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.
美国卫生和公共服务部建议成年人每周至少进行150分钟的中等强度到高强度的体育锻炼，并且每次运动中至少应有10分钟长的剧烈式训练，这样才能获得实质性的健康益处。
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?
这导致许多人怀疑短暂运动的无效性。如果每次运动要10分钟以上对健康才有好处，为什么我还要花两分钟去走楼梯呢?
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.
但是现在一项研究提出了其他看法：继续坚持走楼梯!计入到150分钟锻炼目标里的每一分钟都很重要，无论这一分钟是否包含在一次10分钟剧烈运动的时长里。
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.
在犹他大学进行的这项研究的目的是，观察单次不到10分钟的中度到高强度的剧烈运动与体重结果的关系
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.
这项发表在“美国健康促进杂志”上的研究发现，每次进行的某种中度到高强度的运动-无论是遛狗，用吸尘器打扫卫生还是走楼梯-都会促使体重指数降低和体重减轻。
"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.
“这里要表达的观点是，你可以每次只锻炼一分钟，这样做没有问题，”新论文的主要作者，犹他大学的家庭和消费者研究教授，在今日网(Today)上说道。
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.
对于参与该研究的女性而言，在高强度运动中进行的每分钟锻炼都使体重指数(BMI)下降了0.07。对于一个5英尺4英寸的女性来说，这意味着体重减少了将近半磅，这可能听起来也不是很多，但这只是运动了一分钟啊。他们补充道。
目前以10分钟为周期的运动指南是出于对身体健康的考虑而没有考虑体重结果
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."
作者得出结论，目前以10分钟为周期的运动指南是出于对身体健康的考虑而没有考虑体重结果。他们的研究结果表明，在预防体重增加方面，累计时间不到10分钟的高强度体育锻炼对身体来说也是非常有益的，从而为“每分钟的锻炼都很重要”这一信息提供了证据支持。
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.
当这种锻炼运用到大脑领域的时候，这一说法仍然成立。2019年4月在Jama Network Open进行的一项研究，调查了运动如何影响大脑，研究发现，即使短暂的剧烈运动也能导致脑容量增加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.
“我们的研究结果并没有证明适度或剧烈的体育活动对健康老龄化正产生重要影响。我们只是增加了科学性，揭示了轻强度的体育活动可能也很重要，特别是对于大脑而言，”博士，这位来自波士顿大学的首席研究者在接受“卫报”采访时说。
"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."
“我认为人们更容易处理和接纳这个信息，”范说。“否则，如果他们没有比较多而集中的时间，他们可能会气馁，然后就什么都不做。”
Every single minute of physical activity helps health,study shows
研究表明，每一分钟的体育锻炼都对健康有益。
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.
忘记必须进行10分钟的剧烈运动才有效的想法。新的研究发现，即使短暂的运动也可以帮助你实现目标。
