雅思课外阅读--马拉松，跑or不跑？ 3

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.

同时，平日锻炼的人也应该明白，频繁的运动训练确实会引起“心脏的生理和结构发生重大改变。”汤普森博士及其同事们在该综述中写道。

【经典句式】

work out 锻炼

frequent频繁的

exercise training运动训练

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.

他们指出，短期看来，这些改变有点像心脏损伤，也就是说，在剧烈运动之后，心脏细胞往往会“漏”，将蛋白质释放入血液——在其他情况下，这可能预示着心肌梗死。不过，这些蛋白质通常几天内就会消失，心脏也完全“康复”了，汤普森博士说。

heart damage心脏损伤

point out指出

strenuous workout剧烈运动

indicate说明

heart attack心脏病发

recover fully完全恢复

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.

但是在这个过程中，心脏出现了适应性改变：左、右心室扩大，从形态上开始与那些非运动员的心脏有了很大差异。

【经典句式】

in the process在这个过程中

adapt适应

enlarge扩大

different than跟……不同

non-athlete非运动员

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.

这些变化对于大多数人来说都是有益的，对于取得优异的运动表现也是必要的。不过，正如汤普森博士和他的同事所写的那样，他们在做完研究综述后发现，世事总有例外，有些人看似健康，但剧烈运动却可能给他们带来意想不到的危险。

【经典句式】

beneficial有益的

necessary for必要的

athletic performance优异的运动表现

colleague同事

indicate说明

outlier例外

seemingly看似

strenuous exercise剧烈运动

hold unexpected dangers带来意想不到的危险

【犀利观点】运动过度：运动有益健康

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.
