英文原文
New research suggests that, even a simple exercise program might help older people with light or mild memory problems. Doctors have long advised patients to do physical activity to help keep their brains healthy, but the US government supported research marks the longest study of whether exercise makes any difference once memory starts to decline.
新研究表明，即使是简单的运动计划也可能有助于有轻度或轻度记忆问题的老年人。医生长期以来一直建议患者进行体育活动以保持大脑健康，但美国政府支持的研究是迄今为止关于记忆力开始下降后运动是否会产生影响的最长期研究。
Researchers found around 300 inactive older adults with memory changes called mild cognitive impairment (MCI). MCI is a condition that sometimes comes before Alzheimer's disease. Half of the older adults did aerobic exercises, and the rest did stretching and balance movements that raised their heart rate so little. People in both groups got attention from trainers who worked with them at youth organization centers called YMCAs around the United States.
研究人员发现了约300名记忆力发生变化的老年不活跃者，这种情况被称为轻度认知障碍（MCI）。MCI是一种有时在阿尔茨海默病之前出现的状况。其中一半老年人进行有氧运动，另一半则进行伸展和平衡运动，这些运动几乎不会提高心率。两组人员都得到了在美国各地青年基督教会协会（YMCA）工作的教练的关注。
When Covid-19 shut down gyms, the trainers helped the study participants keep moving at home by video calls. After a year of testing mental activity, showed neither group had worsened. Said lead researcher Laura Baker of Wake Forest School of Medicine in the state of North Carolina.
当新冠肺炎疫情导致健身房关闭时，教练们通过视频通话帮助研究参与者在家中进行锻炼。经过一年的精神活动测试，两组人员都没有恶化。北卡罗来纳州维克森林医学院的首席研究员劳拉·贝克表示。
Brain scans did not show the shrinkage that often goes with worsening memory problems, she said. By comparison, similar MCI patients in another long-term study of brain health, but without exercise experience.
她说，大脑扫描并没有显示记忆问题恶化时经常出现的萎缩现象。相比之下，在另一项关于大脑健康的长期研究中，类似的 MCI 患者没有运动经历。
