| The whole- body vibration workout |
| Standing or working out on the vibration
exercise machines sets off what's known as a "tonic vibration reflex," causing
muscles to react. "Simply by standing on a vibrating plate, it actually causes
your muscles to contract," says Jeff McBride, an associate professor in
biomechanics at North Carolina's Appalachian State University, who has
researched vibration. |

It looks like a big scale, with a pole and handles similar to those found on
some treadmills. Athletes can hang onto the handles and do a variety of
exercises while it vibrates 30-50 times a second, depending on how it's set.
Typically, one schedules 10-minute sessions about three times a week, according
to Susan Hardy, owner of the Midvale Athletic Club, where this vibration exercise machine is
located.
It's not disruptive, but there's a mild sense of instability. The body seems
to respond automatically to try to correct it. And that's the magic, proponents
say. On a basic, neural level, all the big and little muscles work to counter
the vibration.
Barlow is Hardy's mother. And though she's not the reason Hardy got the
device, both mother and daughter are convinced it may change Barlow's life.
Davis says it's reduced swelling in Barlow's legs and overall water retention
already.
Besides multiple sclerosis, the device boasts a track record for helping those
who normally wouldn't exercise much -- people with arthritis, Parkinson's
disease, stroke survivors and others -- get some of the benefits of exercise.
It's also touted for people with osteoporosis, a condition in which bone density
is lost, or as a prevention for it. Whole-body vibration increases growth
hormone levels significantly, according to studies. |

The theory behind whole-body vibration benefiting athletes came out of Russia
in the 1970s. Trainers chasing Olympic gold said it worked, which led to
research by the Russian space program. Now NASA is reportedly doing its own
research with the vibrating machine because space travel and its zero-gravity
conditions seems to degenerate bone and muscle mass, which both rely on
weight-bearing activity to maintain them.
It further claims that "100 percent of the muscle fibers contract," leading
to a host of benefits. It's currently quite popular in Europe and is slowly
picking up steam in the United States.
The athletic club installed the vibration plate about four months ago. What
struck Hardy when she began to use it was the increase in her energy level. She
was pleasantly surprised that her workout on the machine left her a little sore,
just like a beneficial, more traditional workout.
She talks about the 60-something man who stands on cement floors all day. He
said the Power Plate makes his legs and feet feel better. Or the woman who'd
lost a fair amount of weight, then stopped losing. The addition of vibration fitness machine
to her workout helped, she says. She's using the vibrating exercise machine for the third time, hoping it will jump-start weight
loss that has stalled a bit. The stay-at-home mom laughs that "you can literally
feel it at the end of your hair."
