The U.S.Department of Health and Human Services recommends that adults do at least 150 minutes of moderate to higher-intensity physical activity each week,and it should be in bursts of at least 10 minutes each for substantial health benefits.

　　美國衛(wèi)生和公共服務(wù)部建議成年人每周至少進(jìn)行150分鐘的中等強(qiáng)度到高強(qiáng)度的體育鍛煉，并且每次運(yùn)動(dòng)中至少應(yīng)有10分鐘長的劇烈式訓(xùn)練，這樣才能獲得實(shí)質(zhì)性的健康益處。

　　Which has led many to wonder about the inefficacy of brief activities.Why take two minutes going up the stairs if more than 10 minutes is required to make it worthwhile for health?

　　這導(dǎo)致許多人懷疑短暫運(yùn)動(dòng)的無效性。如果每次運(yùn)動(dòng)要10分鐘以上對(duì)健康才有好處，為什么我還要花兩分鐘去走樓梯呢?

　　But now a study suggests something else:go ahead,take the stairs!Every minute counts toward reaching the 150-minute goal,whether it's part of a 10-minute bout or not.

　　但是現(xiàn)在一項(xiàng)研究提出了其他看法：繼續(xù)堅(jiān)持走樓梯!計(jì)入到150分鐘鍛煉目標(biāo)里的每一分鐘都很重要，無論這一分鐘是否包含在一次10分鐘劇烈運(yùn)動(dòng)的時(shí)長里。

　　The purpose of the study conducted at the University of Utah was to see if moderate to vigorous physical activity in less than 10-minute episodes related to weight outcomes.

　　在猶他大學(xué)進(jìn)行的這項(xiàng)研究的目的是，觀察單次不到10分鐘的中度到高強(qiáng)度的劇烈運(yùn)動(dòng)與體重結(jié)果的關(guān)系

　　The study,published in the American Journal of Health Promotion,found that each minute spent engaging in some kind of moderate to vigorous physical activity—be it walking the dog,vacuuming,or taking the stairs—was associated with lower BMI and lower weight.

　　這項(xiàng)發(fā)表在“美國健康促進(jìn)雜志”上的研究發(fā)現(xiàn)，每次進(jìn)行的某種中度到高強(qiáng)度的運(yùn)動(dòng)-無論是遛狗，用吸塵器打掃衛(wèi)生還是走樓梯-都會(huì)促使體重指數(shù)降低和體重減輕。

　　"The idea here is,you can do a minute at a time and that's not a problem,"Jessie Fan,lead author of the new paper and a family and consumer studies professor at the University of Utah,told Today.

　　“這里要表達(dá)的觀點(diǎn)是，你可以每次只鍛煉一分鐘，這樣做沒有問題，”新論文的主要作者，猶他大學(xué)的家庭和消費(fèi)者研究教授，在今日網(wǎng)(Today)上說道。

　　For the women who participated in the study,each minute spent in higher-intensity activity was associated with a.07 drop in body mass index(BMI).For a 5'4"woman,that means a loss of nearly half a pound,which may not sound like much,but that's just for one minute.They add up.

　　對(duì)于參與該研究的女性而言，在高強(qiáng)度運(yùn)動(dòng)中進(jìn)行的每分鐘鍛煉都使體重指數(shù)(BMI)下降了0.07。對(duì)于一個(gè)5英尺4英寸的女性來說，這意味著體重減少了將近半磅，這可能聽起來也不是很多，但這只是運(yùn)動(dòng)了一分鐘啊。他們補(bǔ)充道。

　　目前以10分鐘為周期的運(yùn)動(dòng)指南是出于對(duì)身體健康的考慮而沒有考慮體重結(jié)果

　　The authors concluded that the current 10-minute activity bouts guideline was based on health benefits other than weight outcomes and that their findings showed that for weight gain prevention,accumulated higher-intensity physical activity bouts of less than 10 minutes are quite beneficial,supporting the message that"every minute counts."

　　作者得出結(jié)論，目前以10分鐘為周期的運(yùn)動(dòng)指南是出于對(duì)身體健康的考慮而沒有考慮體重結(jié)果。他們的研究結(jié)果表明，在預(yù)防體重增加方面，累計(jì)時(shí)間不到10分鐘的高強(qiáng)度體育鍛煉對(duì)身體來說也是非常有益的，從而為“每分鐘的鍛煉都很重要”這一信息提供了證據(jù)支持。

　　When it comes to your brain,that mantra also rings true.An April 2019 study in Jama Network Open looked at how exercise affected the brain,and even short bursts resulted in.22%greater brain volume.

　　當(dāng)這種鍛煉運(yùn)用到大腦領(lǐng)域的時(shí)候，這一說法仍然成立。2019年4月在Jama Network Open進(jìn)行的一項(xiàng)研究，調(diào)查了運(yùn)動(dòng)如何影響大腦，研究發(fā)現(xiàn)，即使短暫的劇烈運(yùn)動(dòng)也能導(dǎo)致腦容量增加0.22%。

　　"Our study results don’t discount moderate or vigorous physical activity as being important for healthy ageing.We are just adding to the science,suggesting that light-intensity physical activity might be important too,especially for the brain,"Dr.Nicole Spartarno,first author of the study from Boston University,told The Guardian.

　　“我們的研究結(jié)果并沒有證明適度或劇烈的體育活動(dòng)對(duì)健康老齡化正產(chǎn)生重要影響。我們只是增加了科學(xué)性，揭示了輕強(qiáng)度的體育活動(dòng)可能也很重要，特別是對(duì)于大腦而言，”博士，這位來自波士頓大學(xué)的首席研究者在接受“衛(wèi)報(bào)”采訪時(shí)說。

　　"I think it's easier for people to process that message,"Fan says."Otherwise,if they don't have a block of time they might be discouraged,and they don't do anything."

　　“我認(rèn)為人們更容易處理和接納這個(gè)信息，”范說�！胺駝t，如果他們沒有比較多而集中的時(shí)間，他們可能會(huì)氣餒，然后就什么都不做。”

　　Every single minute of physical activity helps health,study shows

　　研究表明，每一分鐘的體育鍛煉都對(duì)健康有益。

　　Forget the idea that only 10-minute bursts of activity are important.New research finds that even small moments of activity can help you meet your goal.

　　忘記必須進(jìn)行10分鐘的劇烈運(yùn)動(dòng)才有效的想法。新的研究發(fā)現(xiàn)，即使短暫的運(yùn)動(dòng)也可以幫助你實(shí)現(xiàn)目標(biāo)。
