Abstract

INTRODUCTION:

This study determined the effects of whole-body vibration (WBV) and high-impact exercises on postmenopausal women.

MATERIALS AND METHODS:

In this randomized controlled 6-month interventional trial, 58 eligible postmenopausal women were assigned to WBV training group, high-impact training group, or control group. Bone mineral density (BMD) of the lumbar spine and femur were measured by dual-energy X-ray absorptiometry. Additionally, the serum osteocalcin (OC) and C-terminal telopeptide of type I collagen levels were also measured. The functional mobility was assessed using the Timed Up and Go (TUG) test, and fall index was measured using static posturography. The health-related quality of life (HRQoL) and depressive symptoms were assessed using the Quality of Life Questionnaire of the European Foundation for Osteoporosis and Beck Depression Inventory, respectively.

RESULTS:

The BMD at the femoral neck (p = 0.003) and L2-L4 (p = 0.005) regions increased significantly in the WBV group compared to the control group. However, in the high-impact exercise group there were no significant effects on the lumbar spine and femoral neck. The serum OC decreased significantly in the WBV group and increased significantly in both the high-impact exercise and control groups (p < 0.001). The TUG scores decreased significantly in both training groups compared to the control group (p < 0.05). Finally, in both exercise groups, HRQoL and depressive symptoms improved (p < 0.001).

CONCLUSIONS:

Our data suggest that the WBV can prevent bone loss in postmenopausal women. These findings also indicate that WBV and high-impact training programs improve functional mobility, HRQoL and depressive symptoms in postmenopausal women.
