HOW IT WORKS?
When using the V-Robic your muscles are not simply passively vibrated, they actually do work as they would in more conventional exercise but with almost no effort on your part. Vibration parallel to the muscle fibers exposes them to brief bursts of high gravity (a maximum of between 1 - 6g depending on the frequency and amplitude of vibration). The muscles are stretched by the vibration and a natural stretch reflex causes the muscle fibers to contract. The muscle fibers contract rhythmically leading to both neurogenic and musculoskeletal adaptations. The neurogenic changes occur most rapidly and lead to greater synchronisation of the muscle fibers within the muscle. This results in improved muscle efficiency, in other words more muscle contraction for the same effort. Over a longer time period your body responds to the demand placed on the muscle by increasing the size of the muscle and hence its maximum power.
Automatic neural responses to movement contract muscles to maintain stability. This improves balance and stability.
Bone is constantly remodeled by the body in response to the forces it experiences. People who are unable to exercise will have weakened bones as in the absence of force, the body starts dismantling bone. Postmenopausal women are more at risk due to hormone levels that encourage bone dismantling over bone building. Vibration exercise exerts forces on the bones, encouraging bone strengthening. [11]
