| 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。 |
| 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%。 |
| However, fitness fanatics who do more than four times the recommended amount of vigorous weekly exercise - 300 minutes, or five hours - do not get any additional benefit, data show.然而，数据显示，每周进行5小时剧烈运动（每周建议剧烈运动量四倍以上）的健身狂并没有额外获益。 |
| The same trend was seen for moderate activities, including walking. Ten hours of moderate exercise - four times the recommended weekly activity level - had no benefits, but also no harms.走路等适度运动也呈现出同样的趋势。十个小时的适度运动（每周建议运动量的4倍）既没有益处，也没有害处。 |
| Hoon Lee, study author, from the Harvard TH Chan School of Public Health, in Boston, added: “The potential impact of physical activity on health is great, yet it remains unclear whether engaging in high levels of prolonged, vigorous or moderate intensity physical activity above the recommended levels provides any additional benefits or harmful effects on cardiovascular health.”该研究论文作者、波士顿哈佛陈曾熙公共卫生学院的李勋（音译）表示：“体育运动对健康的潜在影响很大，但目前尚不清楚长时间、剧烈或中等强度的体育活动是否会对心血管健康产生额外的益处或害处。” |
| But the new study finds that to be untrue, as even people doing more than five hours a week of intense activity showed no adverse health effects.但这项新的研究发现，这种说法不成立，因为即使人们每周进行五个小时以上的剧烈活动，也不会对健康产生不利影响。 |
| "Our study provides evidence to guide individuals to choose the right amount and intensity of physical activity over their lifetime to maintain their overall health.”“我们的研究提供了依据，人们可以据此选择适当的运动量和强度，以保持健康。” |
