Whole Body Vibrations Systems Exercise Research News

[Guest guest]

While running and jumping are some of the best ways to maintain or

improve bone strength and help prevent fractures, they aren't the

safest activities for the frail, elderly or physically impaired.

Dr Belinda Beck, senior lecturer at Griffith University's School of

Physiotherapy and Exercise Science, said there was some evidence

that low intensity loading performed at a sufficiently high

frequency may also improve bone mass.

She has recently received funding to test the effects of a whole

body vibration device -- a platform that participants stand on while

it vibrates at up to 30 cycles per second. " Bone generally responds

to exercise that is high intensity but older people can't do that

without the risk of hurting themselves. We need a stimulus that is

effective on bone but does not cause damage. "

Dr Beck said the device was originally designed to enhance muscle

strength in athletes as the vibration forces muscles to contract

more. It was also likely to help improve balance.

" Whole body vibration offers an opportunity to improve bone

strength, muscle strength and balance -- three of the known risk

factors for hip fractures in the elderly. " The vibration device will

be installed in a retirement village on the Gold Coast, providing

easy access for women over 65 years of age who choose to participate

in the study.

Osteoporosis-related fractures are most common in older women,

particularly those with other risk factors such as low body weight,

a history of low calcium intake, and little or no physical activity.

" This is a simple, low intensity alternative that is perfect for

people who can't do more strenuous physical activity, " Dr Beck said.
