全身震动对大鼠体脂和骨健康的影响Effects of Whole Body Vibration on Body Fat and Bone Health in Rats

摘要(Abstract):
取30只7月龄雌性344Fischer大鼠,按照体重随机分为3组:基本组、震动组和对照组,每组10只大鼠.将震动组大鼠置于震动平台上,每天震动30min,频率为30~50Hz(振幅值6mm),每周5天,共12周.震动分为6个5min间隔进行,间隔时间1min.对三组大鼠脂肪、骨骼、瘦素和肌肉重量进行统计学分析对比.结果表明全身震动降低体脂和血清瘦素,不影响总体矿物质量、密度和瘦体重;但腰椎矿物质量和密度增加,说明震动可增加局部骨量和骨密度.另外,全身震动不影响食物消耗.
