评价全身振动对脂肪、骨、瘦素和肌肉质量的影响。将30只7月龄雌性344 Fischer大鼠按体重随机分为三组（基线、振动或对照;每组n=7-10）。将振动组中的大鼠置于连接到Pneumex-Vibe振动平台（Pneumex，沙点，ID，USA）的单独隔室中，并以30-50 Hz（6 mm峰间）振动，每天30 min，每周5天，持续12周。振动干预包括6个5分钟周期，周期之间休息1分钟。全身振动组与对照组的身体成分存在显着差异。全身振动组的体重大约减少10%（平均值±标准差; 207 ± 10 vs 222 ± 15 g，P<0.03），体脂含量较低（20.8 ± 3.8 vs 26.8 ± 5.9 g，P<0.05），体脂百分比较低（10.2 ± 1.7 vs 12 ± 2.0%，P<0.05），血清瘦素水平（1.06 ± 0.45 vs 2.27 ± 0.57 ng ml−1，P<0.01）低于年龄匹配的对照组。总瘦体重、骨矿物质含量（BMC）、骨矿物质密度（BMD）、胰岛素样生长因子-I（IGF-I）或比目鱼肌（SOL）和趾长伸肌（EDL）质量或功能无差异。腰椎（L1-4）的区域高分辨率双能X线吸收测量扫描显示，全身振动组的BMC（0.33 ± 0.05 vs 0.26 ± 0.03 g，P<0.01）和BMD（0.21 ± 0.01 vs 0.19 ± 0.01 gcm−2，P<0.01）显著高于对照组。在摄食量方面未观察到组间差异。这些研究结果表明，全身振动减少体内脂肪积累和血清瘦素，而不影响全身BMC，BMD或瘦体重。然而，椎体BMC和BMD的增加表明振动可能导致局部骨量和密度增加。此外，全身振动不会影响肌肉功能或食物消耗。
To evaluate the effects of whole-body vibration on fat, bone, leptin and muscle mass. Thirty 7-month-old female 344 Fischer rats were randomized by weight into three groups (baseline, vibration or control; n=7–10 per group). Rats in the vibration group were placed inside individual compartments attached to a Pneu-Vibe vibration platform (Pneumex, Sandpoint, ID, USA) and vibrated at 30–50 Hz (6mm peak to peak) for 30 min per day, 5 days per week, for 12 weeks. The vibration intervention consisted of six 5-min cycles with a 1-min break between cycles. There were significant body composition differences between the whole-body vibration and the control groups. The whole-body vibration group weighed approximately 10% less (mean ± s.d.; 207 ± 10 vs 222 ± 15 g, P<0.03) and had less body fat (20.8 ± 3.8 vs 26.8 ± 5.9 g, P<0.05), a lower percentage of body fat (10.2 ± 1.7 vs 12 ± 2.0%, P<0.05), and lower serum leptin levels (1.06 ± 0.45 vs 2.27 ± 0.57 ng ml−1, P<0.01) than the age-matched controls. No differences were observed for total lean mass, bone mineral content (BMC), bone mineral density (BMD), insulin-like growth factor-I (IGF-I) or soleus (SOL) and extensor digitorum longus (EDL) mass or function. Regional high-resolution dual-energy X-ray absoptiometry scans of the lumbar spine (L1-4) revealed that the whole-body vibration group had significantly greater BMC (0.33 ± 0.05 vs 0.26 ± 0.03 g, P<0.01) and BMD (0.21 ± 0.01 vs 0.19 ± 0.01 gcm−2, P<0.01) than the control group. No differences between the groups were observed in the amount of food consumed. These findings show that whole-body vibration reduced body fat accumulation and serum leptin without affecting whole body BMC, BMD or lean mass. However, the increase in vertebral BMC and BMD suggests that vibration may have resulted in local increases in bone mass and density. Also, whole-body vibration did not affect muscle function or food consumption.
