These vibration machines allow you to exercise vertically on a vibrating platform (the
intensity can be adjusted to suit). The theory is that when the body senses
instability (in this case the vibration) the muscles involuntarily contract and
stretch to compensate.
People who use these special vibrating platforms while lifting weights
are able to "strengthen and tone" as well -- if not better --
than traditional strength training "in just 10 minutes a day, three days a
week," according to the companies that promote vibration equipment. Vibrating equipment ranges from $10,000 for equipment like VibroGym made in Europe
to $1699 for the VibraSlim Whole Body Vibration Platform from the USA.
WBV is low-impact, which makes it particularly good for older or obese people
who find traditional strength training difficult. The most encouraging research
studies have found WBV to be effective in increasing bone mineral density in
post-menopausal women. Since women in this group are particularly susceptible to
osteoporosis, this is exciting news.
"The bone benefits are established," says Dr. Aurelia Nattiv, a professor of
sports medicine and team physician at University of California, Los Angeles.
Other research is equally positive, finding vibration training is an
effective nonpharmaceutical form of therapy that eases pain in the lower back,
helps stroke victims and could lead to greater improvements in the circulation
system than conventional therapies. It might help lower blood pressure, too. |
