Frequency of Vibration Plate

The Definition

The frequency of a vibration plate indicates its reciprocating movement count in one second. The unit of frequency is Hertz or Hz.

For example, if we say a vibration plate vibrates at a frequency of 15Hz. That means the vibration plate moves up-and-down 15 times in a second.


[Frequency of Linear Vibration]

The animations below compare two linear vibration plates, one vibrates at 1Hz, the other vibrates at 4Hz.

1Hz linear vibration 5Hz linear vibration
Frequency = 1Hz
Vibration plate move up-and-down 1 time in a second.
Frequency = 4Hz
Vibration plate move up-and-down 4 time in a second.

These animations are slow motion for demonstration purpose. In reality, linear vibration plates usually vibrate at the frequency range between 15Hz and 50Hz.


[Frequency of Pivotal Oscillation]

The animations below compare two pivotal oscillation plates, one vibrates at 1Hz, the other vibrates at 3Hz.

1Hz linear vibration 5Hz linear vibration
Frequency = 1Hz
Vibration plate move up-and-down 1 time in a second.
Frequency = 3Hz
Vibration plate move up-and-down 3 time in a second.

These animations are slow motion for demonstration purpose. In reality, pivotal oscillation plates usually vibrate at the frequency range between 5Hz and 15Hz.

Frequency is a simple and accurate expression of how fast a vibration plate vibrates.

Speed Level is Arbitrary

Many manufacturers use speed level to express how fast a vibration plate vibrates. However, the speed level does not actually tell the speed. It is just a relative value for its model, arbitrarily defined by the manufacturer. You can not compare speed levels between models.

For example, one manufacturer may program 99 speed levels for their vibration plate that has the max frequency of 12Hz; another manufacturer may program 180 speed levels for their vibration plate that has the same max frequency of 12Hz. Both machines have the same max frequency (up-and-down 12 times a second), but one claims 99 speed, the other claims 180 speed.

It makes no sense to program 99 or 180 speed levels for a vibration machine that only move up-and-down 12 times a second. Bigger number speed level is just a marketing hype, not necessarily means the machine will run faster.

Also, don't get confused between the frequency of vibration and the AC electricity frequency of your power supply.

The Influence of Frequency

Vibration frequency and amplitude are the most important parameters for a vibration plate. The two parameters together determine the intensity of vibration and the energy stored in the vibration.

On the same amplitude, the higher the frequency, the more vigorous the vibration impact on our body.

Most vibration plates have adjustable frequency. New users should start with the lowest vibration frequency and gradually increase the frequency after adapted to the vibration.

Almost all pivotal oscillation plates have adjustable frequency. Some linear vibration plates are designed to vibrate at fixed frequency.

Our purpose of using vibration plate is to transfer the vibration from the machine to human body. The most efficient vibration transfer occurs when the resonance effect is achieved.

[Natural Frequency & Resonance Effect]

Resonance effect is achieved when the vibration frequency of the source (vibration plate) matches the natural frequency of the target object (our body). At resonance, the target object reaches the highest vibration amplitude.

Natural frequency is determined by the object's mass and rigidity. It is in proportion to rigidity and inverse proportion to the mass. Heavier and flexible object has higher natural frequency; light and rigid object has lower natural frequency.

The natural frequency of our body and organs varies because of their different weight and flexibility.

  • Human body as a whole, is heavy and flexible, has a lower natural frequency, range between 5Hz and 10Hz, depending on the person's weight, height and flexibility.
  • Soft tissues are smaller in weight and flexible, their natural frequency is higher than the whole body, ranged between 10Hz and 50Hz.
  • Skeletal muscle as a type of soft tissue is special about its natural frequency. Skeletal muscle can become rigid through contraction. Therefore contracted muscle has higher natural frequency then loss muscle. Muscle contraction plays important role in our body response to vibration stimulation.
  • Finger is smaller and rigid, so its natural frequency is high, between 100Hz and 130Hz, according to research published on National Library of Medicine.

Understanding the natural frequency of our body and tissues, we can better anticipate our response to vibration frequency. We expect our body to be vibrated the most at the input frequency between 5Hz and 10Hz, and our soft tissues to be vibrated the most between 10Hz and 50Hz.

A vibration plate runs between 5Hz and 10Hz would shake the entire body high but not much on soft tissues. A vibration plate runs between 15Hz and 50Hz would not shake the entire body high but vibrate soft tissues more, and stimulated skeletal muscle more.

Pivotal oscillation plates usually designed to run at lower frequency between 5Hz and 15Hz. It shakes the entire body high but not much induces muscle contraction.

Linear vibration plates usually designed to run at higher frequency between 15Hz and 50Hz. It does not shake the entire body high but does induce more muscle contraction.


The frequency of linear vibration plate model VT003F and VT007 (15Hz - 40Hz) are designed to match the skeletal muscle's natural frequency for resonance effect on the muscles, and achieve enhanced fast pace muscle contraction.
