“运动药丸”有望取代健身房

“阻止肌肉抑制素生成的药物同时也可以用于治疗肌肉萎缩类疾病，比如癌症、肌肉萎缩病还有艾滋病。肌肉抑制素广为人知的作用就是有效抑制骨骼肌的生长。”

Studies suggest that obese people produce more of the protein, making it harder for them to exercise and build up muscle.

研究表明，肥胖的人会产生更多肌肉生长抑制素这种蛋白质，这让他们更难进行运动和增肌。

"Given that exercise is one of the most effective interventions for obesity, this creates a cycle by which a person becomes trapped in obesity," said Dr Butcher.

布彻博士说：“而运动又是防止肥胖的最有效方式之一，这就导致肥胖的人陷入恶性循环。”

The researchers bred four groups of lean and obese mice that were genetically programmed either to produce uninhibited levels of myostatin or to be completely lacking in the protein.

研究人员饲养了四组瘦弱和肥胖的小白鼠，其基因设定分别为无限制释放肌肉抑制素和完全不释放肌肉抑制素。

As expected, mice with no myostatin became markedly more muscular.

同预期一样，体内不释放肌肉抑制素的小白鼠明显肌肉更强壮。

Obese mice unable to produce myostatin remained fat, but they were also stronger and showed markers of heart and metabolic health on a par with their lean counterparts.
