title: Effects of eight months of whole body vibration training on hip bone mass in older women.
abstract: OBJECTIVE
  the aim of this study was to examine the effect of 8 months of whole-body vibration training on bone mass in octogenarian women.
  
  
  METHODS
  Thirty-seven women (aged 82.4 [SD=5.7] years) voluntarily participated in this study. The vibration group (n=19) trained on a vibration platform twice a week (20 Hz and 2 mm) whereas controls (n=18) did not participate in any training program. Bone mass was measured by dual-energy X-ray absorptiometry at the hip region. General linear repeated measures ANOVA (group by time) was used to examine the effect of whole body vibration on bone mass changes.
  
  
  RESULTS
  After the intervention, in all the hip regions (total hip, femoral neck, trochanter, intertrochanter, Ward's area), no statistically significant changes in bone mass were found.
  
  
  CONCLUSIONS
  eight months of whole body vibration training (twice a week) in elderly women do not produce osteogenic effects.
