| 9 | Athletes and gym rats now pay top dollar for the stuff. | 运动员和健身老鼠现在为这些东西付出了最高的美元. |
| 10 | And whey has been joined by powders made from its fellow dairy product, casein, | 加上乳制品的粉末, |
| 11 | and from leguminous plants, namely peas and soya beans, which is best. | 和来自豆类植物, 即豌豆和大豆, 这是最好的。 |
| 12 | A crucial ingredient to look for is leucine. | 需要寻找的一个关键成分是Leucine。 |
| 13 | This is about 12% of whey powder's mass and one of the 20 amino acids from which proteins are composed. | 这是大约12%的 wh粉质量和20种氨基酸之一,由蛋白质组成. |
| 14 | It is one of the nine dubbed essential because humans cannot make them. | 它是被誉为必不可少的九种方法之一,因为人类无法制造它们. |
| 15 | So they must arrive in food. | 因此,他们必须到达食物。 |
| 16 | 但是Leucine有很多才华 | |
| 17 | It also activates a biochemical pathway called the mechanistic target of rapamycin, or mTOR, | 它还激活了一种生化途径,称为机械目标 rapamycin,或MTOR, |
| 18 | that encourages protein synthesis. | 这鼓励蛋白质合成。 |
| 19 | After exercise, mTOR gets to work replenishing muscle fibers. | 锻炼后,MTOR可以从事补充肌肉纤维的工作. |
| 20 | Leucine thus helps provide not only the signal but also the raw materials. | 因此,Leucine不仅有助于提供信号,而且有助于提供原材料。 |
| 21 | Put another way, says Stuart Phillips, a kinesiologist at McMaster University, | 换句话说,斯图尔特·菲利普斯,麦克马斯特大学的动脉学家 |
| 22 | leucine is both brick and brick layer. | leucine 既是砖层,又是砖层. |
| 23 | In younger active adults, leucine's muscle building might goes only so far, | 在年轻活跃的成年人中,Leucine的肌肉建构可能只进行到现在, |
| 24 | says Brad Schoenfeld of Lehman College in New York. | 纽约雷曼学院的布拉德·朔恩费尔德 |
| 25 | There is no additional benefit to taking more than that found in a standard 25 gram scoop of whey powder. | 吃25克的奶粉没有其他好处 |
| 26 | Older people's muscles are tougher to stimulate. | 老年人的肌肉更硬,可以刺激. |
| 27 | For them, whey with extraleucine can be beneficial for building brawn, | 对他们来说,用外聚氨酯对建设勃朗有好处, |
| 28 | according to a study of 20 people in Nutrition Journal in 2014. | 根据2014年"营养杂志"20人的研究. |
| 29 | The other amino acids are important too. | 其他氨基酸也是很重要的. |
| 30 | Writing in the Journal of Physiology in 2012, | 2012年在"生理学杂志"上写作, |
| 31 | Dr Phillips and his colleagues gave three groups of young men different combinations of whey, | 菲利普斯博士和他的同事 给了三组年轻人不同的组合 |
| 32 | leucine and other amino acids immediately after a leg workout. | leucine和其他氨基酸在腿部运动后立即出现. |
| 33 | Some took full whey, for example, whereas others had a quarter dose topped up with extraleucine. | 例如,有的服用了全药,而有的服了四分之一剂量的外酯。 |
| 34 | The researchers then took samples one, three and five hours later | 研究人员在1、3和5小时后采集了样本 |
| 35 | from the quadriceps above each participant's knee. | 从每个参与者的膝盖上方的四角形。 |
| 36 | While leucine triggered the muscle's response across the board, | 虽然Leucine引发了肌肉的全面反应, |
| 37 | those who had received a full dose of whey enjoyed the most prolonged period of muscle synthesis. | 那些接受过全剂量疗效的人 享受最长时间的肌肉合成 |
| 38 | How does whey compare to rival protein powders? | 和竞争对手的蛋白质粉相比怎么样? |
| 39 | Casein, the protein of the solid curds from which whey is separated during cheese making, | Casein 奶酪制造过程中 与奶酪分离的 固化块的蛋白质 |
| 40 | is less leucine heavy. | 莱辛的重量较低 |
| 41 | It makes up 8% of the powder's mass. | 它占粉末质量的8%. |
| 42 | That means it will not be as effective immediately after a workout, | 这意味着它不会 如此有效 之后, |
| 43 | but it does contain a good balance of other essential amino acids. | 但它确实包含 良好的平衡 其他必需的氨基酸。 |
| 44 | Pea and soya powders, in contrast, have less protein per serving overall. | 相形之下,豆粉和豆粉的蛋白质总含量较低。 |
| 45 | Whey itself comes in refined varieties. | Whey本身是精细的品种。 |
| 46 | There are isolates with less lactose for those wanting to avoid calories | 有一些隔离点 乳糖较少的人想要避免卡路里 |
| 47 | and hydrolysates pre-digested with enzymes to make the powder easier on the gut. | 并用酶水解前消化,使粉末在肠道上更容易. |
| 48 | Such concoctions are often touted as offering greater benefits owing to their more refined nature. | 此类配合物由于具有更精细的性质,往往被说成提供了更大的好处。 |
| 49 | But a study published in Nutrition and Metabolism in 2021 | 但2021年发表于"营养与代谢论"的研究 |
| 50 | found little evidence they boost muscle synthesis any more than pure whey. | 几乎没有什么证据能促进肌肉合成 |
| 51 | For gym buffs looking for a quick recovery after a workout, | 对于健身房的buffs 寻找一个快速恢复 之后的锻炼, |
| 52 | then a full dose of unadulterated whey is the best bet. | 那么,一整剂未成熟的草 是最好的赌注。 |
| 53 | A few ingredients are best avoided. | 最好避免一些成分。 |
| 54 | Some powders are leavened with glycine and taurine, | 有些粉末用甘油和薄荷 |
| 55 | amino acids that can be synthesised cheaply. | 可廉价合成的氨基酸. |
| 56 | These inflate a product's amino acid count while doing little to stimulate muscle growth. | 这些会充电一个产物的氨基酸计数,同时很少做刺激肌肉生长的工作. |
| 57 | Some makers bulk up their products with starches, gums and emulsifiers too. | 一些制造厂商也用淀粉、口香糖和乳化剂将产品大量包装。 |
| 58 | Buyers should remember not all that glitters is muscle building gold. | 买家们应该记得 光滑的不是肌肉造金 |
