Overview
Brief Summary
We investigated the effects of whole body vibration (WBV) and high-impact (HI) exercises in postmenopausal women with low bone mineral density. In summary, WBV exercises are effective in preventing bone loss and WBV and HI exercise programs are effective in decreasing fall risk, increasing health-related quality of life and improving depressive symptoms
Detailed Description
Purpose: The aim of this study was to determine the effects of six months of supervised whole-body vibration (WBV) and high-impact (HI) exercises on bone mineral density (BMD), serum bone turnover markers, fall risk, health-related quality of life (HRQoL) and depressive symptoms in postmenopausal women, additionally, to evaluate the advantage of each training program to another. Methods: In a prospective, randomized controlled 6-month interventional trial 58 eligible postmenopausal women were assigned to WBV training group (n=19), HI training group (n=19), or control group (n=20). The patients in both training groups participated in a supervised training program, which consisted of the one-hour exercise session three times a week for six months. The WBV groups received vibration (30-35 Hz, 2-4 mm) in five different static positions. The HI group jumped rope (10-50 jumps/day). All patients received calcium (1000 mg) and vitamin D (880 IU) supplementation per day. In all participants, baseline and six-month BMD at the lumbar spine and femur were measured by Dual-energy X-ray Absorptiometry (DXA). Serum osteocalcin (OC) and C-terminal telopeptide of type I collagen (CTx) were measured at baseline, three- and six-month intervals. Fall risk was assessed by using the Timed Up and Go (TUG) test and fall index measured by static posturography at baseline, three- and six-month intervals. HRQoL and depressive symptoms were assessed using the Quality of Life Questionnaire of the European Foundation for Osteoporosis (QUALEFFO) and Beck Depression Inventory (BDI), respectively, at baseline and six-month of the study.
