We could categorize vibration training technology into two main categories:
Some refer to a 3rd category, triplanar, however the majority of triplanar platform movement occurs via a uniform motion on the vertical axis and therefore falls under the category of Lineal. This lack of distinction is further supported by the fact that the majority of Lineal platforms, being incapable of delivering movement purely on the vertical axis, also have a 3D component. Lastly, worth consideration, is that some sources claim that 3D vibration is nothing more than a marketing term used to disguise a poorly manufactured platform that cannot control its vertical movement and thus moves excessively in the horizontal planes. With all this in mind, below you’ll find a diagram of the two primary platform types that we will discuss and the typical frequency and displacement ranges for each. Also take note of the other common terms often used to describe each method.
Pivotal: Triangular Oscillating, Oscillating, Side Alternating, Rotational, Tilting, Teeter-Totter.
Lineal: Vertical, Synchronous, Uniform, Piston, Flat, 3D, Elliptical, Triplanar
