溫和運動如散步提高記憶力
Walking for 40 minutes a few times a week is enough to preserve memory and keep ageing brains on top form, research shows. Moderate exercise increased the size of the hippocampus, an area of the brain that makes memories, in 120 volunteers.
研究顯示，1周幾次40分鐘的散步，足以保存記憶且讓老化的大腦保持巔峰。溫和運動讓120名志願者腦中製造記憶的區塊「海馬迴」變大。
The latest work looked at healthy people in their 60s rather than people with Alzheimer’s or other forms of dementia. But the findings have important implications for ageing societies faced with a dementia time bomb.
這份最新研究觀察60多歲的健康人，而不是有阿茲海默症或其他失智症的患者，不過，其發現對於面對失智症定時炸彈的高齡化社會具有重大意義。
Professor Kirk Erickson and colleagues from the University of Pittsburgh in the US set out to investigate the impact that even moderate exercise might have on preserving memory.They split their 120 volunteers into two groups. One group was asked to begin an exercise regimen of walking around a track for 40 minutes a day, three days a week, while the others were limited to doing simple stretching and toning exercises.
美國匹茲堡大學艾利克森教授與同僚，著手調查即使是溫和運動對保存記憶產生所可能產生的影響。他們將120名志願者分成兩組，1組被要求每天繞跑道散步40分鐘、每周3天的運動治療，另1組則只做簡單的伸展及塑身運動。
Brain scans and memory tests were performed at the start of the study, halfway through the study and again at the end. Scans revealed hippocampus volume increased by around 2% in people who did regular aerobic exercise. The same region of the brain decreased in volume by 1.4% in those who did stretching exercises, consistent with the decrease seen in normal ageing.
研究開始、進行到一半以及研究結束後，都會做腦部掃描與記憶測驗。掃描顯示，規律做有氧運動的人，海馬迴容量增加約2%，做伸展運動者，同區塊容量減少了1.4%，與正常老化減少的幅度相符。
