I work in a gym which has recently purchased a Life Fitness - Power Plate. Today we had a training seminar with a Power Plate rep. It was fairly interesting to be honest. But one slide in the show, grated.
According the rep. Using the Power Plate is more effective than doing a regular squat… I could feel my blood pressure rising at this point ! I have a strong gut feeling that this is crap. But I couldn’t think on the spot of a decent argument against her example.
The argument she presented was that Joe Bloggs weighing 70kgs squatting 70kgs was working less than Ms Bloggs on the Power Plate.
Where is the flaw in this argument ? Should time be a factor ? I was thinking that if Joe Bloggs did ten reps then would he use 1,373.4 newtons x 10 = more than the Power Plate user over a given period of time ? Squatting has to be better, surely ? Can anyone help me find the flaws in this example.
Bullshit!
This is isometrics with a vibrator, correct?
F=m*a, true. but they are misleading you by saying that it is somehow better because of this. First of all, you are not doing work since you don’t apply force to a mass over some distance (as in the squat).
That piece of junk has you traveling some distance but it is only at most the amplitude of the vibrations. The acceleration is probably so high and the waves so small, that you do not move the whole amplitude of the vibration.
The worst part is that they are cherry picking the data to polish that turd. They use peak acceleration on their device and assume squats are isometric, which is dishonest.
To sum it up, that slide is making poor assumptions in order to promote the product.

Thanks for explaining that clearly. The squat 'vs Power Plate example we had certainly was flawed.
