「每天一万步」可能是最广为流传的健康目标，但一项发表在《英国运动医学杂志》上的大型新研究发现：走多少步固然重要，走多快同样关键。研究团队分析了近6.5万名英国成年人的数据，参与者佩戴运动追踪器一周，随后被随访约8年。结果显示：每天保持较快步速（约每分钟80步）步行至少30分钟的人，早逝风险明显降低；每天走不到5000步但走得快的人，获益与走5000-7500步但速度慢的人相当。而每天走7500-10000步的人，无论快慢，风险都是最低的。有趣的是，「一万步」这个数字其实源于上世纪60年代日本的一家计步器营销活动，并非科学结论。对没时间长时间走路的人来说，加快脚步、走得更带劲，同样是对心脏好的投资。

Here's a piece of health news that might change how you take your next walk. A major new study says you don't need ten thousand steps a day to live longer. You just need to walk a little faster.
Researchers from Australia and Spain looked at data from nearly sixty-five thousand adults in the U-K. Each person wore a fitness tracker for one week. The scientists then followed them for about eight years.
The results were striking. People who walked briskly for at least thirty minutes a day had a much lower risk of dying early. In fact, those who took fewer than five thousand steps, but walked at around eighty steps per minute, showed benefits similar to people taking seven thousand steps at a slower pace.
Interestingly, the famous ten thousand step goal actually started as a marketing slogan in nineteen sixties Japan, not from science.
So here's the takeaway: every step counts, but some steps count for more. Pick up the pace until you feel warmer and breathe a little harder, and your heart will thank you.
