Vibration is the driving technology behind whole body vibration machines. In this write-up, I shall try to characterize vibration from the perspective of a whole body vibration machine. In addition, I shall also look into how the vibration machines behave under different conditions with respect to producing vibration.

Amplitude and frequency of vibration

Vibration amplitude is the total movement that the machine will make in any one direction, before it changes its direction to continue with the vibration process. And frequency is the total number of direction changes that the machine will make every minute. So the amplitude and frequency, combined together, determines how intense the vibration is going to be.

A high range of vibration frequency is great, it also important to have a good range of vibration amplitude along with a good frequency range. In many cases, the vibration amplitude factor is not specified by the manufacturers, although the vibration frequency is often mentioned as that is more popularly understood by potential buyers and “regular” (non-savvy) users. You would want to get a machine with good vibration amplitude as well as a high range of vibration frequency, as that gives you the flexibility to improve the exercise quality significantly by selecting the different ranges that you want at different times.

Random vibration versus healthy vibration

It is of utmost significance that the directions of the vibration are well-controlled. The vertical motion (up-and-down) is the motion that will detoxify your body and keep it free from a number of toxic substances. The detoxifying motion needs to be purely vertical in nature. Vertical motion is the best suited to detoxify human bodies. It will also help in releasing lymph. Similarly, the horizontal directions (left-right and front-back) need to be also controlled with high precision. Random and uncontrolled vibration is never good for the body as you won’t be able to regulate the machine to cater the desirable vibration to your body given your physical conditions.

Absorbed power/vibration and friction wastage of machine

As vibration machines age, they develop frictional wastage. This is because a part of the vibration does not happen in the desirable direction. The fraction of the friction that remains usable after the wastage gets translated into actual vibration that benefits the body. It is this actual vibration that gets absorbed by the body and provides the body with the necessary exercises. In fact, as one considers a machine with lower manufacturing quality, one would observe a sharper degrading of the machine with higher wasted friction getting generated. Some machine brands seem to do worse than others on this front.

There is one more hassle associated with development of off-the-angle unusable friction. This friction ends up vibrating the floor beneath. Vibrating the floor beneath is not a good option. Getting a good-quality sound-absorbing carpet/mat is important, if you are going for a machine known for causing relatively higher friction. Otherwise, your family and neighbors living in the same apartment, on the same floor as you, or those living in the floors below yours, will experience significant vibration-related energy loss.

Machine efficiency decay

As the machines age, as it happens with any machinery, they start degrading. The friction generated shoots up north. The efficiency of the power produced starts reducing with more power getting wasted. After 5-7 years of run, the machines that had started their life using 10 amps will start using 12-13 amps often enough. This makes it imperative to use whole body vibration machines having track record of degrading slowly over time, as that will help you use the machine most efficiently for the most prolonged time duration possible.

Effective frequency of vibration

While a frequency rating is assigned to every vibration machine, but there is a catch to that. The frequency benchmarking is done under zero-load condition. That is, while carrying out the benchmarking process, there is no weight kept on the machine platform (read: no person is taking exercise on it and the machine is vibration freely without having to move anyone around). And that’s the specification you would see on the machines. While that may be true that the machine can vibrate with the shown frequency, but it probably does not mean anything to you. The same applies to the vibration amplitude.

The effective vibration frequency (and amplitude, for that matter) of the machine that you care about is the frequency that you experience while you are standing on the machine, that is, when the machine is loaded. A manufacturer or a store will normally never specify this. In absence of the specification of load bearing capacity in addition to frequency, your best bet is to use a machine with a powerful motor, and again, look at track records. At the same breath, you need to be aware that some machines get hot before others after running a bit of time, and then start losing the vibration frequency rapidly. Factor this in also.

How do you plan to use the machine?

Not all body vibration machines are suitable for every person. It depends upon the way you are going to use it. Are you planning to exercise (and hence, jump or move around) while vibrating your body on the machine?

If yes, then you need to take a machine with a powerful motor. This could mean you need a linear vibration plate based device, or for heavier exercises, a tri-planar machine. If no, then you don’t need to choose powerful motors. A regular pivotal vibration machine will be sufficient for your requirements in this case.

Irrespective of the manufacturer, the lower end machines will typically be the ones on which you can take stable exercises, but not jump around too much. Normally, the vibration they produce is pivotal in nature. Note that not each type of vibration is suitable for everyone depending upon their health conditions. So pivotal may be just the right kind of vibration for you, especially if you have had serious injuries in your earlier life. Hence, just because the machine is “lower end”, it does not mean “bad” – it just means “catering functionality that can be offered without being expensive”. On the other hand, if you plan to jump around and take some exercises, then go for one of the linear vibration machine models. Normally, these are the mid-range machines from the manufacturers.

