跑步6個月，壽命多3年

If you think running is a waste of time, you might want to reconsider. A new study suggests that one hour of running could elongate your life by nearly seven hours, earning you more time than you spend on the activity.

如果你認為跑步是一件浪費生命的事情，看完這篇文章后你該重新考慮一下了。有研究表明，一小時的跑步可以延長七個小時的生命，也就意味著，你在運動上賺的時間比你消耗的更多。

The review, recently published in Progress in Cardiovascular Disease, is a followup to a different study from the Cooper Institute a few years back. The previous research suggested that even small amounts of running each day could increase life span, but the data left a lot of questions unanswered, which this followup review sought to answer. Most notably, researchers wanted to know how much time you had to put into cardio-heavy activity to get time out of it. For example, to extend your life by an hour, would you have to run for an hour? If so, that would hardly seem worth it to most people.

幾年前，由庫伯實驗室(Cooper Institute)做出的研究表明，每天進行少量的運動就可以延長生命，但實驗的數(shù)據(jù)存在著很多問題沒有被回答。研究人員想知道你必須花多少時間進行有氧運動才能獲得延長的生命。比如，為了延長一小時生命，你需要運動超過一小時么?如果答案是正確的，那對于大多數(shù)人來說這是得不償失的。一篇最近發(fā)表在心血管疾病進展期刊上的報告對這些問題進行了解答。

Not only did consistent running seem to drop the risk of premature death by almost 40%, the activity seemed to statistically return more time to runner’s lives than it consumed. Say you ran for about two hours every week (which is less than 20 minutes every day). Over the next 40 years you’d spend less than six months of that time doing the activity, but, according to the review, you’d possibly increase your life expectancy by another 3.2 years. That’s a net gain of around 2.7 years, or in simpler terms, for every hour you run you lengthen your life by another seven hours (six net).

在對數(shù)據(jù)進行分析后，研究人員得出了一個令人鼓舞的結(jié)果。不僅堅持跑步的人過早死亡的幾率下降了約40%，而且跑步給這些人帶來了比所消耗的還多的生命。比如說，你每周跑步兩小時(大約每天不到20分鐘)。接下來的40年，你可能因為跑步損失了不到6個月的生命，但是，從研究結(jié)果來看，你的壽命能平均延長3.2年。所以你相當于凈賺差不多2.7年的時間?；蛘?，我們簡單來說，你每跑一小時，就能凈賺6個小時的生命。

The longevity benefits aren’t without limits, however. As co-author Dr. Duck-chul Lee, professor of kinesiology at Iowa State University, explains, running won’t let you live forever. Lee says you cap out at around three extra years, regardless of how much extra running you do over your lifetime, which isn’t the best news for long-distance runners who really crank out the miles. The data showed that improvements to life expectancy plateaued somewhere around four hours of running per week. But the good news is prolonged running doesn’t seem to be counterproductive either. Runners who went well beyond the average running time each week didn’t see any declines in health or life expectancy.

然而，這種延長生命的手法有著一定的限制。論文合著者愛荷華州立大學的運動學教授李達哲音譯: Duck Chul Lee博士說到：跑步不會讓你長生不死。李博士說，無論你跑了多久，你最多只能延長3年多壽命。這可能對于長跑運動者不是什么好消息。數(shù)據(jù)顯示，預期壽命的增長在每周跑步四小時后趨于穩(wěn)定。但好消息是，長期跑步似乎也不會導致預期壽命下降。在每周跑步時間遠遠超過平均跑步時間的跑步者身上上，研究人員沒有看到任何健康水平或預期壽命值的下降。

Walking, cycling, and other cardio activity had life prolonging benefits as well, but running seemed to provide the best return of time investment. Lee and his fellow researchers aren’t sure why that is, but it may have something to do with how it raises your overall aerobic fitness, and that is one of the best-known indicators for your long-term health.

步行，騎自行車等其他有氧活動也可以延長生命，但是跑步似乎是投資回報率最高的一種運動方式。李博士和其他研究人員不清楚為什么是這樣，但跑步似乎與提高身體的整體有氧運動水平這一指標有關(guān)。

That said, as with other similar studies, it’s important to note that correlation doesn’t equal causation. What this data actually proves is that people who run tend to also live longer, but not necessarily that running is the main reason for that. Dr. Lee notes that runners also tend to lead healthier lives in general, so other lifestyle choices, like diet and sleep, likely play a major role as well. Even so, this new data sheds more light on the many perks of cardio workouts, and how you can benefit from them down the road. So lace up those shoes and run for your life.

也就是說，與其他類似研究一樣，我們需要注意相關(guān)性并不等于因果關(guān)系。也就是說，數(shù)據(jù)研究結(jié)果證明，堅持跑步的人確實能活的更長，但是跑步不一定是導致壽命增長的主要原因。李博士指出，跑步者也通常會選擇健康的生活方式、過著更健康的生活。這些健康的生活方式，比如飲食和睡眠，也可能在延長生命中發(fā)揮了重要的作用。但即使如此，數(shù)據(jù)也顯示了有氧運動具有許多優(yōu)點，人們也可以從中受益。所以，換上運動鞋，我們一起去跑步吧。
