Vibration Plate Machine FAQ

4 types of vibration plate

According to their mechanical mechanisms, vibration plates can be categorized into 4 types.

4 types of vibration plate
  1. Pivotal Oscillation Plate
  2. Linear Vibration Plate
  3. Complex Motion Plate
  4. Solenoid Vibration Plate

Each of these types has different movement pattern, parameter and impact to human body.

To select a right vibration plate, you first need to know what are the available types.

What is a pivotal oscillation plate?
Pivotal Oscillation Plate

A pivotal oscillation plate uses a planar 4-bar linkage device to produce its reciprocating movement.

It moves like a see-saw around a center pivotal point ~ literally pivotal oscillation.

Pivotal oscillation plate is usually designed to run on a frequency range from 5Hz to 15Hz.

What is a linear vibration plate?
Linear vibration plate

A linear vibration plate uses an eccentric wheel device and a set of supporting springs to produce a forced vibration.

This type of vibration is call linear vibration because the spring force and the spring length-change have a linear relationship.

Linear vibration plate is usually designed to vibrate on a frequency range from 15Hz to 40Hz.

What is frequency?
frequency

The frequency of a vibration plate is the count of its repeated reciprocating movements in one second. Its unit is Hz.

A 35Hz vibration plate means the vibration plate moves up-and-down 35 times in a second.

Some people confuse the vibration frequency with the frequency of AC power, which is 60Hz in the US.

Vibration frequency and amplitude are the two most important parameters of a vibration plate. They determine the vibration intensity.

What is amplitude?
amplitude

The amplitude of a vibration plate is the maximum travel distance of its vibration board between the lowest point and the highest point.

Pivotal oscillation plates are usually designed to achieve an amplitude range between 8mm and 12mm. Linear vibration plates can only reach 3mm to 4mm.

Vibration amplitude and frequency are the two most important factors of a vibration plate. They determine the vibration intensity.

What is vibration G-force?
What is G-force

Vibration G-force is the acceleration rate of vibration. It uses gravity acceleration rate G as the unit for an easy understanding. It is an important parameter that indicates the intensity of a vibration plate.

Vibration G-force is calculated from frequency and amplitude.

In vibration movement, G-force is not a constant value. It changes between the maximum positive value and the maximum negative value in each vibration cycle. Vibration G-force is decided by the frequency and amplitude.

G-force impact on human body

Vibration plate can put a high G-force on the user. It is like to put multiplied gravity on the user. Vibration G-force only last a tiny fraction of a second in a vibration cycle, so the impact on the user is minimal. The short pulse of the multiplied gravity force creates unique stimulation on muscles, tendons, ligaments and bones. Such stimulation is our needed treatment intervention.

What is speed level?

Many vibration plate models use speed level to indicate how fast the machine vibrates. However speed level is not a standard unit. It is defined by each manufacturer arbitrarily.

speed meter

For a vibration plate with 15Hz max frequency, one manufacture may configure it to have 60 speed levels, and another manufacturer may configure it to have 180 speed levels.

Frequency is the standard unit that indicate the how fast the machine vibrates. 15Hz means the vibration plate moves up-and-down 15 times a second.

Speed level does not tell how many times the vibration plate moves up-and-down in a second.

Configuring 60 speed levels for a vibration plate that only runs from 5Hz to 15Hz is not necessary. High speed level configuration is just to make a marketing hype.

Vibration plate can shake your house!
vibration-shake-house

Vibration plate should be used on a solid floor that can resist vibration, like a concrete floor, or a wood floor that is tightly attached to a concrete substrate.

If you live in a wood frame structure house, you should put your vibration plate in the basement or the garage. If used on a wood frame floor, the machine will vibrate the floor. The floor joist will further transmit the vibration to the connecting stud walls, shaking your house. Over time, the vibration will loose the house structure.

using anti-vibration cushion

You can put a thick EVA foam exercise mat beneath your vibration plate to reduce the vibration transmitted to the floor. The effectiveness depends on the solidity of your floor.

Never use a vibration plate in a mobile home.

The higher the vibration frequency, the more intensive the vibration plate can shake the house.

Vibration plate can jump or drift on the floor!

If there is no body weight on a vibration plate, when the frequency reaches a certain level, the vibration force can overcome the machine weight and cause the machine to jump or drift on the floor.

