G Force Comparison on different machines:
I talk a lot about Pop G force versus Push G force. This all has to do with how the G force is displaced in the acceleration of the plate. When you feel the different plates, you instantly can feel how a Zaaz or a Hypervibe has that split second pop while the Vmax Pulser Pulser or Vibra-Trim VT500 has a more fluid G force.
The equation for calculating this G Force when I asked an engineer is for the Zaaz 20K machine was
G-force exerted on an object experiencing sinusoidal movement, such as an oscillating plate
Extrapolated, the max G-force of a vibration machine at 10mm displacement (amplitude), at a frequency of 15.5Hz can be found with:
1+(.010/9.8)[(2*Pi*7.75)]^2 = 3.4g
The ZAAZ 20K at the highest speed has 3.4 G forces which is no where near the 17 G forces that Hypervibe has.
Note: Beware of companies saying they have double the G force than the vibration machine really has. If a machine has 5 G force they can go by both sides going up and double it to 10G. The Hypervibe actually has 17 G forces on each side. When companies say there machine goes to 28 hertz, they might be referring to a machine that goes 14 hertz on each side. The Hypervibe goes to 28 hertz on each side.
Basically, if people want to get high G forces for high intensity workouts, I would use the Hypervibe. If someone has a bad back and wants a machine that takes out most of the ballistic impact even at the high speeds, then the Zaaz is the least ballistic impact pivotal machine I've been on.
See my Zaaz page for my full review on this machine.
Note: with heavier people, if the amperage is not high enough, the pop feeling goes away and turns into more of a push. Some people prefer this push while others need the pop, especially when leaning on their heels. Leaning on your heels makes a machine bogs down is when you know the machine can't take its maximum "loaded" G force and the G force they have on the manufacturer's website is measured unloaded with no weight on the plate. This is not fair to the consumer and it confuses all my customers.
The closer you stand towards the tippy edge of the plate the more push feel. If the machine is on its low setting at 5 hertz when doing a lymphatic cleanse, standing on a shorter plate like a Hypervibe has a more pop while the 27 inch plate of the Vmax Pulser has more of that push. Before buying a machine it is good to know the difference so you get the right machine.
Warning: not everyone is in a good enough physical condition to handle a high G force machine over 14 hertz. This depends on someone's bone density, their ability to process lymphatic waste, and mostly if their back or knees are bad.
Note: Input wattage is not the same as output wattage. Many vibration machines are rated at 1000 Watts. This almost 95% of the time when a machine is really cheap only input wattage. The Zaaz 20K is rated at 400 Watts. The Vmax Pulser is rated at 1100 Watts on their pivotal motor. When you try the difference it's easy to know which machines are rated at input versus output wattage.
To get the "pop" feel with maximum G force, the vibration machine must be on a hard floor. The hard floor prevents the wiggle room that a carpet gives. That extra few milimeters of cushioning in the carpet can absorb the power and the floor will absorb the G force instead of the plate.
The decision to make is how much smooth you want the vibration and how much of a ballistic impact you want to travel up the spine when when standing on your heels. The more powerful the machine is, the stronger the lymphatic flushes will be and the more impact it will have on the bones.
