The aim of this study is to determine the effect of a 24-week of vibration training and detraining in postmenopausal women with primary osteoporosis. Fourty volunteer women were randomised into vibration group (VG), strength group (SG) and control group (CON). Bone mineral density (BMD) as primary outcome measure was measured at baseline, at 24th week, and at 48th week. The secondary outcome measures as physical performance, muscle strength, and body composition were collected at baseline, at 4th week, 12th week, at 24th week, and also 48th week. After training, calve and lunge test performances increased significantly, and the lumbar BMD was lower in VG compared with CON. At 48th week lumbar BMD in VG increased compared to CON, while increase in femur BMD was higher in CON. In SG, femur BMD was lower than both VG and CON. This data suggested that vibration training effect differed for the lumbar and femur BMD.
