positions or regimens that might have helped the sprinters show-any marked improvements- no doubt won’t be displayed. Because more than likely they don’t exist.
Guys who manufacture or design these things instead of showing their own independent rigorously tested studies to refute actual ones like the one posted here only badmouth them. They do this because they are either to lazy or know their machines would’nt add up so why dispense with the mystery?
Are their any books on this subject that has been around fo 10 or so years? Any performance(sprinting) training regimens with position charts for these machines or other therapy type settings? Do you have to “know who to talk to” to get this info?Information is truth, one this industry is apparently very careful not to divulge or disseminate.
Because maybe if the truth were really known…these guys would go market something much more useful….like a Salad Shooter. They would probably just charge you 10 grand for it.Please folks. Demand information…and don’t be a sucker.
Jeff Simmons….
Information + education is the key.I think you are missing the education part of whole thing. Not just reading someone elses homework which is what you seem to want to base your sole opinion on.
This way of forming an idea about someting offers you no protection.
If you had done “any” reading on this particular subject you would already understand why tests have not been completed.
The first sports model was only released this year on 17/5/2006. At a huge cost.
All older units I have seen are being marketed along health and fitness lines. Which is to the standard they where built to.
I have yet to see ” makes you faster” on any advertising material.
To give you an idea of what is involved in making a sports model. The prototype is 320kg. And thats only the small version of the finished product.
It cost me over 40k to build.
And we dont sell them and havnt charged athletes to use it.
Also a question for Jeff…..
Even if you did have multiple positive university studies on the units. How would you know you are on the same model as the one used in the study ?
- Jeff Simons
December 21st, 2006Lloyd,
quoting directly from your site under the sport specific-speed section::::
After just a few short training sessions on our machines, those barriers will be gone, helping you to move faster than you ever thought possible.
:::
So technically you did’nt say “make you faster” on your website advertisement….but shown yourself to be what you really are. A marketer. It’s ok, just admit to it and embrace it.
If you are going to make statements like that without any studies backing it up(refer to the Vibration Training-No Marked Improvement in Sprinters above) nor regimens that include positions, duration, hz and amplitude settings-I suppose you can as a marketer. Scientifically though, you just not to be taken seriously.
There will still be a target audience that will overlook and not demand factual scientific studies and detailed regimen specifics to achieve-in this case an improvement in sprinters performance. It’s just likely they don’t have much money to spend. Typically these people are busy hearing voices or telling passerbys on the subway of their recent “alien abduction”. So I’m sure you won’t be ignored Lloyd(:
Please all, demand these detailed regimens and studies from anyone that would attempt to sell you or “educate” you about the modern day version of the 1950’s era “Jiggler” Vibrating Strap machine or WBV training.
All new forms of training breaks down barriers. Both in the mind and body.
The fastest men alive train themselves nowdays. And constantly try new things. They do not limit themselves to the experiences of others. Such as you.
So yes I stand by my words.
Sorry I cant take you seriously when you refer to a massage belt in the same sentence as Vibration Training.
I would like to make a point here about Jeffs mentality and why it has no place here. He is the perfect example so I simply cant let it go by without a comment.
He is a consumer. He consumes others ideas and efforts after ” everybody else is doing it”.
That is also why he views everbody as either a marketerer or a punter . Not realising the “developers” of technology pre-date both and take the risks others like him will not.
Henry Ford did not become famous because he built the Model-T. He became fomous because he built the Model-T and wasnt happy with it.
I would lay money on it that Geff drives around in the result of that exact mentality.
Writing into a ” new technology ” forum. With the limted view of a ” follower ” is not the best look. And confusing two completely different technology’s doesnt help his cause either.
All I can say to athletes who are reading this is , I am willing to put my money where my mouth is. I am building units at my own expense that are going into a stadium in N.Z. And from there selected athletes will do trails. The reason I am not worried about the outcome is because I know my stuff. This technology can and will increase performance. Just let us finish it before you judge or dismiss it.

December 25th, 2006Lloyd,
I’ve perused the banter here on this thread and believe that there is a way to answer and silence the argument J. Simons makes regarding WBV.If you have tests on your unit provide a link. If you don’t have tests or studies you could at least provide a training regimen with one of the models of your machines(hz, amp, position,#sets,duration 3 weeks on one off etc.) that would logically provide an increase in sprinter performance.
