研究：走路快的人更长命
英国莱斯特年夜学对近47.5万人的走路习惯和灭亡环境进行了监测，发现走路快的人，寿命也更长！这项研究颁发于《梅奥诊所学报》（Mayo Clinic Proceedings）。
People who have a quicker walking pace lived longer than those who walked more slowly, according to researchers who monitored the walking habits and deaths of nearly 475,000 people, most of whom were in their 50s at the start of the study.
研究职员对近47.5万人的走路习惯和灭亡环境进行了监测，此中年夜大都人在研究起头时都是50多岁。研究发现，走路速度快的人比走路速度慢的人寿命更长。
此中，走路快的女性估计均匀寿命86.7~87.8岁，走路快的男性85.2~86.8岁。
走路慢的女性估计均匀寿命72.4岁，男性则为64.8岁，由此计较出走路快的人年夜约能多活15~20年。
走多快才算快呢？
研究职员指出，心率要到达最年夜值的60%以上，或每分钟100步，才算是“走路快”。
Brisk walkers hit speeds of 3 mph—about 100 steps a minute and, in general, they will overtake most other walkers. Slow walkers trudge along at between 1 mph and 2 mph, or just 50 steps a minute.?
走路快的人速度到达每小时约3英里（4.8千米），年夜约每分钟100步，一般来讲，他们会跨越年夜大都步行者。走路慢的人以每小时1-2英里（1.6-3.2千米）的速度行进，或说是每分钟只走50步。
走路速度反应寿命是非
持久以来，BMI（身体质量指数）被视为是权衡人体胖瘦水平和是不是健康的主要尺度。
但这项研究发现，不管BMI若何，一小我的走路速度与其寿命都是较着挂钩的。
Tom Yates, the lead author from the University of Leicester in England, attested that physical fitness may be a better indicator in measuring mortality rates compared to body mass index.?
英国莱斯特年夜学的汤姆?耶茨是这项研究的第一作者，他证实，与身体质量指数比拟，体能也许是权衡灭亡率的更好指标。
Since the results pointed out that weight was not a determining factor among the walkers but their pacing, the researchers also found that those who were underweight had a slower walking pace and were at higher risk of heart-related diseases.
因为研究成果表白走路速度而不是体重是决议性身分，研究职员还发现，体重太轻的人走路速度较慢，患心脏相干疾病的风险较高。
为何走路快的人更长命？
莱斯特年夜学的研究陈述只指出了此中的联系关系性，但专家指出，这现实上是有缘由的。
研究职员称，快步走是一种低强度有氧活动（a very low-intensity form of cardio）。
这类活动的益处是，庇护行走者免受高血压、肥胖和不勾当的影响，有助于人体血汗管健康。
These findings are consistent with other studies showing that brisk walking can cut the risk of cardiovascular events, adding to evidence suggesting that cardiovascular fitness can provide some protection against the health risks posed by having excess weight or obesity.
这些发现与其他研究成果一致表白，快步走可以下降血汗管疾病风险，这进一步证实血汗管健康可以预防超重或肥胖带来的健康风险。

别的，研究表白，即便严重超重，快步走的人的预期寿命仍比走路慢的人要高。
So, whether you're overweight or in shape, fast walking does have positive physical effects on your body and life expectancy.
所以，不管你是超重仍是体形杰出，快走城市对你的身体和预期寿命发生积极的影响。
另外，专家也暗示，比拟于久坐，即便是慢走对身体也是有益的。
Those who are sedentary are better off doing any type of walking, even at a slow pace. How much time you spend walking also shouldn’t be disregarded. It’s not just the intensity but the duration that counts.
对那些久坐的人来讲，不管进行甚么速度的步行，即便走得很是慢，也利于健康。万万别轻忽你在步行上花的时候。强度当然主要，延续时候不成轻忽。
所以，想长命仍是很多动，加点速就更好了。
