The natural movement of human gait is the main principle of Galileo. Due to its side-alternating motion is similar to a seesaw movement with variable amplitude and frequency, Galileo stimulates a movement pattern similar to human gait. Thanks to the rapid movement of the training platform a tilting movement of the pelvis is achieved,  much more frequently than walking. To compensate, the body respondes with rhythmic muscle contractions, that alternate between both right and left side of the body. These muscle contractions are not a conscious process but, are a reflex due to a frequency of about 10 hertz onwards .  activates the muscles in the legs, the stomach and the back are activated right up into the trunk because of this stretch reflex. The adjustable training frequency determines the number of stretch reflex contractions per second. For example, if a training frequency of 25 hertz is selected, 25 cycles of contraction in flexor and extensor muscles occur per second. Also, a training session of 3 minutes at 25 hertz therefore causes the same number of muscle contractions as walking a distance of 4,500 steps.

The amplitude and frequency can be changed continuously ,independent of body weight, by the generated vibrations of Galileo.
