Main categories of machine types are: 1. High Energy Lineal, found mostly in commercial vibration training studios and gyms. The vibration direction is lineal/upward eliciting a strong stretch-reflex contraction in muscle fibres targeted by the positions of training program.
2. Premium Speed Pivotal, (teeter-totter movement) used for physiotherapy work at lower speeds and exercise workouts at “premium” speed, up to 27Hz. Both commercial and home units are available.
3. Medium Energy Lineal, the majority of lineal platforms produced. These are usually made of plastic; some have 3-D vibration which is low quality. They give slower and less consistent results.
4. Low Speed Pivotal units. These can give “therapy” benefits and some training. But be prepared to hold perfect poses for at least 60 seconds each pose. Standing lock-legged on the machine ( as often advertised ) will do nothing but increase circulation.
(5) Other machine types are low Energy/Low amplitude lineal and Low energy/High amplitude lineal with varying uses from osteoporosis prevention, therapy for improved blood circulation and flexibility and limited fitness training.