The highest-range machines from the manufacturers are the ones meant for the heaviest of exercise takers. They are often expensive as they are the top-of-the-line (the prices may starkly vary, up to a few thousand dollars, depending upon the brand and quality) machines meant to showcase the best performance that the maker can produce. However, unless you are sure that you need such heavy exercise, don’t let your ego make you opt for these top-end whole body vibration machines. Brilliantly made as these machines often are, using these may have an implication.

One of the most popular terms for vibration machines is “triplanar vibration”. Unfortunately, it is also the least understood version of vibration. While many people do understand that a triplanar whole body vibration machine will move the body in three directions, there are a few primary issues with their deeper understanding of the process. The issues are: (a) some people don’t understand the three actual directions of movement, (b) some people don’t realize the fact that these movements are complex and hence require perfect frequency control to be beneficial and (c) many don’t understand that the benefits for triplanar vibration do not cater to everyone – in fact, it may be counter-productive for a number of people to go for these machines.

Typically, there are up to three kinds of vibrations built into machines.

  • The pivotal vibration – the machines moves only in the up-down (vertical) direction.
  • The linear vibration – the machines move in two linear directions.
  • The triplanar vibration – the machines move along three planes – the two horizontal planes (front-back and left-right) as well as the vertical plane (up-down). This write-up covers the details of triplanar vibration.


To start with, triplanar vibration machines are expensive, as long as we talk about a machine with true triplanar vibration, with each plane receiving a reasonable amount of vibration, and as long as we care about machines with adequate vibration frequencies. No reasonable triplanar vibration machine will be priced at anything under $3,000 at the time of writing this. Some of the very best triplanar machines will be placed at higher than $10,000, making them extremely expensive. However, unless your requirements are exceptional, you ought to be fine with the usual $3,000-$5,000 machines.

The reason that these machines are expensive is simple – they need to produce vibration along three planes. That requires machinery which is much more complicated compared to the single-dimensional pivotal or two-dimensional linear or hybrid vibration machines. So the manufacturing cost will be high for these machines, pushing the retail price in an upward direction.

Professional grade

The important aspect to understand before choosing a triplanar whole body vibration plate machine is that these machines are professional grade. They produce extremely “heavy” vibrations. These heavy vibrations are suitable for people with body building objectives. These are also excellent vibrations for sportspersons taking heavy exercises for their bodily requirements.

So, if you are a sportsperson or a body builder trying to develop and maintain your body to a professional grade requirement then you are in for a wonderful experience if you choose to go for triplanar vibration. Your muscles will receive the desirable volumes of all-round vibration with these machines. You will probably be able to meet your health objectives quickly.

However, if you are a “regular” (non-sports etc.) person trying to maintain your health and are taking vibration exercises for those purposes then a triplanar machine may not be the best option for you. You would probably be way better off with a machine that is either pivotal (mostly) or linear (in some cases). So if you are from this category and still thinking of getting a triplanar vibration machine then you may want to reconsider your decision, or at least spend a deep second thought towards it.

Vibration directions and frequencies

Whole body vibration machines driven by triplanar motor will, quite expectedly, help your body vibrate in three directions. In almost all the cases, you will receive adequate movement along the two horizontal axis (x-axis and y-axis). However, the vertical axis (z-axis, moving along the up-down direction) movement is not the same or equally good in all the machines.

Depending upon the z-axis (vertical) movement, these machines can be practically classified into three different types. In one category, the vertical vibration is low – often at the range of 2-4 mm. These machines are good for muscle-building but not for detoxification or joint pain management. In the next category, the vertical vibration will be in the medium range – around 5-8 mm, often with some reduction in the horizontal axis. In this range of vibration, there is a good balance between body building and health maintenance (such as joint pain management and detoxification) – although people with significant back pain or joint issues should still avoid these machine. In the third category, the horizontal vibration is significantly reduced but vertical vibration is majorly increased – often to higher than 9-10 mm. In this zone, the detoxification is at the highest levels because of the vertical movements. Unless you have the very best machines, the horizontal movement will be reduced with these machines.

The other point of significant importance is the frequency control. Because of the nature of the associated vertical movement, the frequency needs to be high enough for the impact to be felt, but not too high so that there is no damage done to any part of the body (bone or muscles). In general, a lower vibration frequency limit below 25-28 Hz is not acceptable, as that will normally not produce much vertical vibration at all. On the higher side, the vibration needs to be less than 48-50 Hz. In fact, most people would prefer it to remain under 45 Hz. Anything higher will be too heavy for almost all practical purposes for even the heaviest of exercise-takers.

The vibration direction also plays a critical role on detoxification. The higher the vertical movement happens, the better quality of movement your lymph and glands receive. This leads to an improved quality of body detoxification and gland/lymph health maintenance. With the highest-quality triplanar vibration machines, one will receive sufficient vibration of the whole body along each of the three directions – front-and-back, left-and-right and up-and-down, leading to adequate and well-rounded physical exercises.


To conclude, triplanar whole body vibration exercise machines are great if you are a heavy exercise-taker, or want to maintain your health on the higher side of efficiency.
