It's time to add to your list of reasons to work out: Getting active could help prevent risk of death from the flu and pneumonia, according to new research.
是时候给你去健身的理由上增加一条了：一项新的研究发现，积极锻炼有助于降低死于流感和肺炎的风险。
Aerobic and muscle-strengthening activities reduce the risk of dying from influenza and pneumonia by 48%, according to a study published Tuesday in the British Journal of Sports Medicine.
周二发表在《英国运动医学杂志》上的一项研究发现，有氧运动和肌肉强化训练可将死于流感和肺炎的风险降低48%。
Adults should get at least 150 minutes of moderate aerobic physical activity and two or more days of moderate muscle strengthening activities a week,
成年人每周应该至少进行150分钟的适度有氧运动，以及两天或两天以上的适度肌肉强化训练，
according to the Physical Activity Guidelines for Americans issued by the US Department of Health and Human Services.
这是美国卫生与公众服务部发布的《美国人体育活动指南》中写到的。
The study relied on the survey data of more than 570,000 people from the US National Health Interview Survey between 1998 and 2018.
该研究是基于1998年至2018年间涵盖了逾57万人的美国国民健康调查数据。
People were asked about their physical activity habits, and they were categorized into groups based on how well they met the recommended amount of exercise, according to the study.
研究称，调查询问了人们的运动习惯，并依据他们达到建议运动量的程度，将他们划分为不同组别。
On average, the respondents were monitored for nine years after the initial survey.
在最初调查结束后，研究人员对受访者进行了平均长达9年的监测。
There were 1,516 deaths from the flu or pneumonia in that time.
在此期间，有1516人死于流感或肺炎。
Meeting both recommendations for aerobic and muscle-strengthening activity cut the risk associated with flu or pneumonia death nearly in half,
有氧运动和肌肉强化训练均达标的人，死于流感或肺炎的风险几乎减半，
but meeting just the aerobic activity target was associated with a 36% lower risk.
而仅是有氧运动达标的人，这一风险降低了36%。
But even if you can't reach the recommended amount, some activity can still provide more protection than none, according to the study.
但研究指出，即使你达不到建议的运动量，运动还是会比不运动提供更多的保护。
Getting 10 to 149 minutes a week of aerobic physical activity was associated with a 21% decreased risk of flu and pneumonia death, the study showed.
研究显示，每周进行10到149分钟的有氧运动，可以将死于流感和肺炎的风险降低21%。
That being said, no additional benefit was seen for people who got more than 600 minutes a week of aerobic activity, the study showed.
不过尽管如此，研究也发现，每周进行600分钟以上有氧运动的人并不会额外受益。
