Effects of Whole Body Vibration with Load Stimulation in Postmenopausal Women

BACKGROUND: This study aimed to investigate the effect of whole body vibration (WBV) with load stimulation (WBVLS) on body composition, postural balance, leg strength, and bone mineral density (BMD) in postmenopausal women.
MATERIAL AND METHODS: Thirty-four postmenopausal women participated in the study and were randomly divided into a WBVLS group (n=13), a WBV group (n=13), and a control group (n=11). The WBVLS group performed WBV with loaded stimulation for 10–15 minutes per set, 5 times a week, for 12 weeks. The WBV group performed WBV exercises, whereas, the control group received no treatment. Outcome measures included body composition, knee extension strength, postural balance, and BMD of lumbar spine and femoral neck.
RESULTS: Body composition, postural balance, and BMD of the lumbar spine showed significant improvements in the WBVLS group (P<0.05). Leg strength showed significant improvement in the WBVLS and WBV groups (P<0.05) as compared to baseline, but not in the control group.
CONCLUSIONS: WBVLS for postmenopausal women may be beneficial for improving body composition, postural balance, leg strength, and BMD. This study provides effective WBV exercise guidelines for postmenopausal women.
