Vibration training method
A. Vibration of a plate - vertical ("pestle"-like)
When standing: Stimulation of only the lower members
The user stands on the axis running vertically
unphysiological due to constantly acting, vertical impact on the skeletal system
B. Vibration with a rocker
When standing: Stimulation of leg-, pelvis-and back- / abdominal muscles
The user stands on both sides parallel to the central motion axis
Simulates a part of the physiological walking movement
C. Vibration with two alternate and variable side-alternating platforms - Wave Principle (X-SAM)
When standing: Stimulation of ankle, leg, pelvis & back-/abdominal muscle
The user stands displaced by 90 ° in front of the motion axis in the separate platforms
Completes the physiological walking movement by participation in the bend-/stretch movement in the upper ankle joint
Meanwhile, the side alternating vibration method that is almost invariably applied in medical training therapy continues to prevail over the vertical systems. Side alternating vibration training has become indispensable especially in the inpatient and outpatient physical therapy as well as in the fitness area.
Rocker method used to date
A wider step position inevitably results in correspondingly higher amplitude of feet deflection. If the amplitude is too high and the training therefore too intense, the legs must be placed close, or the user bends his knees down more strongly. This restricts the training. Because older users and patients require at least a hip width stance for their stability. By flexing the knee, part of the effect is lost on the torso muscle. A "squat" is very difficult when the legs are positioned closely and hence also unphysiological. This is how movement exercises on rocking devices frequently end. The less trained the user is, the more difficult and limited is the application. For older exercisers, the more uncertain is the close positioning of the legs. These individuals therefore have a difficult start into the rebounding exercise.
