Exercise, of course, is in general extremely beneficial for heart health. Dozens of large-scale epidemiological studies have found that people who exercise in any amount, whether five minutes a day or two hours a day or more, are much less likely to develop or diefrom heart disease than people who are sedentary.

當然，一般而言，鍛煉對心臟健康大有益處。數十項大型流行病學研究都發現，無論是每天鍛煉5分鐘還是2個小時，鍛煉身體的人患心臟病或因心臟病死亡的風險要比久坐不動的人要低得多。

【經典句式】

large-scale大型的

heart disease心臟病

sedentary久坐不動的;定居的

【犀利觀點】運動過度：運動有益健康

But these studies, while encouraging, contain a disquieting subtext. Their plotted data typically shows some type of bell curve to the heart benefits from exercise, meaning that the morepeople work out, the less they are at risk of cardiac problems — up to a point, and then the benefits plateau or decline.

但這些研究在給予我們鼓勵的同時，也包含著令人不安的潛臺詞。根據數據繪制出的鍛煉的心臟效益曲線往往呈鐘形，這意味著，在某個點之前，鍛煉得越多，人出現心臟問題的風險就越低，但越過這個點之后，鍛煉的效益就會出現平臺期或者有所下降。

To some scientists, that finding made little intuitive sense.If a little exercise is good for the heart, why shouldn’t more be continually better?

有些科學家直覺地認為這一發現說不通。既然少量鍛煉有益于心臟，那為什么加大鍛煉量卻不會帶來更大的好處呢?

【經典句式】

make little sense說不通

intuitive直覺的

exercise運動

continually繼續地

Dr. Paul Thompson, the chief of cardiology at Hartford Hospital in Connecticut and for years a dedicated marathon runner, was particularly drawn to that issue. He and his colleagues at Hartford Hospital, along with scientists at the Radboud University Medical Center in Nijmegen, the Netherlands,recently decided to delve more comprehensively than had yet been done into the available data on the topic.

作為一名有多年經驗的馬拉松跑者，哈特福德醫院(Hartford Hospital，位于康涅狄格州)的心臟科主任保羅·湯普森(Paul Thompson)博士對這一問題特別感興趣。最近，他和他在哈特福德醫院的同事們以及荷蘭內梅亨大學醫學中心(Radboud University Medical Center in Nijmegen)的科學家們決定一同對這一課題的現有數據進行更深入全面地研究。
