"While many people become discouraged about Alzheimer's disease because they feel there's little they can do to protect against it, these results suggest that engaging in moderate physical activity may slow down the progression of the disease."
“很多人对于阿兹海默症感到绝望,因为他们觉得自己无法避免患上这种病,但是研究结果表明,适度运动或许能减缓该疾病的发生。”
The study used accelerometers to measure a week's worth of physical activity for 93 middle-aged volunteers, all at high genetic risk of Alzheimer's but so far showing no cognitive signs of the disease.
该研究使用加速计测量93名中年志愿者一周的运动量,这些志愿者从家族遗传来看都有患上阿兹海默症的风险,不过尚未显示出患病的体征。
Physical activity was split into light (the equivalent of walking slowly), moderate (a brisk walk), and vigorous (a strenuous run). This collected data was then compared against glucose metabolism levels in the brain.
身体运动分为轻度(相当于慢慢行走)、适度(轻快步行)和剧烈(剧烈跑步)。收集到的数据跟大脑中的葡萄糖代谢水平进行比较。
Using a special imaging technique called 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) to trace glucose metabolism, the researchers found healthier patterns in moderately active patients in all areas of the brain under observation.
