The Power-Platein Practice
ThePower-PlateinPractice
ThewaythebodyreactstoWholeBodyVibrationtraining
hasasignicanteffectontheresultsitproduces.Themost
importantandprobableexplanationsarediscussedbelow.
IncreasedStrength
Ineverydaylife,gravityhasthegreatesteffectonmuscular
development.Specictrainingprogrammesthatare
designedtoimprovemusclestrengthutilisefastandabrupt
changesingravity,whichincreaseitsinuenceonmuscle
structure.Weightsandotherformsofresistanceareused
toachievethis.
Musclestrengthincreasesthroughresistancetrainingwhen
properprogressionandprotocolareemployed.Thisis
calledsupercompensation
Applicationofvibrationtrainingfollowsthesameprinciples
asconventionalpowertraining-theincreasedinuenceof
gravityiscausedbyincreasedgravityacceleration.Inother
words,WBVcreatesachangeingravitywithoutexcessive
loadsbeingplacedonthemusculo-skeletalstructure.
ThephysiologicalevidenceofthisimprovedmusclestrengthcanbeseenthroughNeurologicalandMyogenicAdaptation.
NeurologicalAdaptation
NeurologicalAdaptationoccursasaresultofexerciseand
isthereforeoftenreferredtoasthefastadaptation.The
processcanbesummarisedasafasteraccessibilityofthe
motorunitsandmoreeffectiveexecutionofthemuscle
contraction.Thisisachievedthrough:
1. Improvedsynchronizationoftheimpulses
2.Improvedco-contractionofthesynergists
3. Inhibitionoftheantagonists
4.Recruitingnumberofmotorunits
5.Recruitingtypesofmotorunits.

BloodCirculation

InWBVtraining,dependingontheselectedfrequency,
muscles(andthereforecapillaries)contractthirtytofty

Thisoptimisationofbloodcirculationcouldbeextremely

However,ifcustomaryboneloadingisdecreased,or

Toavoidlowbonemineraldensityinoldage,itis

thepossibilityofpainortightnessifleftuntreated.
IncreasedHormoneProduction
InWBVtraining,thebodyisstimulatedtoproduce
increasedquantitiesofGrowthHormones(GH),Insulin-
likeGrowthFactor-I(IGF-I)andTestosteroneinavery
shortspaceoftime(eightto12minutes).Thereisalsoa
dramaticdecreaseinCortisol,thestresshormone,aswell
asanincreaseintheproductionofNeurotransmittersand
EndorphinssuchasSerotoninandNeurotrophin.These

aconventional,intensepowertrainingsession.
DuetothedecreaseinCortisollevels,thishormonal

eitherageneralstressreaction,oraresponsethatis
commonforhigh-intensityexercise.

Fig. 1.
Change in bone mineral density in the hip after 24 weeks
of Power-Plate training compared to conventional strength
training and the untrained control group.
The Power-Plate group trained 3 times per week,
maximum 30 minutes per session, containing stat-
ic and dynamic exercises for the upper leg and hip
area, such as squats (the movement that allows
you to sit down in a chair) and lunges.
The conventional weight training group trained
3 times per week, about one hour per session,
including a separate warm-up and cool-down.
The control group did no training.

Study Conclusions:
Power-Plate training leads to a significant (1.5%)
increase in hip area bone density, also muscle
strength and postural control increases in post-
menopausal women.
These research findings present an exciting solution
for an ever-worsening problem in our aging popula-tion: osteoporosis, loss of postural control and bal-
ance, bone fractures from falls, and difficult and in-
complete recovery from traumatic falls.
As the average age of the worlds population increas-
es, we are faced with the increasing epidemic of oste-
oporosis. Each year in the U.S. more than 1.5 million
people suffer from fractures due to early bone loss.
One in three women and one in eight men will suffer
from osteoporosis this year. In the U.S., 2.8 million
men and women suffer from bone loss, 1 million have
been diagnosed, while 1.8 million arent even aware
that they are losing integrity in the remodeling of their
bones.
Initial studies on Power-Plate training showed increas-
es in strength in test subjects. The Power-Plate causes
the bodys muscles to contract subconsciously at 30x
to 50x per second, which can stimulate a power train-
ing effect while simply standing on the plate.
Three groups were studied:
The 90 participants - postmenopausal women ranging
in age from 58 to 70 were divided in three research
groups.

Research study shows that exercising on the Power-Plate may be the answer to
osteoporosis: Power-Plate increases bone mineral density, improves strength, power
and encourages fat loss in postmenopausal women.

