A
Summary of Research on
Whole Body Vibration Machines
Increased
bone mineral density and balance reducing risk of bone fractures:
Oscillatory whole-body vibration has been tested for the ability to prevent
bone fractures and osteoporosis in frail people. The University of Extremadura
(Spain) set out to test this over a period of 8 months with a control
group that were given walking exercises. Both groups were prescribed 3
sessions per week for 8 months. Vibratory training was approximately 6
minutes per session. Each walking session was 55 minutes of walking and
5 minutes of stretching. The results after 8 months in the vibratory training
group was that bone mineral density was increased by 4.3% compared to
the Walking group. Balance was also improved 29%.

No bone
mineral density improvement over 8 months with vertical vibration training:
A study performed over 8 months with
3-5 sessions per week lasting 4 minutes reports no enhancement of bone
mineral density. Jump height was improved by 7.8% however.

Improved
circulation, increases in muscle flexibility and strength, elevated secretion
of hormones important in the regeneration and repair process:
Whole-body vibration has been tested in this are by measuring skin blood
flow. A study performed by Loma Linda University, California, compared
the effect of cardio exercise, weight bearing exercise and vibration training.
They found that short duration vibration exercise significantly increases
skin blood flow compared with other exercise groups. In fact on average
skin blood flow was doubled for a minimum of 10 minutes following vibratory
exercise.

Walking
ability in the elderly:
The Kawashima Orthopaedic Clinic in Japan conducted a study of the effect
of whole body vibration on elderly persons (average age 72) undergoing
routine exercise programmes to improve balance. Vibration sessions were
4 minutes once per week. After 2 months, those using vibration machines
exhibited significant improvements in walking speed, step length and the
maximum standing time on one leg. No significant changes occurred in patients
that performed the routine exercises alone group. Whole body vibration
exercise was safe and well tolerated in the elderly.

Vibration
training as effective as going to the gym:
The Physiotherapy
Department at Katholieke Universiteit, Leuven, Belgium concluded that
standing on a vibrating surface is as beneficial as going to the gym for
improving leg strength and speed of movement. The study was for 3 sessions
per week over 6 months.

Human Growth
Hormone increase and Cortisol reduction:
In a study carried
out by the Societa Stampa Sportiva, Rome, Italy, 6 minutes of whole-body
vibration treatment was shown to induce acute responses in the hormone
profile of the men studied. Whole body vibration significantly increased
the participants' levels of Human Growth Hormone and Testosterone while
simultaneously reducing Cortisol levels. The study found that the biological
mechanism produced by vibration training is similar to the effect produced
by explosive power training (jumping and bouncing).

Improved
oxygen update during Whole Body Vibration Exercise:
The university of
Berlin investigated oxygen uptake during different types of exercise with
and without whole body vibration. A further study indicates
that metabolic power in whole-body VbX can be parametrically controlled
by frequency and amplitude, and by application of additional loads.