It all seems simple enough.
- KG
December 25th, 2006Wow.
Jeff.
You have Lloyd pegged 6 ways from Sunday.
But I would caution you not to write-off the entire technology just due to lloyd’s wriggling away from giving you straight-up answers. MANY people have been helped by this technology. I’ve done som searching around due to your post and found that the powerplate and pneumex websites do offer some of the position guides and training regimen info you thought would be readily available in a legit industry. Just because one can’t put up does not mean the entire industry is afflicted with the same malady.Please research more. This technology is truly amazing.
KG
The reason I have not put up the exact programs for everyone to follow is you dont have access to the units yet . If you did , I would be training you personally.
The Hz , amplt , duration and time spent on units is not enough information for performance gains.
This minimalist type information is the territory of marketers like Power-Plate and countless other cheap companies. They rely on this tactic so they can fool an athlete into thinking ” all machines are the same . So use mine. Its the program that counts. ”
Wrong and untruthfull.
A N.Z. rep athlete has already been on here earlier to explain this point. And she was speaking from experience.
Maybe reading her post again will help.
KG….
you call a company that sold fake units to handicapped people a ” market leader “.So you asking for more research is a bit on the nose dont you think ?
- KG
December 26th, 2006Lloyd,
Because you were not forthcoming with J.Simons and other posters asking you for detailed info regarding how exactly people are to get faster using the machines i.e. WBV I simply tried to mitigate the situation and in the spirit of blogging-”help a brother out.” That’s all. KG should not have to do such things to uphold the standing of WBV as far as efficacy goes, but due to my caring for this technology and the doubters who would benefit if they only knew….it was incumbent upon me to do so. Hopefully he and other doubters will review the specifics(available at Pneumex and PowerPlate-the veritable industry nameplate) of regimen training and hold WBV in a better light.
Just because you see the need(hmmmmm…) for lack of transparency does not mean innovators in this field do. As displayed by their detailed website postings. Hopefully Lloyd the new year will bring about a more forthcoming and transparent approach to this field. For the good of the entire WBV community. Please join me in making this a reality.Sincerely
KG Kg….
is there seriously something wrong with your understsanding of the situation. Power-Plates only detailed website postings are from others machines they only claim are theirs. But are not.How in any way is that a “forthcoming transparent approach to this field” ?
You seem to be missing common sense or ethics or both.
To the rest of you who are truly interested. For a short work up to competition.
The first 3 weeks are on a Required force 2 unit. Concentrating on injury prevention and rebalancing for symmetry in movement.
At week 4 ( with no injury issues ) you move up to the required force 3 machine.
Aimed at basic strenght and conditioning. Worked in with the appropriate drills for you sport.At week 6-8 you move up to the required force 4 unit . This machine is only designed for pressure static work and its whole purpose is to get your body to ‘Peak”.
After this you will need 2 weeks rest.
The full program is 190 days. As thats how long it takes to rebuild and reform complicated tissue like skeletal mass.
- Jeff Simons
December 26th, 2006KG,
While I do appreciate your zeal regarding this technology…I believe you and Lloyd are drinking from the same mug of Kool-Aid and should really get a room together to discuss other expieriences you also may have in common-like hearing voices and being visited by outer-space dwellers.Seriously, I will investigate the resources you have provided. I am vehement in my resolve to not have the average enthusiast fall prey to the likes of those who will attempt to slither out of directly answering queries regarding their products. lloyd has repeatedly avoided basic answers as can be viewed above in previous posts for information. The grasping at straws he attempts when -NOT answering- basic questions is expected however. Remember the scene in Wizard of Oz when Dorthy saw that the wizard was just a flustered showman behind the curtain? Until Lloyd answers with honesty, we can all take heart that at least he has been exposed for not only a loss of words. But also a loss for answers. Here’s to hoping lloyd and others of his ilk…get a clue.
Jeff Simons…..
I fail to see what of your questions I have not answered.You dont have access to the machine , so giving you entire programs is a waste of space on this forum.
