XG10 the 12G Force Plate from the DKN Xseries - Introduction
[ NOTE: Please forgive my English. I am Italian and I try my best to write in English, so if you find weird sentences, please report.]
Outstanding. First, for the 12 G that represents an exeptional and revolutionary goal for a vibration training Plate on this price level, and second, for the great quality gap that DKN was able to develop in short time. The release of the previous PRO Evolve model was in late february 2008. If we compare the XG 10 price to other Plates actually on the market, capable of the same performance, we can see the XG10 is sold at half of the competitors' prices.
I saw the prototypes of the XG10 and the XG5.0 just 4 months ago (end ofJune 2008) and I can't explain how DKN developed a so masterly finished Plate, impeccable even in secondary aspects, such the packaging or the constructive details. No visible welding, a new engine, everything in steel and a series of constructive solutions totally new to the DKN standard concepts. With the XG10 release DKN enters with a honorable mention in the top class of the professional Vibration Training Plates .

Handle bar and control unit
The handlebar is the only element that recalls the formerly released Pro Evolve shape. Solid and ergonomic, comfortable. Control panel has changed the skin: very large display and user friendly buttons. Selecting the programs or the time and frequency is easyer than ever. Intresting new detail is the lower control unit.
The vibrating platform
Totally revised and completely re-designed. 42 x 85 cm, 16,5 x 33,5 in. Height from ground 16,5 cm or 6,5 in, actually the shortest! Pure carbon steel, rubber top. Floats on spring joints, and the springs are the only DKN typical solution. Maximum load is 150 Kg or 330 lbs.
Stepping up it sinks a bit, however it is very stable. The stabilizer works fine when you lean back in the deep squat.
XG10 Engine
The XG10 engine is firmly fixed to the vibrating platform, in the lower middle of it. Continuous current powered, it provides a strong vibration. 15G unloaded at 45Hz, reducing to 11G with 90kg 198lbs load.
The engine is totally silent, incredibly silent. As always we won't talk about the power of the engine in Horses or Watts because it is not a useful comparison factor. See the acceleration in the next paragraphs for a comprehensive explanation.
XG10 Noise
As told above the XG10 is a very silent vibration Training Plate. We affirm with no doubt that the XG10 has the silent record ever. Listen to the XG10 noise to verify the minimum sound level it produces. Less the noise equals less vibration transmission to the floor and neighborhoods.
XG10 acceleration and G force
G force or Acceleration is the measure unit of vibration intensity or vibration strength. Engine power means nothing. Engine power is not a valid parameter to define the vibration strength a Plate can produce. There is no uniformity within declared power and produced vibration because depends from too many factors. The weight of the eccentrics, the way the joints are made, are all strong misleading factors. Some Plates with 500W engines result in much more vibration intensity than others with declared power of 1200W.
We started to clear up this since 2006, when all the manufacturers were listing the engine power only. Now they are publishing the G force, also.
The vertical magnitude under all circumstances is what matters.
Acceleration is measured in m/s2 or in G force. 1G = 9,80665 m/s2
Z (vertical up down) light blue
X (horizontal back forth) yellow
Y (horizontal left right) magenta
Max Acceleration with 90kg 198 lbs load: 11,2 G o 110 m/s2 - Frequency: 45Hz
The above is the measure of the maximum strength vibration at 45Hz, with a load (me) of 198 lbs or 90 kg. Unloaded the XG10 produces 13 to 15G. We use a very sensitive tri-axial professional accelerometer.
Some vibration training Plates dysplay a frequency ratio that may differ from the real frequency. In this case the XG10 does not differ.
45Hz on the display are effective. If you count the repetitions in one second (in the range from 1000 to 0 milliseconds) you can verify.
The table here below reports all the values measured with the accelerometer. Links open the waveform images. We measured the vibration at the lumbar zone in a correct posture with knees bent (OK) and in a wrong posture with no knee bend (ERR).
| 90kg | 00kg | lumbar zone OK | lumbar zone ERR | head OK | head ERR | |
| 20Hz | 0,9 | 1 | ||||
| 30Hz | 2,4 | 2 | ||||
| 35Hz | 3 | 2,8 | 0,3 | 1,5 | 0,2 | 0,7 |
| 40Hz | 5 | 4 | ||||
| 45Hz | 11,2 | 15 | ||||
| 50Hz | 8,7 | 8,5 |
Here below the G force chart at the whole frequency range of the XG10.
EMG - muscular activity of the XG10

|
vibration off |
vibration on |
In the image the activity of the right leg muscles measured with EMG electromiography. On the left in the graph the reaction of the muscle without vibration and on the right with vibration. I made a deep squat standing in a static position with the knee bent at 90°. First with no vibration, then with vibration. The muscle activity increase, as you may see is twice higher, with the same muscle fatigue and load.
Empiric measure of the XG10 vibrating platform magnitude or vertical excursion
The excursion measured with pencil and paper follows the same values of the accelerometers. You can see at 45Hz the vibration is much more strong than the other frequencies.
This is the most unprecise measure, pencil and paper. It has a mere indicative value, not absolute. In fact if it is done by another person with another XG10 Plate it may differ. Before you can get good results you have to try many times. The point on the platform where we put the pencil was close to the belts holder. We did that with no load on the platform.
XG10 constructive details
The base seen from the bottom. It gives access to the main components: joints, engine and electric Plates. The whole base weight is of 52 kg or 114,5 lbs. There is a 8mm 0,3in thick neoprene surface below the base. The XG10 should be placed on a regular floor.
*** DO NOT DRAG FORCEFULLY THE XG10 ON THE FLOOR, rather lift it, unless you want to tear the neoprene base angles.
The handlebar column is firmly fixed to the base by three screws. The connectors are quite easy to fasten and are very reliable to vibration.
The XG10 electricity power plug. In the image you can see the European version. US has different voltage. The machine works both with US and EU voltage.

XG10 Accessories
XG10 comes with Instruction Manual and Vibration Training manual. There is the Exercises Manual Vol.1, an excercise poster, an interactive DVD, belts, dampening mattress.
XG10 pre-installed programs
Five options for the main body muscle groups training: abdominals, whole body, upper body, lower body and manual settings. Every step of the scheduled exercises comes with an image to show you the right posture, time and frequency to use. The programs are very useful for the very first month. After the initial accustomization you will begin to use the "manual" settings, following the plans on the Exercise Manual. So the figures and the programs will be left for a more advanced training. I personally believe that the most important details on a Vibration Training Plate control unit are the Manual Settings. The XG10 manual controls are perfect, intuitive and easy and you don't bother with touch screen buttons. You have control on time, from 0 to 10 minutes with steps of 30 seconds, on frequency from 20 to 50 Hz with steps of 1 Hz. Start, stop, repeat. Very useful the lower unit, when you perform "ground" exercises.
XG10 Assembly instructions
Go through the step by step assembly sequence of the XG10. Time required for the first time assembly: 15 minutes. Assembly tools are all included except a screw driver for the control unit screws.
