Whole body vibration machine?
Are sonic, pivotal and tilting whole body machines the same and which one is best?
Whole Body Vibration Training ›
We have invited several manufacturers, WBV researchers, and exercise prescription specialists to participate in our ongoing research effort to bring quality information—without the marketing hype—to our website visitors world-wide. After much investigation we found some manufacturers to be forthright while others offered little or no meaningful data to support the ambitious claims made on their websites. We will be reviewing manufacturers of professional or commercial WBV machines and reporting the results to you, our visitors.
The best Whole Body Vibration Machine?
The question might better be stated “What machine may best help me based on my individual needs?” Yes, there are quite a few manufacturers of SWBV (Sonic Whole Body Vibration) and WBV (Whole Body Vibration) Exercise Equipment. At last count there are nearly 40 WBV and SWBV manufacturers ranging from cheap “knock off” models to high end therapy and training models. So, for this article we are going to answer the most important questions…One, What is WBV? Two, Is this for me? And Three, What do manufacturers offer based on my needs?
What is WBV and SWBV training and therapy technology and how does it work?
WBV is simply whole body vibration by current mechanism of either mechanical or sonic vibration platforms. Both WBV and SBV operate on the principle that creating Hz frequencies raging from 3 to 60Hz can influence contraction and release of muscle. The Hz frequency mentioned is simply muscular contractions ranging from 3 to 60 per second. WBV machines allow a user to perform a variety of exercises. Users can stand on a WBV or SWBV machine in a squat position, move dynamically, stretch, balance, and perform resistance-training exercises by adding external loading. Few protocols exist as the standard; instead, they are determined by the training paradigm of the fitness professional and the limitations, motivations, and goals of the user. Much research needs to be explored before commenting on specific exercise programs…exercise is always an experiment.
How does whole body vibration work in these WBV machines?
WBV machines work with four variables that act on the human body. 1. HERTZ (Hz) are the cycles per second, which is essentially the vibration speed. 2. AMPLITUDE, or the depth or travel of the vibration, is generally measured in millimeters, and is a factor that determines intensity (most machines have adjustable settings ranging from 3 to 60Hz). On a stationary WBV platform, which aims to send vibrations in a vertical or lineal direction, users can change the distance the vibration travels, usually from 1mm to 10mm. On a tilting or pivotal platform, users change the amplitude by using a wider foot-stance. On a sonic or “sound driven” SWBV machine, which employs lineal vibration, users turn simply up the intensity – which is nearly actually the “quietest” machine. 3. MAGNITUDE, or the acceleration power of the movement, is a measure of the mechanism and its movement through space and time. 4. DURATION, or the amount of time a user spends on the machine. A users or fitness professional adjust these variables determined by the users results and type of machine.
The vibration created by these machines affect the body in a number of physical reactions. As the vibration plate or “working end” of the machine vibrates the body reacts by sending signals to the muscles to counteract the displacement effect of each single vibration. When a lineal vibration is sent through the body there is a “positive” force causing momentum away from gravity. And, of course the reaction of this force is the pull of gravity. The greater the vibration intensity, the greater the amplitude or movement away from gravity. Your muscles contract and relax to offset the effects of “redirecting” gravity. Simply stated, the effect on the muscular system is to add force to compensate for this bodyweight displacement caused by redirecting the force of gravity. Not only the muscles react but tendons also absorb this vibration thereby utilizing their function to support and help muscles leverage bones. Fitness professionals specializing in WBV will use different poses, exercises, external loads, and frequencies in Hz to accomplish different therapy and training goals.
