新冠疫情讓全世界都認識到了呼吸道傳染病的可怕，病毒面前，如何才能提高自身防護力？新研究發(fā)現，定期進行適量的有氧運動和肌肉強化訓練可以降低死于流感和肺炎的風險。

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.

去健身的理由又多了一個。新研究發(fā)現，鍛煉有助于降低死于流感和肺炎的風險。

Aerobic and muscle-strengthening activity reduce risk of dying from influenza and pneumonia by 48%, according to a study published Tuesday in the British Journal of Sports Medicine.

5月16日發(fā)表在《英國運動醫(yī)學雜志》上的一項研究發(fā)現，從事有氧運動和肌肉強化訓練可以使死于流感或肺炎的風險低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, according to the Physical Activity Guidelines for Americans issued by the US Department of Health and Human Services.

根據美國衛(wèi)生與公眾服務部發(fā)布的美國體育活動指南，成年人每周應該至少進行150分鐘中等強度的有氧運動，并保證每周至少有兩天進行中等強度的肌肉強化訓練。

The study relied on the survey data of more than 570,000 people from the US National Health Interview Survey between 1998 and 2018. 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.

研究基于1998年至2018年間涵蓋了逾57萬人的美國國民健康調查數據。研究稱，調查詢問了人們的運動習慣，并依據他們的達標程度將其劃分為不同組別。

On average, the respondents were monitored for nine years after the initial survey. There were 1,516 deaths from the flu or pneumonia in that time.

初步調查結束后，研究人員對受訪者進行了平均長達9年的監(jiān)測，在這期間有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, but meeting just the aerobic activity target was associated with a 36% lower risk, according to the study.

研究顯示，有氧運動和肌肉強化訓練均達標的人死于流感或肺炎的風險幾乎減半，而僅是有氧運動達標的人這一風險降低了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，即使你沒有達標，運動多少還是可以提供一些防護作用。

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.

研究顯示，每周進行10到149分鐘的有氧運動可以將死于流感和肺炎的風險降低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.

不過盡管如此，研究也發(fā)現，每周有氧運動超過600分鐘的人并不會額外受益。
