WBV machine platforms create a single vertical directional force summed up as hyper gravity. That force moves only in one direction against the gravitational forces of the earth. A machines platform creates upward load resistance similar to the sensations of riding in an elevator. When the elevator moves rapidly upwards, it feels like your body just became heavier.
On a WBV machine you feel the same acceleration force on your body; this force is referred to as G-force. With the load resistance from higher platform speeds you get the additional effect of stretch reflex muscle activation resulting in your muscles working harder without you actually having to try. The machine is doing the work for you. The intensity of WBV training is determined by three key factors; frequency, the speed of the platform measured in Hz frequency (cycles per second). The amplitude, how high the plate travels from its lowest point to the highest (ona pivitol platform, the amplitude is adjusted by where the user places their feet of hands on the platform). And the magnitude of load resistance it is able to generate measured in G force.
WBV machines work by generating vibrations from the base plate. Vibrating forces are then transferred throughout the body. Low frequency (14 Hz or less) vibrations relax and refresh the body with massaging effects, higher vibrations (14 Hz and higher) will cause rapid and intense muscle contractions. Muscles respond with a rapid stretch-reflex, an automatic response in which the muscle tissues contract and relax peaking at 26 – 27 contractions per minute, shown by heightened electromyogram (EMG) activity. Due to this subconscious contraction of the muscles, nearly 100% of the muscle fibers are used compared to 40 – 60 % in traditional resistance training through conscious voluntary movement. It is very important that the user of a WBV machine be acclimated slowly. As you begin stay at lower frequencies, below 14 Hz. This is why we believe all WBV machines offer some value to the consumer and the reason we recommend an entry level, low energy WBV machine for people with limited budgets or those not willing to make the lager investment of a high energy platform before testing the waters, so to speak.
Once comfortable with WBV the user can consider moving on to a platform which the frequencies can be increased to the optimal 24 – 30 Hz range found on high acceleration and true WBV machines. At this time, the user can increase their duration, or time of their WBV training protocols. Advanced users, such as athletes, can increase the strength training effects by adding additional weight, in the form of a weight vest, resistance traps or dumbbells to further and continually challenge.
Contraindication for Whole Body Vibration Machine:
Conditions that are not suitable for use on WBV machines are:
- Gallbladder or kidney stones
- Recent wounds from an operation or surgery
- Recent fractures
- Acute inflammation/pain
If you suffer from any of these conditions please confirm with your doctor before use:
- Acute Thrombosis
- Serious Cardiovascular Disease
- Metal implants
- Artificial Joints (recent)
- Acute Hernia
- Type I Diabetes
- Recent infections
- Severe Migraines
- Malignant tumors
- Recently Paced IUD’s, Metal Pins, or Plates
- Recently implanted stents
Warning: Please consult a physician or physical therapist before using the whole body vibration machine if you suffer from any of the conditions listed above. This device may not be suitable for all users. Strong vibration affecting the neck and head can occur when using positions other than standing, consulting a physician for approval is recommended. Failure to use appropriate caution could result in serious injury. Misuse of this machine may result in serious injury.
User weight must not exceed the manufactures weight specifications. Caution:
Stop exercising if you experience chest pain, nausea, dizziness or shortness of breath. Begin using WBV at lower frequencies, once comfortable; make increases slowly and if you begin to feel at all uncomfortable stop use immediately.
For this reason we have taken the approach of evaluating, then categorizing each machine we offer for resale. Ensuring the prospective buyer the most accurate expectations of performance and in turn, outcome regardless of what the original vendor may say or market as a new offering.Look at it no different than a safety certification necessary to transfer ownership of a used vehicle.
Please keep in mind that most whole body vibration machines in the market offer a minimum benefit in exercise to the masses, and are better described as a full body massage machine. These machines on average have a maximum frequency around 14 -16 Hz, producing 4 – 6 G’s of resistance force on average. We categorize the majority as low resistance, entry level platforms. The ideal user being anyone below base line fitness levels like most seniors are today, or those with mobility limitations. With time and consistent use, it is possible for the user to move on to higher resistance platform, should motivation and the increased investment be justified. Another reason we encourage the beginner to invest wisely avoiding the sometimes inflated pricing of new, by searching out a used platform to begin with, as they are plentiful in availability.
Scarcely available as pre owned offerings are the ladder high resistance platforms covering a wider range of frequencies and load resistance. Therefore be prepared to pay the price for superior engineering and performance
