Decreased bone mineral density (BMD) is a common condition in postmenopausal women that can be managed with impact activities. Among the activities studied are the whole-body vibration (WBV) and muscle-strengthening exercises. The purpose of this study was to compare the effects of WBV versus Pilates exercise on BMD in postmenopausal women.
In this study, 51 postmenopausal women were randomized into 3 groups: vibration (n = 17), Pilates (n = 17), and control (n = 17). Outcomes were the areal bone mineral density (aBMD) (lumbar spine, femoral neck, total hip, trochanter, intertrochanter, and ward's area) assessed by dual-energy x-ray absorptiometry at baseline and follow-up. The interventions were performed 3 times a week for 6 months, totaling 78 sessions. The analysis was performed with intention-to-treat and covariance analyses adjusted for baseline outcomes.
After 6 months, 96.1% of the participants completed the follow-up. The analyses demonstrated significant mean between-group differences in favor of the interventions: vibration versus control, for the aBMD of the lumbar spine (0.014 g/cm; 95% confidence interval [CI], 0.006-0.022; P = .018, d = 1.21) and trochanter (0.018 g/cm; 95% CI, 0.006-0.030; P = .012, d = 1.03); and Pilates versus control, for the aBMD of the lumbar spine (0.016 g/cm; 95% CI, 0.007-0.025; P = .008, d = 1.15) and trochanter (0.020 g/cm; 95% CI, 0.010-0.031; P = .005, d = 1.28).
In postmenopausal women, 3 weekly sessions of WBV or Pilates administered for 6 months provided an equal effect on BMD.
骨密度降低(BMD)是绝经后妇女的常见病症,可以通过冲击性活动来进行治疗。在这些活动中,全身振动(WBV)和肌肉强化运动受到了研究。本研究的目的是比较 WBV 与普拉提运动对绝经后妇女 BMD 的影响。
本研究将 51 名绝经后妇女随机分为 3 组:振动组(n = 17)、普拉提组(n = 17)和对照组(n = 17)。通过双能 X 射线吸收法在基线和随访时评估骨密度(BMD),结果为腰椎、股骨颈、总髋、转子间、转子间区和 wards 区的面积骨密度(aBMD)。干预措施每周进行 3 次,持续 6 个月,共进行 78 次。分析采用意向治疗和协方差分析,根据基线结果进行调整。
6 个月后,96.1%的参与者完成了随访。分析显示,干预组之间存在显著的平均组间差异,有利于干预:振动组与对照组相比,腰椎 aBMD (0.014g/cm;95%置信区间[CI],0.006-0.022;P =.018,d = 1.21)和转子间区 aBMD(0.018g/cm;95%CI,0.006-0.030;P =.012,d = 1.03);普拉提组与对照组相比,腰椎 aBMD(0.016g/cm;95%CI,0.007-0.025;P =.008,d = 1.15)和转子间区 aBMD(0.020g/cm;95%CI,0.010-0.031;P =.005,d = 1.28)。
在绝经后妇女中,每周 3 次全身振动或普拉提运动,持续 6 个月,对 BMD 的影响相同。
