西班牙学者进行的一项新研究表明,每天至少散步2英里(约合3.2公里)能降低人们因为呼吸疾病严重发作而住院治疗的风险,同时也能降低罹患这种疾病的风险。科学家发现,不经常锻炼的肺病患者,因肺病发作而住院治疗的比例是热爱运动患者的两倍。对于这些患者来说,每天步行2~4英里(约合3.2~6.4公里)是最适宜的运动。研究团队从西班牙的5所呼吸病诊所召集了约550名慢性阻塞性肺病患者,根据患者自我报告在一周内的行走距离,研究者计算出了他们的运动 A new study by Spanish scholars shows that walking for at least two miles a day can reduce the risk of hospitalization for a serious respiratory illness and reduce the risk of the disease. Scientists found that patients with lung disease who do not exercise often have twice as many hospitalizations for people who love exercise as a result of their lung disease. For these patients, walking 2 to 4 miles per day (about 3.2 ~ 6.4 km) is the most appropriate exercise. The team recruited about 550 COPD patients from five respiratory clinics in Spain. Based on self-reported patient walking distances over the week, the researchers calculated their movements