Pivotal oscillation plate has a higher amplitude so it appears more like jumping on the floor. Linear vibration plate has a lower amplitude, so it appears as drifting on the floor, similar to a cell phone drifting on the desk on its own vibration.

This is not an issue as long as you keep your body on the machine when it is running.

VT vibration plates come with suction cup style rubber feet which can hold onto flat floor. However sometimes the floor is not so smooth and clean and the suction feet may not function well.

It is recommended to use your vibration plate on a carpeted floor. The carpet provides some buffer and friction that can prevent the machine from jumping or drifting.

Always stay on your vibration plate when it is running. Never leave your machine running unattended.

Noise level of vibration plate

Vibration plate does not produce much noise when the frequency is below 20Hz. Pivotal oscillation plates usually runs very quietly because they usually vibrate below 15Hz.

Linear vibration plates produce more noise than pivotal vibration plates, when they vibrate above 30Hz.

Excessive mechanical noise indicates a low quality vibration machine. Harsh noise usually means malfunction.

In terms of loudness and annoyance factor, human ears perceive the same dBA level differently depending the sound frequency. For example, 50 dBA at 30Hz sounds much louder than 50 dBA at 20Hz.

VT007 is a very quite linear vibration plate even vibrating at high frequency. It not just achieves lower dBA level, but also largely eliminates annoying high frequency mechanical noise.

EMF produced by vibration plate

Like all household electric appliances, vibration plate generates electromagnetic fields (EMF).

The type of EMF generated by a vibration plate is called extremely low frequency EMF, in comparison with radio frequency EMF generated by microwave oven or cell phone.

Hazardous effects of vibration

Prolonged or excessive exposure to intensive vibration may cause health problems. However, 30 minutes a day using a whole-body vibration plate is not considered harmful. It is attested by millions of users over years.

Clinical trial based scientific studies support that properly use of vibration plate does not pose a health hazard.

There is not a set of regulated safety standard for vibration exposure. US Labor Department and National Institute for Occupational Safety and Health published advisory information on profession related vibration exposure, which is for prolonged continuous use of vibrational equipment and machineries.

Many senior people and physically weak people use vibration plate to enhance their strength and improve overall health conditions.

However, just like it can positively influence your body functionality, vibration can adversely impact your body if used improperly or in a wrong condition.

Who should NOT use vibration plate?

People with certain medical conditions should not use vibration plate.

These conditions include but not limited to:


  • Pregnancy
  • Implant
  • Pacemaker
  • Retinal detachment
  • Motion sickness
  • Kidney stones
  • bladder stone
  • Arrhythmia
  • Epilepsy
  • Seizures
  • Migraines
  • Recent surgery
  • Other serious medical conditions

Negative impacts of vibration plate

Nausea and dizziness are the mostly reported negative impacts from using vibration plate.

Vibration on stomach can cause nausea, and on brain can cause dizziness. Linear vibration plate can transmit vibration to the upper body and head. About 2% VT003F linear vibration plate users reported nausea or dizziness.

First time vibration plate users should always start with low intensity. Knee bent and calf raise can help avoid vibration from transmitting to the upper body. Most people can gradually build up tolerance to vibration.

Pivotal oscillation plates cause less nausea or dizziness because pivotal oscillation plates do not transmit a lot of vertical movement to the upper body.

Some users reported vision blur while using vibration plate. The vision resumes as soon as the vibration is stopped.

Wrong types of vibration and wrong exercise poses can impact your joints and improperly stress your tendons and ligaments, causing injury.

In a vibration exercise, your muscles, tendons, ligaments and bones are impacted, like they are impacted in a regular exercise. It is just that with vibration, the rapidly repetitive impact at high G-force can amplify the positive or negative effect.

Our suggestion is not to let vibration directly act on your ligaments, cartilages, and bones. Instead, you first let the vibration to induce muscle contraction, and then let the muscle contraction force to act on the connecting tissues. It is important to use the right exercise poses.

Vibration exercise recommendation

You can duplicate some regular strength, balance and stretch exercises on a vibration plate to achieve enhance effectiveness.

Squat, calf raise, deadlift, push-up, half-plank and v-sit are the most suited exercises on a vibration plate. These are also the basic exercises that help stabilize and enhance your body core strength and balance.

Other exercises may not effectively utilize vibration plate for muscle contraction, which is the key for vibration exercise.
