At the same time, those of us who work out should understand that frequent exercise training causes“profound changes in cardiac physiology and structure,” as Dr. Thompson and his colleagues write in their review.

同時，平日鍛煉的人也應該明白，頻繁的運動訓練確實會引起“心臟的生理和結構發生重大改變。”湯普森博士及其同事們在該綜述中寫道。

【經典句式】

work out 鍛煉

frequent頻繁的

exercise training運動訓練

colleague同事

In the short term, these changes can mimic heart damage, they point out, with cardiac cells often becoming “leaky”after strenuous workouts or events, releasing proteins into the bloodstream that, in other circumstances,could indicate a heart attack. These proteins usually disappear within a few days, and theheart seems to recover fully,Dr. Thompson said.

他們指出，短期看來，這些改變有點像心臟損傷，也就是說，在劇烈運動之后，心臟細胞往往會“漏”，將蛋白質釋放入血液——在其他情況下，這可能預示著心肌梗死。不過，這些蛋白質通常幾天內就會消失，心臟也完全“康復”了，湯普森博士說。

But in the process, the heart adapts and changes. Its left and right ventricles enlarge.It begins to look quite differentthan a non-athlete’s heart.

但是在這個過程中，心臟出現了適應性改變：左、右心室擴大，從形態上開始與那些非運動員的心臟有了很大差異。

in the process在這個過程中

adapt適應

enlarge擴大

different than跟……不同

non-athlete非運動員

For most people, these changes are beneficial and also necessary for successful athletic performance. But, as Dr.Thompson and his colleagues write, their review of the studies indicates that there are outliers,seemingly healthy people for whom strenuous exercise holds unexpected dangers.

這些變化對于大多數人來說都是有益的，對于取得優異的運動表現也是必要的。不過，正如湯普森博士和他的同事所寫的那樣，他們在做完研究綜述后發現，世事總有例外，有些人看似健康，但劇烈運動卻可能給他們帶來意想不到的危險。

【經典句式】

beneficial有益的

necessary for必要的

【犀利觀點】運動過度：運動有益健康

Working out is beneficial and also necessary for successful athletic performance. But there are outliers, seemingly healthy people for whom strenuous exercise holds unexpected dangers.
