Changes in balance, functional performance, and fall risk following whole body vibration training and vitamin D supplementation in institutionalized elderly women. A 6 month randomized controlled trial

113 women were randomly assigned to one of four groups. Two groups received 6 months of whole body vibration (WBV) training accompanied with either a conventional or high dose of vitamin D3. Two groups received no training accompanied with either a conventional or high dose of Vitamin D3. Results from this study indicated that that vitamin D supplementation increased walking speed and TUG performance compared to baseline values. WBV demonstrated significant improvements in walking, endurance, and TUG performance.
