摘　　要：目的:研究全身振动对绝经后肥胖妇女肌力及抗骨折能力的影响。方法:100名绝经后妇女,体重指数≥23,随机分为对照组及治疗组。治疗组进行每周3次,每次10min,30Hz,低量2.0m/s的振动。12周后,双能X光骨密度仪扫描第2～4腰椎、左侧股骨颈骨密度;运动功能分析仪检测双下肢肌肉含量,双下肢肌肉力量,股骨颈抗骨折能力。结果:96名妇女完成了12周的试验。治疗组L_2～L_4骨密度上升62.96%,骨量获益0.65%;对照组骨密度上升26.83%,骨量丢失0.89%,差异有显著性(P<0.05)。治疗组及对照组左侧股骨颈骨密度上升率及骨量获益分别为72.22%、1.62%,19.51%、-1.38%,两组差异有显著性(P<0.05)。左腿肌肉力量治疗组及对照组上升率及肌力获益分别为83.33%、12.14%,29.27%、-8.15%,两组差异有显著性(P<0.05)。两组左侧股骨颈抗骨折能力上升率及抗骨折能力获益分别为83.33%、2.65%,19.51%、-1.52%,治疗组明显上升,差异有显著性(P<0.05)。结论:低量高频率全身振动能有效阻止绝经后肥胖妇女的骨量丢失,明显提高肌力,增加抗骨折能力。Objective：To study the effects of whole body vibration（WBV） on resistance fracture after postmenopausal obesity women. Methods：A 12-weeks prospective and randominzed trial of 100 postmenopausal women with body mass index（BMI）≥23.The subjects were exposed to three 10-minutes treaments/week,low-magnitude（2.0m/s） and 30Hz vertical accelerations. Dual-energy X-ray absorpfiometry（DXA） was used to measure bone mineral density（BMD） at the L2-L4 and the neck of left femur at baseline after 12weeks. Mobility Evaluation System was measured the mass and force of tousle in lower limbs and the force of resistance fracture in femoralneck after 12weeks intervention. Results：Ninty-six women completed the 12-weeks trial. BMD of treatment subjects increased 62.96% with a gain 0.65% in the L2-L4,whereas,contral group was increase 26.83% with a loss 0.89%.In the femoralneck,the 72.22% increase observed in the vibration group,central group was increase 19.51%,the benefit were 1.62% and -1.38% in two groups.The left tousle force exhibited a increase 83.33%with benefit of 12.14% in treament group and little increase 29.27% with loss of -8.15% in non- vibration group.The resistance fracture of force of femoralneck was significantly increase in the mechanical group,the increase and gain rate were 83.33%,2.65%,19.51% and -1.52%. Conclusion：WBV of low-level and high-frequency may be effecies for inhibiting the decline in BMD after postmenopausal obesity women,in addition,the tousle force in lower limbs and the force of resistance fracture were significantly increase.
