哈佛大学的一项研究发现，每周进行五小时以上的高强度运动无法获得更多益处，对于避免过早死亡没有帮助。这项对10万名美国人为期30年的研究分析了运动如何影响一个人的死亡风险。研究发现，每周进行75分钟的剧烈运动（每周建议剧烈运动量）可以将死于心血管疾病的风险降低31%。然而，每周进行5小时以上剧烈运动对健康并没有任何额外益处。

There is no benefit to doing more than five hours of high intensity exercise a week, a Harvard study has found, as it does not help to stave off an untimely death.

However, pushing your body as hard as you can does not have any damaging health effects, as some previous studies have claimed.
然而，与此前的研究结果不同的是，尽可能多运动并不会对健康产生任何损害。
A 30-year Harvard study of 100,000 Americans looked at how exercise impacted a person’s risk of death.
哈佛大学对10万名美国人进行了一项为期30年的研究，分析运动如何影响一个人的死亡风险。
It found that doing 75 minutes of vigorous exercise a week, the recommended amount, slashes the risk of dying from cardiovascular disease by 31 percent.
研究发现，每周进行75分钟的剧烈运动（每周建议剧烈运动量）可以将死于心血管疾病的风险降低31%。
People who do twice this - two and a half hours of intense exercise a week - were shown to benefit slightly, further reducing the threat of death by between two and four percent.
