振動，并不能減肥

It's the star of a thousand late-night infomercials: vibration platforms that promise all the hard-wonbenefits of exercise while you simply stand there andjiggle.

經(jīng)久不衰的深夜廣告之星：振動儀——只用站在那里晃動，就能達(dá)到辛苦鍛煉同樣的結(jié)果。

While previous research has looked into how wholebody vibration (WBV) functions as an 'exercisemimetic', there's still a lot we don't understandabout how vibration alone can produce suchsignificant changes in the body.

雖然之前的研究調(diào)查了全身振動(WBV)是如何作為一個“模擬運(yùn)動”作用的，但我們對于僅振動是如何在身體上產(chǎn)生如此巨大的變化還很不了解。

Now, a recent study in mice illustrates a new way that WBV could bring about health benefits inthe metabolism: by modifying the makeup of the microbiome, the immense population ofmicrobial organisms that reside in and on your body.

現(xiàn)在，對小鼠的最近一項(xiàng)研究說明了WBV在新陳代謝中帶來的健康益處的新方式：通過調(diào)整住在你體內(nèi)和體表的密集微生物菌群的組成。

"While the biochemical and physiological improvements from WBV as an exercise mimetic areindisputable, how WBV achieves such effects is likely multi-faceted and largely unknown," aresearch team led by paediatric plastic surgeon Jack Yu from Augusta University explains in anew paper.

“雖然來自WBV的生化和生理學(xué)改善作為一項(xiàng)模擬鍛煉是不容置疑的，但WBV如何達(dá)到這樣的效果很可能有多方面原因，在很大程度上是未知的。”來自奧古斯塔大學(xué)的兒科整形外科醫(yī)師余杰克在一篇新論文中解釋說。

To investigate WBV's effects on metabolism, Yu and his team studied a mouse model of type 2 diabetes: mice engineered with a leptin deficiency mutation, lacking a protein that protectsagainst obesity, insulin resistance, and type 2 diabetes.

為了研究WBV對新陳代謝的作用，余醫(yī)師和他的團(tuán)隊(duì)研究了患2型糖尿病的老鼠模型：轉(zhuǎn)基因消瘦素缺陷變異老鼠缺少防止肥胖、胰島素抵抗和2型糖尿病的蛋白質(zhì)。

These animals – along with healthy controls – were subjected to WBV for 20 minutes a day fora period of four weeks. After the experiments, researchers analysed samples of the mice'sabdominal adipose tissues, and also stool samples.

這些動物以及健康對照組每天進(jìn)行20分鐘的全身振動，持續(xù)4周。實(shí)驗(yàn)后，研究人員分析老鼠腹部脂肪組織以及糞便樣本。

What they found was that WBV appeared to alter the distribution and makeup of macrophageimmune cells in the mice.

他們發(fā)現(xiàn)全身振動似乎能改變老鼠體內(nèi)的巨噬免疫細(xì)胞的分布和組成。

The results might offer a promising new lead into research looking at fighting inflammationin human patients with type 2 diabetes, although the researchers emphasise there's still a lotwe don't know about the mechanisms involved here.

實(shí)驗(yàn)結(jié)果也許能提供研究治療2型糖尿病患者炎癥的范本，但是研究人員強(qiáng)調(diào)，我們對于其中的作用機(jī)制還知之甚少。