Fig. 2.
Change in dynamic (fig. 2a) and isometric (fig. 2b) strength in upper leg muscles for the Power-Plate group, the conventional training
group, and the control group.
The Power-Plates low-strain, comfortable, safe, short-duration protocols may allow all popula-
tions to achieve strength and power training effects by just standing on the vibrating plate. In
less than 30 minutes, three times per week, patients and exercisers can achieve strength, fat
loss, better balance and reflexes, improved bone density and ultimately, greater health.
The Results:
The Power-Plate group got positive results: strength
increased as much as 16% in upper leg muscles,
while bone density at the hip increased 1.5%. And,
as a bonus, the Power-Plate group showed an im-
provement in postural control and balance, they in-
creased their muscle strength and lean mass while
they lost body fat and fat mass.
The conventionally trained subjects were able to
slow bone loss, which is consistent with publishedstudies on weight training and bone loss.
The control group subjects continued to lose bone
mineral density at the average rate.
How the Power-Plate was used:
The Power-Plate group performed workouts in 30
minutes or less, including static (still) and dynamic
(moving) exercises for the upper leg and hip area.
The Power-Plate training variables started at the
lowest (easiest) levels, and progressed with:
* increased duration (exercise time)
* increased number of exercises performed
* shortened rest periods between exercises
* increased frequency from 35Hz to 40Hz
* increased amplitude from low to high
The conventional weight training group performed
conventional weight training for a total of one hour
per session, including a separate warm-up and cool-
down.
Conclusion:
The Power-Plate training:
* increases bone mineral density
* is a viable solution to reverse bone loss and to elimi-
nate osteoporosis
* is an accessible training tool to help many popula-
tions prevent falls and fractures
* increases strength
* improves balance and equilibrium
* improves posture
* allows fat loss
* improves health

Study Conclusions:
The Power-Plate increases strength at least
as effectively as conventional resistance
training.
Proof that the Power-Plates strength in-
creases are not due to the placebo effect.
The Power-Plate enhances the bodys sensory
awareness and function, force production and
vertical jump height (a measure of power).
The studys previously untrained subjects
found the Power-Plate workouts to create noadverse side effects. They found the work-
outs were enjoyable and not exhausting.
The positive results suggest the indication
of Power-Plate training for therapeutic uses
with populations who may not be able to per-
form or are not attracted to strength training.
This may provide safe, proactive, effective in-
terventions to enhance wellness in many en-
vironments.
These research findings reveal exceptionally positive
outcomes for many populations who wish to enhance
their strength for activities of daily living. Benefits
of Power-Plates training are not exclusive to healthy
untrained subjects, like those studied here. Benefits
can be seen by anyone who wants to become or re-
main strong and perform better in life. Many popula-
tions such as geriatric, post-injury, rehabilitation, and
performance athletes will benefit from the simple,
effective exercises performed while standing on the
Power-Plate.
Four groups were studied:
Sixty-seven untrained subjects were divided into four
groups, and exercised three times per week for 12
weeks.

lunges and squats (see pictures)
The placebo group also used the Power-Plate, on
a setting that did not generate vertical sinusoidal
vibration. They felt a vibration, but it was too

This research suggests that Power-Plate has great potential in therapeutic environments whereit can enhance muscle performance in rehabilitation patients and in the elderly, and in populations
who may not be able to perform or be attracted to strength training. The Power-Plate can also en-
hance performance of athletes, as suggested by improved strength and vertical jump height.

subtle to elicit a training effect. They performedthe same exercises as the Power-Plate group.
The resistance training group performed a car-
dio warm-up and knee extensor exercises on
two conventional strength training machines.
The control group did not participate in a trai-
ning program.
Tests: The contractile properties of the knee ex-
tensors were evaluated at the start (pretest) and
after 12 weeks (posttest). A dynamometer was
used both pretest and posttest to measure isomet-
ric, dynamic and ballistic knee extensor strength
on all subjects.
The Results:
The Power-Plate group achieved a 16.6% gain
in isometric strength of knee extensors, a 9% in-
crease in dynamic strength of the quadriceps mus-
cles, and a 7.6% increase in vertical jump height.
There were no reports of adverse side effects.
Most subjects found the vibration loading as enjoy-
able and fatiguing, but did not consider it a hard or
exhausting workout.
The placebo group, using a placebo Power-Plate,
did not achieve strength or power gains; they per-
formed the same standing knee extensor exercises
on a Power-Plate that created no vertical vibration
loading.
The resistance training group achieved strength
gains of 14.4% in isometric and 7.0% dynamic
strength were achieved, while there was no improve-
ment in power and vertical jump height.
The control group did not increase in any of the
measurements.
Conclusions:
Training on the Power-Plate has proven to be an ef-
ficient training stimulus to increase muscle strength.
In addition, it is likely that while Power-Plates Whole
Body Vibration requires little exertion and is enjoy-
able, it elicits a biological adaptation that is similar to
that produced by resistance and explosive strength
training.
The Power-Plate provides all the benefits of strength
and power training, without the dangers of heavy
loading, particularly for special populations who
would not tolerate loading but will benefit from
strength gains. The Power-Plate may be indicated
for use in all strength training environments, and for
varied populations.
