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

這是一千個深夜廣告節目之星：震動平臺--只用站在那裏晃動就能保證所有艱苦贏得的好處。

While previous research has looked into how whole body vibration (WBV) functions as an 'exercise mimetic', there's still a lot we don't understand about how vibration alone can produce such significant changes in the body.

雖然之前的研究調查了全身振動（WBV）是如何作爲一個“模擬運動”作用的，但我們對於僅振動是如何在身體上產生如此巨大的變化還很不瞭解。

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

現在，對小鼠的最近一項研究說明了WBV在新陳代謝中帶來的健康益處的新方式：通過調整住在你體內和體表的密集微生物菌羣的組成。

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

“雖然來自WBV的生化和生理學改善作爲一項模擬鍛鍊是不容置疑的，但WBV如何達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。”來自奧古斯塔大學的兒科整形外科醫師餘傑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 protects against obesity, insulin resistance, and type 2 diabetes.

爲了研究WBV對新陳代謝的作用，餘醫師和他的團隊研究了患2型糖尿病的老鼠模型：轉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

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

這些動物以及健康對照組每天進行20分鐘的全身振動，持續4周。實驗後，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 macrophage immune cells in the mice.

他們發現全身振動似乎能改變老鼠體內的巨噬免疫細胞的分佈和組成。

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

實驗結果也許能提供研究治療2型糖尿病患者炎症的範本，但是研究人員強調，我們對於其中的有關機制還所知甚少。

You can feel the vibration on the violin string.

你可以感覺到小提琴琴絃的振動。

文中vibration platform，指“震盪減肥儀”。

vibration的動詞原形vibrate，v.（使）振動[顫動]；擺動

The foundation of the city began to rumble and vibrate.

全城的地底都隆隆作響，震動起來。
