Are you referring to the ratio of vj from static position w/ weight and then unloaded?
With and without stretch shortening cycle. e.g. squat jump and counter movement jump.
Why do you need a musclelab for that? You talking no arm swing?

The "Galileo" stimulates the whole body by tilting slightly around an axle. The person who stands on the machine tries to keep the head and body steady and upright. All the muscles that keep the body in this position are forced to react to the oscillatory movements provided by Galileo, thus exercising them. This stimulation form is currently known as "Whole Body Vibration" (WBV) training. Many studies show that vibrations at the right dose can lead to faster growth and recovery of all tissues. Training sessions of only 2-3 minutes twice a week produce measurable effects.
Muscle power - The neuromuscular system is activated strongly but in a controlled fashion. As the movements are too fast to react to voluntarily the muscles are activated through a "tonic vibration reflex". This reflex activates especially the fast muscle fibers, that are hard to stimulate and can produce explosive power. As muscles bring forward the highest forces on other tissues they serve as stimulators for a healthy development of these tissues, such as bone and tendons. Impovement of muscle power after Galileo training (upper picture, Bosco, in: Clin. Physiol. 1999), improvement of sprint speed, agiligy and jump height in comparance to explosive weight training (Berschin, in: Leistungssport 2003)
Inter- and intra-muscular coordination - In order to use the muscle power in a functional manner the inter- and intra-muscular coordination should be optimal. Vibrations up to 28 Hz have a positive effect on coordination. Vibrations over this frequency cannot be processed very well. Improvement of balance after 1 Galileo session (Torvinen, in: Clin. Physiol. & func im 2002)
Effects on Bone Bone structure responds according to the Wolffian law of Function, i.e. growth and maintenance of shaft and trabeculae follow the course of the trajectories of strain. A healthy bone - this term also refers to bones with primary osteoporosis - will react to maximum forces, which cause deformation of approximately 1500 microstrain, following a precisely determined biological control circuit. The muscles initiate these deformation forces. Current studies have shown that there is a strict proportional relationship between the cross section of bone and the cross section of muscle. Several studies are showing a positive effect of training with Galileo™ on bone growth. Improvement of bone strength (Stress-strain-Index) in bone after Galileo stimulation OSZI and/or hormone replacement HRT (Siegrist, in: Int. J. Sports Med. 2002)
The importance of tilting - The patented tilting vibratory stimulation of the Galileo evokes both horizontal and vertical balance reflexes. Studies show that this stimulation form leads to improvement of power, balance, maneuverability, and improved power in muscles that are responsible for stability, such as adductors, abductors and muscles in the pelvis region.
Damping - The Galileo stimulation is based on the walking pattern, where left and right leg alternately are in contact with the ground. The muscles and other tissues of the body dampen these vibrations. The pelvis is tilting synchronous with the plate and functions as an important damper. Vibrations to the head are hereby optimally damped, which is essential within healthy WBV training.
Dose, variability - The dose of the stimulation is varied through the amplitude. By changing the position on the plate the amplitude can be varied from 0 up to 13 mm. The use of extra weights further improves the training effect.
Frequency - By variation of the frequency different effects can be evoked. At 5-6 Hz (cycles per second) balance and propriocepsis are stimulated, 10-15 Hz is used for detonization and mobilization, and 18 Hz and up is used for training.
Scientific proof
More than 30 scientific studies have proven the functionality of the Galileo. All studies can be found here <galileo-wetenschap.htm>.
- Galileo stimulation induces a post-activation-potentiation of the muscles and improves tendon reflex sensitivity. Galileo stimulation improves the effects of your regular training significantly.
- Galileo training improves power and balance in all people, but especially in low taxable people, neurological patients, and sportsmen who are training at their physical limits.
- Galileo training reduces low back pain and improves lumbar power.
- Treatment of stress incontinence through physio training in combination with Galileo training leads to a significant extra rise in effectiveness from 50% up to 80%.
- Galileo training improves power balance and coordination in neurological patients.
- Galileo stimulation enhances blood flow significantly, especially in peripheral regions.
- The bone quality (noted as Stress Strain Index) improves after Galileo training.
- A short Galileo stimulation prevents loss of tissue quantity and quality (muscle, bone, tendons), and thus maintains the taxability, for example during an injury rehabilitation period.
Fields of Application in Sports - Increasing readiness before training or competition (scar tissue, poor blood flow, arousal)
- Increasing effectiveness of (weight)training through Post Activation Potentiation.
- Enhancement of recovery after training
- Increasing taxability
- Enhancement of recovery after injury
Fields of Application in Medicine - Rehabilitation of force and power
- Rehabilitation in Neurological patients
- Muscle atrophy
- Poor balance
- Poor propriocepsis
- Low Backpain
- Stress-Incontinence
- Osteoporosis
- Blood Flow problems
- Therapeutical applications focussed on metabolism and tissue strengthening and recovery (arthrosis, tendinitis, skin problems).
Many other treatment goals have been noted in clinical practice and are under investigation at this moment. Examples are treatment of the physical status of women after a breast cancer operation, patients with diabetes type 2, claudicatio, rehabilitation of osteo-arthritis, tendonitis, muscle tears, and general recovery.
Side effects:
In many cases, the vibration causes a severe itching in the trained parts of the body. This is evidence of the strong effect on the vegetative system and the blood vessels. With some patients, a too high amplitude or too rapid increase in training intensity can cause circulatory disorders in the form of a fall in blood pressure. This should not be considered an indication of general intolerance but rather a symptom of poor vessel regulation, which can be improved by training with Galileo™.

