You Asked: Power Plate Pros and Cons

You're asking and I'm answering.

Dear Fit,
My gym is getting "Power Plates" installed and I am curious about the benefits of standing on a vibrating platform compared with a one hour workout in the gym? They are claiming it can have the same effect but I am not convinced! Of course, I'm going to try one but how is this beneficial for overall long-term health?

The Power Plate revolution is beginning to fully materialize and I think it is cool that your gym is springing for some fancy new equipment. However, I am with you and am a little incredulous that 10 minutes on a Whole Body Vibration Machine (WBV) can replace a 60 minute traditional workout. To hear the pros and cons of the Power Plate, just read more.

I must begin by stating that I have never tried a Power Plate or any other WBV machine exercise, and although I am skeptical, like you I am also intrigued. A WBV platform vibrates mildly activating muscles to contract 30 to 50 times a second. Cedric Bryant, the chief physiologist with the American Council on Exercise, feels that WBV could be a good supplement to a sensible diet and exercise program. Some small studies have found that performing squats on a WBV machine is slightly more effective at increasing muscle power as well as jump height than performing squats on stable ground. However, with no external load forcing muscles to exert themselves some members of the sports medicine world don't think that vibrations alone could do much good for healthy, young individuals. The benefits of using a vibration machine for people with multiple sclerosis is dramatic, and other research has found that using WBV has inhibited bone density loss in post menopausal women.

Regarding long term health, the major concern is that high-amplitude vibration can be dangerous over time since it sends jarring waves throughout the body. This jarring motion could create low back pain, cartilage damage, blurred vision from retinal tears, hearing loss and even brain damage (gray matter being shaken too hard in the skull). It is not recommended to use the machines for over 30 minutes a day.

One thing is for certain, your core will get worked using a Power Plate. I can't wait to hear what you think of the machines. Be sure to let us all know.

Vibration Workouts: Some Benefit Claims on Shaky Ground

I have never tried a Power Plate, but something about it just reminds me of those vibrating belt machines from the 1950s. You know, where you put the vibrating belt around your bum and it was supposed to jiggle all the fat off.

Basically, there are two major players in vibrational exercise these days, one being the Power Plate, which is a small standing platform that vibrates really fast with a handle (it kind of looks like a floor polisher or a vacuum cleaner on steroids). The other Whole Body Vibration, made by Soloflex, is an over sized vibrating skateboard with no handles. You can pretty much do any move on these machines, from squats to yoga poses, from push-ups to standing hammer curls. The workout is closer to weightlifting than aerobics, like strength, core and balance training all rolled into one.

The list of claimed benefits from this type of workout is rather long: improves flexibility and strength, reduces pain and stress, builds muscle and reverses osteoporosis, but the most praised benefit by far is the decrease in workout time. Getting all shook up while doing alternating lunges really taxes your muscles. NASA is even investigating vibrational strength training as a means of reducing muscle atrophy and bone loss that accompany long trips in space.

However, some researchers are not completely sold on these vibration workouts. The major concern being that high-amplitude vibration can be dangerous over time since it sends jarring waves throughout the body. This jarring motion could create low back pain, cartilage damage, blurred vision from retinal tears, hearing loss and even brain damage (gray matter being shaken too hard in the skull). Soloflex even recommends using the device only 30 minutes a day. More than that and you exceed industry standards for safe vibrations in the workplace. I never thought I would hear OSHA rules applied to fitness machines.

Keeping all this in mind, I still want to try a vibrational work out, do you? Let me know in the comments below.
