Older people who regularly exercise at moderate to intense levels may have a 40% lower risk of developing brain damage linked to ischemic strokes, certain kinds of dementia and mobility problems. 有规律地锻炼且锻炼强度适中的老人可以降低脑危害的风险，这个风险可能是缺血性脑中风、某些各种各样的脑中风和流动性问题。 New research published Wednesday in the journal Neurology says the MRIs of people who exercised at higher levels were significantly less likely to show silent brain infarcts — caused by blocked arteries that interrupt blood flow and are markers for strokes — than people who exercised lightly. 发表在周三的神经病学杂志说高水平锻炼人的核磁共振的图像说明患病的情况要明显地少于那些表现的沉寂的大脑，很少锻炼的人的大脑可能引起动脉阻塞，动脉阻塞就会打乱血流，这就是脑中风的标志。 Until now, studies have shown exercise helps lower blood pressure, bad cholesterol and insulin levels, all risk factors for strokes causing brain damage. Treating those conditions is helpful, but often brain damage from multiple infarctions is not reversible. 直到现在，研究显示运动可以降低血压、降低胆固醇和胰岛素水平。脑中风的高危因素能引起大脑危害。处理这些因素是非常有用的。但是受到多重梗塞的经常性的脑危害是不可逆的。 |
