輕度運動可以減輕中風的嚴重程度
People who regularly engage in light to moderate physical activity — like walking four hours a week or swimming two hours weekly — might have less severe strokes than individuals who aren’t as active, a Swedish study suggests.
瑞典的一項研究表明：經常進行輕微或者適度鍛鍊的人，例如：每周步行四小時或每週遊泳兩小時，可能比不經常運動的人患中風的機率要小。
Researchers examined data on 925 patients who were treated for strokes at Sahlgrenska University Hospital in Gothenburg, Sweden, between 2014 and 2016. Overall, four in five of these patients had mild strokes.
在2014年到2016年期間，研究人員調查了瑞典哥德堡的薩爾格倫斯卡大學醫院中925名患有中風的病人的數據。這些病人中，五分之四的病人是輕度中風。
Slightly more than half of the patients were inactive before their strokes. Compared with this inactive group, people who got at least some exercise before their strokes were twice as likely to have mild strokes, researchers reported in Neurology.
研究人員在《神經病學》(Neurology)雜誌上表示，有一半以上的病人在中風前是很少鍛鍊的，相比之下，在中風前至少做過一些鍛鍊的人患輕度中風的可能性是不鍛鍊的人的兩倍。
We knew from earlier research that physical activity could reduce stroke incidence, lead study author Malin Reinholdsson of the University of Gothenburg said by email. "However, whether or not pre-stroke physical activity could also influence stroke severity was not clear."
哥特堡大學的帶頭學者在郵件中說道：「我們在早期的研究中得知，鍛鍊身體可以減小患上中風的概率，但是，在中風前才鍛鍊能否也減小中風的嚴重程度還不得而知。」
Patients in the study were 73 years old on average and most of them had what’s known as an ischemic stroke, the most common kind, which occurs when a clot blocks an artery carrying blood to the brain. About 6 percent of patients had hemorrhagic strokes, a less common type that is caused by a ruptured blood vessel in the brain.
被調查的病人的平均年齡為73歲，他們大多數人都患有流行的缺血性中風，這是中風中最常見的一種，當輸送至大腦的血液在動脈發生結塊阻塞時易患上此病。大約有6%的病人患有出血性中風，這是中風中較少見的一種類型，當腦血管破裂時易患上此病。
