Effect of 8 months of whole-body vibration training on quality of life in elderly women.

Whole-body vibration (WBV) training in elderly may improve muscle strength, muscle power and postural control. However, knowledge about the effect of WBV training in elderly on measures of health as a multidimensional construct (health-related quality of life, HRQoL) is scarce. The present study aimed to determine the effects of WBV training on HRQoL in elderly women. A total of 37 women (aged 82.4 ± 5.7 years) were recruited and were assigned to either the WBV group or to the control (CON) group. After 8 months of training, the WBV group showed non-significant changes on HRQoL and additional health-related outcomes (fall risk, life satisfaction or cognitive status). Our findings are in disagreement with previous studies of shorter duration (6 weeks), which reported positive significant changes in HRQoL in elderly people. Discrepancies among studies may be partly attributed to methodological differences, but the existence of publication bias in previous studies cannot be discarded.