It became very obvious during your first few blogs from you that Physics is not your big subject. So trying to translate those ideas to you would also be a waste.
Not to mention boring for most readers.
The exact science needed to make anyone faster is not for this blog. I would need to write a book. This has also been explained to you.
An experienced international athlete also tried to answer your questions in the best way she could.
It would appair it is not answeres you are really after.
- Merrick
December 26th, 2006LLOYD,
your answers ONLY support jeff’s assertions.i posted a question(s) to you have not answered.
WHY Lloyd do you continue to respond without giving a detailed answer to the question?
If you don’t have an answer or cannot come up with one I and others will look elsewhere for opinion.
I am in training and looking to employ WBV. I could use thorough input to help aid my training.
All you give to us wanting- is politician speak and avoidance. No wonder jeff has such a crappy view of this stuff.
- Kris
December 26th, 2006Where have you people been? Lloyd has been the ONLY one who has answered specifically all questions that CAN be answered in this kind of forum. You guys sound like someone who just read that it is possible to have by-pass surgery with an inch incision, but conveniently forgot the part that also said it can be done only in certain situations and then demand to know why the cardiologist doesn’t apply the same to all cases and to explain the entire range of possible cardio function/disease/treatment in some 50 words or less.
Frankly, it’s a good thing Lloyd hasn’t tried to attempt the in-depth explanation and then have people who only have had experience with or own the most limited of machines expect to do that same advanced training that he uses a number of graduated machine on those very simple versions. It appears, for those really advanced athletic training programs, that only experienced trainers with the various models would be able to assist you. Other single models just can’t do it all and you have to face it and move beyond the 3 year old’s constant tagging on the skirt of its mother to explain “why” for things he/she just isn’t capable of grasping until he/she has more experience.
Face it, there just aren’t enough studios out there yet with this new technology and it’s in its beginning stages. It sounds like people who have only used basic therapy type machines and have had success for mostly therapeutical needs continue to challenge Lloyd about their machines when he’s speaking about a number of graduated machines designed for totally different results. If you want to risk a lot of money and don’t care about break downs for heavy use when your machines are not designed for that, then fine, but don’t blame those who are trying to warn you about further down the road expectations of those same basic machines!!

December 26th, 2006This is aimed at all the people out there who do not fully understand wbv and constantly slag off people who are leading the world with this type of technology . I own my own studio and am independent from Lloyd Shaw, although without his knowledge and help i would not be where i am today.
I too was apprehensive about contacting Lloyd when I first investigated wbv that turned out to be the worst mistake of my life, it has cost me thousands of dollars and alot of sleepless nights. All the ethical major players are in constant communication with each other, something the dog eat dog corperate world fails to do.
A few people seem to be comparing apples to oranges, to take tests that where done over a short period and compare them to a long term training program is not only irresponsible it is also stupid! If any of you have the opportunity to call into vibra-train head office and speak to Lloyd personally i would encourage you to do so, if not then a phone call to him I’m sure would help clear things up. The best decision you can make is an educated one, i spent my own money flying from one end of the country to the other to seek out the truth, it was the best money i ever spent. Stop wasting your time running back and forwards with pathetic comments and just ring the guy, it will save you alot of head aches. Also if you didn’t notice one of our very own commonwealth athletes has posted a response regarding training may be you should read it.
Regards mike
- Merrick
December 26th, 2006Kris,
I saw on a previous post you specific too asking very WBV quesI saw that KG and Lloyd helped you with.I was doing the same. Lloyd just furthered Jeff’s argument by avoiding each and every time the basic stuff.
On another note i alsou have implantable heart stents and want to use WBV??? You’ve got to be kidding me. only Dr. Kevorkian would give you the go ahead to use these things with that medical device implanted in you.
I’m done confounding lloyd with my questions. I’ll try powerPlate and Pneumex directly. Those guys must be eating his lunch in the market seeing his constant kvetching about them. Thanks lloyd, you make PT Barnum look like an amateur
- mike Hair
December 26th, 2006Merrick,
are you that much of a wally that you would actually waste your time going to power plate, a company that has openly admitted in court to selling fake machines to handicap people, all i can say is you deserve what you get. Good luck I have answered your questions to the best you could fathom. I am sorry if you fail to understand.
