A daily dose(1) of whole body vibration(2) may help reduce the usual bone density(3) loss that occurs with age, Medical College of Georgia researchers(4) report.

Twelve weeks of daily, 30-minute sessions in 18-month old male mice(5) -- which equate to(6) 55- to 65-year-old humans -- appear to forestall(7) the expected(8) annual loss that can result in(9) fractures(10), disability(11) and death. Dr. Karl H. Wenger, biomedical engineer(12) in the MCG(13) Schools of Graduate Studies and Medicine, reported the findings with his colleagues(14) in the journal Bone.

Researchers found vibration improved density around the hip joint(15) with a shift toward higher density in the femur(16), the long bone of the leg, as well. Hip fractures(17) are a major cause of disability and death among the elderly.

They also found a reduction in a biomarker(18) that indicates bone breakdown and an increase in the surface area(19) involved in(20) bone formation(21) in the vibrating(22) group.

The findings provide more scientific evidence that the technique, which dates back to(23) the 1800s and is now showing up(24) in homes, gyms and rehabilitation(25) clinics, has bone benefit(26), particularly as a low-risk(27) option for injured individuals with limited mobility(28), Wenger said.

The scientists theorize that(29) the rhythmic(30) movement, which produces a sensation similar to that of a vibrating cell phone(31) but on a larger scale(32), exercises(33) cells(34) so they work better. Vibration prompts(35) movement of the cell nucleus(36), which is suspended(37) by numerous(38) threadlike(39) fibers(40) called filaments(41). “The filaments get all deformed(42) like springs(43) and then they spring back(44),” Wenger said.
