Sarcopenia and osteoporosis represent a growing public health problem. We studied the potential benefit of whole body vibration (WBV) training given a conventional or a high dose of daily vitamin D supplementation in improving strength, muscle mass and bone density in postmenopausal women.In a 2 x 2 factorial-design trial 113 institutionalised elderly females aged >70 years (mean age 79.6) were randomly assigned, either to a WBV or a no-training group, receiving either a conventional dose (880 IU/d) or a high dose (1600 IU/d) of vitamin D3. The primary aim was to determine the effects of 6 months of WBV and/or vitamin D supplementation on isometric and dynamic strength, leg muscle mass and hip BMD. Additionally, the increase in 25(OH)D levels between conventional and high dose supplementation was compared.After 6 months of treatment, dynamic muscle strength, hip BMD, and vitamin D serum levels improved significantly in all groups while isometric strength and muscle mass did not change. When compared to no-training, the WBV programme did not result in additional improvements.
When compared to 880 IU, a high dose of 1600 IU of vitamin D did result in higher serum vitamin D levels but did not result in additional improvements.In institutionalised women above 70, the WBV training protocol tested is not more efficient in enhancing muscle mass, strength and hip BMD compared with vitamin D supplementation.
A higher dose of 1600 IU of vitamin D does not provide additional musculoskeletal benefit in this population compared with conventional doses. (c) 2010 American Society for Bone and Mineral Research. DOI: 10.1002/jbmr.181 PMID: 20648661
