研究显示有氧运动可保持大脑健康





根据加拿大国际广播的报道,跑步、骑车或游泳等运动对心脏的好处是人所共知的。但是一项发表在《梅奥诊所学报》上的研究显示,有氧运动对保持大脑健康也有不少好处。

这份报告的撰写者是一群研究神经组织退行性疾病的德国专家。他们发现,人在运动时摄入高含量氧气有助于脑灰质的增加。最意想不到的是,受有氧运动影响最明显的大脑区域不是负责肢体动作的部分,而是负责认知和思考的部分。而且这种影响针对所有年龄段的人。

过去已经有研究显示,有氧运动可以促进身体产生脑源性神经营养因子。这是一种具有神经营养作用的蛋白质,有助于新的脑细胞的生长,延缓年龄造成的认知能力退化。

在CBC网站上介绍这项研究的戈德曼医生(Dr. Brian Goldman)说,如果你做不到像他那样每星期跑三次十公里长跑的话,至少也要每天锻炼几分钟,逐渐增加到30分钟。加拿大卫生部对成年人设立的锻炼标准是每个星期150分钟。
