Vibration plate

So-called vertical plates are offered, in which the training surface moves up and down in different frequency ranges. In rehabilitation, side alternating systems (rocker function) are mainly used, in which the training surfaces swing similar to a seesaw. The user stands either on both or one leg on the rocking vibration bar, which alternately moves the right or left foot upwards, or sits on the plate with a foam cushion, for example.

Another possibility is to support the arms on the plate or to stand at right angles to the training surface. When used in a standing position, these vibration plates with rocker function stimulate the musculature rhythmically alternating from side to side in right-left alternation as when walking or running, as well as in alternating tension of the activity of agonist and antagonist. (Antagonist = muscle that relaxes while the agonist – the acting muscle – performs a movement or holding work).

This results in a constant change between concentric (moving muscle function) and eccentric (holding muscle function) muscle work. Both forms of muscle work are necessary for all everyday functions such as movement and holding work (e.g. walking, running, stairs). There are also devices where both vibration slat systems (vertical and horizontal system) can be selected, but the available frequency range is limited.

In the meantime, small, functional and correspondingly cheaper vibration plates are offered for domestic use, which can be used sensibly by chronically ill people (e.g. muscle weakness or osteoporosis). In the last 20 years, numerous studies have been carried out which prove the positive effects of whole-body vibration training on muscles, bones and vessels. However, the research situation regarding the effects of whole-body vibration training is not complete, is partly contradictory and requires further observation. The more precise detection and verifiability of the specific mode of action is above all necessary for the methodological development of the training and as a basis of evidence.

Which training parameters of the vibration plate can be changed?

The desired effect of vibration training can be achieved by changing the training parameters. Which training parameters can be changed?

  • Frequency range (variable between 5 and 30hz, 1hz=1 oscillation/sec)
  • Vibration amplitude (step position larger, smaller, transverse or longitudinal)
  • Starting position on the plate (standing, sitting, supporting with the arms)
  • Time and sequence of the training
  • Frequency of training
  • Exercise selection during vibration
