Do We Really Need to
Take 10,000 Steps
A Day for Our Health?
By Gretchen Reynolds
Jul. 6, 2021
Fitness tracking devices often recommend we take 10,000 steps a day. But the goal of taking 10,000 steps, which many of us believe is rooted in science, in fact rests on coincidence and sticky history rather than research.
健身追踪设备通常建议我们每天走1万步。我们很多人都认为走一万步的目标是有科学依据的，但实际上这一目标的设定是源于巧合和固有的历史印象，而不是科学研究。

A 2019 study by Dr. Lee and her colleagues found that women in their 70s who managed as few as 4,400 steps a day reduced their risk of prematuredeath by about 40 percent, compared to women completing 2,700 or fewer steps a day. The risks for early death continued to drop among the women walking more than 5,000 steps a day, but benefits plateauedat about 7,500 daily steps. In other words, older women who completed fewer than half of the mythic10,000 daily steps tended to live substantiallylonger than those who covered even less ground.
李博士（哈佛大学陈曾熙公共卫生学院教授）和她的同事在2019年进行的一项研究发现，与每天走2700步或更少的女性相比，每天走4400步的70多岁女性过早死亡的风险降低了约40%。每天走路超过5000步的女性过早死亡的风险甚至更低，到每天7500步水平时，步行带来的益处达到峰值。换句话说，在老年女性中，与那些走得特别少的人相比，即便只完成了传奇1万步的一半运动量，寿命总的来说还是更长。

And if we do reach the 10,000-step target, our feattends to be ephemeral. A famous study in Ghent, Belgium, provided local citizens in 2005 with pedometersand encouraged them to walk for at least 10,000 steps a day for a year. Of the 660 men and women who completed the study, about 8 percent reached the 10,000 step daily goal by the end. But in a follow-up study four years later, almost no one was still striding that much. Most had slippedback to their baseline, taking about the same number of steps now as at the study’s start.
就算我们真的达到了1万步的目标，这样的努力通常也只是昙花一现。2005年，比利时根特的一项著名研究曾给当地居民提供计步器，并鼓励他们在一年中每天至少步行1万步。在完成研究的660名男性和女性中，大约8%的人最终做到了每天走1万步。但在四年后的一项后续研究中，几乎没有人每天还走那么多步。大多数人已经回到了他们的步数基线，每天走的步数与研究开始时大致相同。

▶ stride v. 阔步走

The good news is that upping our current step counts by even a few thousand additional strides most days could be a reasonable, sufficient— and achievable— goal, Dr. Lee said. The formal physical activity guidelines issued by the United States and other governments use time, not steps, as a recommendation, and suggest we exercise for at least 150 minutes a week, or a half-hour most days, in addition to any moving around we do as part of our normal, daily lives.
李博士说，好消息是，大多数时候，将我们当前的每日步数增加几千步可能是一个合理、足够且可实现的目标。但在美国和其他国家发布的官方体育活动指南中，建议以时间而非步数，作为衡量标准，推荐我们在完成日常活动之外，每周至少锻炼150分钟，或者几乎每天半小时。