It just has the bosco protocols built in. See: Bosco, C: Strength assessment with the Bosco’s test; Italian Society of Sports Sciences,
Rome, 1999.
Here are some real world experience and considerations:
a) Great Post Activation Potentiation as someone stated in another post
b) Ugly increase in tendonitis
c) Normally suggested protocols are too voluminous (as usual)
d) There are two kinds (and by seeing the Promex website, seems like there are three…) of vibration platform technologies. Not all vibrations are the same.
Is this due to tightness in the muscles or actual tendon inflamation (its an isometric contraction after all).
I have never experienced this! We have experienced knee discomfort but never tendon problems, itching occurs…but never tendon problems. Is this the achilles tendon?
Does this have anything to do with the use of high speed treadmills?

I think of it more like a “concentrated plyometric” and/or sort of “hypergravity”.

Martn,
I think you were the one who wrote that the vibrations were the best mean for PAP. To date I have to agree.
I should have worded better the phrase re. tendonitis. The vibes seem to exacerbate already existing conditions (both ongoing and latent), especially patellar tendonitis and plantar fasciitis.
Using them for stimulation, and the entity of such stimulation, as we are experiencing repeated training PBs (track sprints) for this phase of the year, probably magnifies such effect.
Does this have anything to do with the use of high speed treadmills?
LOL! No.
Starting next week I will do some testing on two different technologies and their effects on force-time curve, vertical jump and sprint times with sprinters and soccer players.
Sorry for the late response to this thread!
Here is a correspondence from May of 2001 between Matt Jordan (post-grad at the University of Calgary at the time of post) and the Supertraining list. Not sure if he is a member of this board, but I believe he was doing some extensive research on the vibration topic. Hope it helps!
"It seems there has been much interest in vibration training on several different fronts in the past few years. As the research on vibration training and athletics develops there appears to be three main categories for its use:
The first is to teach athletes who are exposed to large amounts of vibration in their sport methods to dampen vibrations. Researchers in Germany have shown that after training sessions on a vibration platform athletes learn to dampen vibration by changing joint angles and more importantly by altering the degree of muscle contraction. This is extremely important for athletes such as alpine skiers and in-line skaters who are exposed to large amounts of vibration during competition. For instance, the vibration frequency at the hip joint during alpine skiing has been shown to exceed 30 Hz.
The second purpose of vibration training is as a warm up tool prior to explosive athletic movements. Several researchers have reported improvements in jumping following exposure to vibrations and in my personal communications I have spoken with German researchers who report an improvement in sprinting performance in their athletes following exposure to vibrations.
The third purpose of vibration training is to use it as an overload effect during resistance training movements. Vibrations are known to cause a reflex muscle contraction known as the tonic vibration reflex, and have also been shown to re-recruit fatigued motor units during maximal voluntary contractions. During the exposure to vibrations the perception of effort during maximal lifting may also decrease. In this manner, the intensity of lifting may also decrease. In this manner, the intensity of lifting would be elevated during the exposure to vibrations and this may lead to improvements in maximal strength.
Despite the promise shown in the literature on the effects of vibration training on strength and power one must be very cautious with its use. For a reference on all the potential health effects of vibration exposure please read “The Handbook of Human Vibration” written by Michael Griffin. Griffin refers to several studies in which subjects exposed to vibration report chest pain, internal bleeding, nausea and back pain. In animal studies exposure to vibrations has resulted in an untimely death. Exposure to vibrations have also been shown to adversely affect muscle proprioceptors for up to three minutes following the cessation of the vibration and this would undoubtedly have negative consequences for athletes.
In my opinion vibration training definitely represents a very effective training modality but our understanding of its effects on athletes must improve. The interaction of frequency, amplitude, magnitude, exposure time, posture, the use of additional weight during exposure, the frequency of use/week, and the potential negative effects must be clearly understood. One has only to refer to the range of treatments and effects found in the scientific literature to observe the dependency of the biological adaptations on the vibration parameters.
From personal experience I can attest to the impact of whole-body vibrations. I have trained on several different vibration platforms and have even tried a vibration leg press-all I can say is that it represents a different level and type of fatigue. I would not be comfortable using this training method with any of my athletes until all the implications of vibration training are more fully understood.
I realize that I did not include references for any of my comments. If you are interested in having these references please feel free to contact me." 
given the fact that vibration recruites such a large number of MU’s in a prety safe way, wouldnt it be benificial as a CNS stimulation in a taper phase?
The current issue of Ironman has a non-terrible article on vibration with some actual citations.
Yes it probably would be.
sweet:p ill actually try it in the indoors, now, see how it goes
I think this sums it up nicely. Do not over use it and use machines that have been designed to apply appropriate frequencies and amplitudes etc. Also if using vibration then what will you do with your plyometrics?
Also if using vibration then what will you do with your plyometrics?
you’ll probably have to replace some of the plyometrics for vibration, but it could have its uses, i mean, if you have a painfull knee, it could replace plyos till your good to go etc.
Vib is also a nice method of deloading the skeletal system. So you can allow the bone to regenerate while maintaining or perhaps improving your explosive power. I think it would be a nice replacement form plyos but perhaps can’t replace weights? I’m sure others can comment on this better than me.
tc0710:
well yeah, unless you get internall bleeding that is:D
that could be a problem! but is this dose dependant or can it be caused by even small exposure on poorly designed machines?