To everyone…
The way you pose questions points me in the direction of your education. And I always will answer in accordance with “your” tone of questioning in mind.I can and will do my best to articulate to your ability. Or I risk wasting both our time.
Stents….
Vibration Training has lower risk than jogging…
People with stents have been using the precise equipments designed for them for over 12 months here in N.Z. With their Dr’s clearence . No problems recorded.
My own personal opinion is some bloggers here have another agenda..
And it has nothing to do with furthering this field or others health.
But I am convinced most independent viewers of this forum have already ascertained that.
- Merrick
December 26th, 2006Mike Hair,
If lloyd after repeated questioning won’t divulge/or know basic info regarding training with these units and the regimen/positional information requested,
why should anyone on this board believe the guy that avoids straight answers is talking straight with regards to Powerplate. lloyd won’t I’m going to contact PowerPlate. That simple. A lot of NFL teams use the unit, and I found that the German Football team used them prior to and during the World Cup. All I know is Lloyd’s avoidance is fishy man. If they’re as horrible as you guys say I’ll know. It just is shocking the non-answers to basic stuff. I think its probably pretty telling too. So I’ll give PP and Pneumex a shot. Merrick….
I will repeat why certain information will not be given on this forum.You do not have access to the correct machines.
So any program I gave you could only be mis-used.
Re- Power-Plate
The information on Power-Plate has been freely available to those interested since 2004.
You have seen the concerns raised here on the forum.
I invite you to do your own research and get back to us on the following.
Stolen Awards.
Fake Celebrity endorsments.
University reports attached to models not tested.
Engineering reports from metal units used to sell plastic units.And the big one.. Fake units sold for medical purposes.
Man or Mouse Merrick ?
- mike Hair
December 26th, 2006Merrick,
I fail to see where Lloyd has not answered your question. As he stated earlier if you don’t have access to his machine what good will his program do you? as far as results go (A N.Z. rep athlete has already been on here earlier to explain this point. And she was speaking from experience.) and a man with an experience is never at the mercy of a man with a theory.You are correct, a lot of NFL teams and the German Football team have used power-plate along with alot of other athletes but what they fail to mention is that it was the original power-plate not the plastic stuff they use now.
Hope this helpsRegards Mike
Correct…
Their is nothing wrong with the original Power-Plate. I have 3 myself.- Phillip
December 26th, 2006Merrick, I have been reading the posts on here and there are many people that have asked questions of Lloyd Shaw and been given answers to specific questions. More so than any one else is prepared to do or capable of doing. Mostly Lloyd Shaw seems to have nothing to gain except the honesty and intregity of this industry. If you ignore Lloyds comments regarding Power Plates behaviour, and just do a little research yourself you will see that they have been guilty some dodgy business practices. This is without question, the facts speak for themselves. I have no idea what their machines are like or who is using them. I simply dont care, maybe they do make a good product, However I will NEVER deal with a company or use thier products because of their dishonesty, and it now appears illegal practices.
- KG
December 26th, 2006Good luck Merrick.
Hopefully PP will advise you where Lloyd was unable.
PowerPlate has partnered with the elite training center in the US. Sorry Mike, The German team was trained with the current PP Next Generation unit brought over to Germany just for the World Cup. Their partnership is for two years.I will provide links shortly.

September 26th, 2006
This is very telling. If no performance gains can be attained in elite athletes, how on earth does an amateur athlete or weekend warrior expect to benefit from these machines?
If WBV is something you have your heart(not mind obviously after reading this study) set on, it would be best to look at units with greater amplitude than Lloyd’s garage shop versions-or his Hypergravity poodle home model.
The Power Plate is THE standard with greater amplitude than the copies, but also the maxuvibe I saw looks very interesting with a 12mm amplitude. This is important because without the extra amplitude, you’ll be forced to do dynamic moves on the plate for any hope of performance gain….opening yourself to injury. Injuries do happen…static positions are the only way to go for safety.
Higher amplitudes will allow for performance gain and keep you safe. I’m sure the next versions of Lloyd’s units and Hypergravity will include these revisions….best to wait…or PowerPlate…even Maxuvibe.
