We all know that running a few kilometres each day is good for our health, right? Well, what we didn't know, until now, is that running too much could be bad for us. New research suggests that running long distances regularly for many years could shorten our life instead of extending it. The study is from the Minneapolis Heart Institute Foundation. Researcher Dr James O'Keefe said too much running can cause plaque to build up inside your heart. This can lead to heart disease. He wrote: "Years of extreme exercise…appears to erase some benefits you get from moderate exercise, so that your risk of heart disease, of dying of coronary disease, is the same as [an inactive] person."

眾所周知，每天跑幾公里有助健康，人們都這么認(rèn)為。但是我們現(xiàn)在才知道的是跑步過量也能夠傷害我們。新的一項研究表明跑步多年很有可能會縮短壽命，而不是延長壽命。這是來自明尼阿波利斯心臟研究基金協(xié)會的研究。研究人員詹姆斯·奧基弗說跑步過量將影響血小板對心臟的功能。這將會導(dǎo)致心臟病的發(fā)生。他還寫道：“多年的極限運動將會減少適度運動所帶來的好處，長期如此你將有患心臟病的風(fēng)險，或者是死于冠心病，這與不運動患心臟病的幾率是一樣的。

The researchers looked at the health and training of 3,300 runners over the age of 35. Seventy per cent ofthem ran more than 30 kilometres a week. The study found that men who were marathon runners for 25 years had 62 per cent more plaque in their heart than men of the same age who did little or no exercise. Another doctor and long-time runner, John Hagan, said he feels cheated. He has been running marathons and doing triathlons since 1967. He used to run up to 60 kilometres per week. He said: "As a physician and a runner, Ifelt betrayed. I thought I was out there exhausting myself, building an absolutely indestructible heart." Dr Hagan advised people to exercise regularly but not to overdo things.

研究人員調(diào)查了3300名年齡在35歲以上人士的健康和訓(xùn)練情況。這些人中有70%的人每周的跑步距離都超過了30公里。這項研究發(fā)現(xiàn)如果一名跑過25年的馬拉松運動員，他心臟中的血小板與同齡那些幾乎不運動的人多出了62%。約翰·赫根是一名醫(yī)生，同樣也是一名長期參與跑步運動的人，他說他感到被騙了。他一直參與馬拉松運動，并在1967年起參與鐵人三項運動。他曾經(jīng)每周的跑步距離是60公里。他說：“作為一名內(nèi)科醫(yī)生和一名跑步員，我感到人們背叛了我。我曾經(jīng)認(rèn)為我在那里揮汗如雨，目的就是想要一個無堅不摧的心臟。赫根醫(yī)生建議年輕人定期鍛煉，但要適度。
