One Hour of Exercise a Day Fights Damage of Sitting
From VOA Learning English, this is the Health & Lifestyle report.
When it comes to your health, It seems that sitting too much may be as bad for you as smoking.
If you sit for many hours a day in a traditional office job, you may be interested in a new study. This study suggests that you should get an hour of "brisk exercise" every day.
Researchers say this brisk exercise can help office workers reduce their risk of an early death. Many office workers spend a large part of their time seated and physically inactive.
A lack of physical activity is linked to some 5.3 million deaths worldwide each year. The researchers say that makes a sedentary lifestyle more deadly than smoking.
The new report said that a sedentary lifestyle can cause many diseases, including heart disease, diabetes and even some cancers. These diseases cost the world economy $67.5 billion every year.
The U.S. Centers for Disease Control and Prevention suggests adults get 150 minutes of moderate aerobic exercise every week. In addition, CDC officials advise adults to get an additional two hours of muscle strengthening per week.
Ulf Ekelund is with the Norwegian School of Sports Sciences and the University of Cambridge. He was the lead writer of the report.
Ekelund says that "For many people who commute to work and have office-based jobs, there is no way to escape sitting for prolonged periods of time."
He says he and the other researchers "cannot stress enough" the importance of getting exercise. Ekelund suggests going for a run in the morning, riding a bicycle to work, or taking a walk in the middle of the work day.
An hour of physical activity is "ideal," he adds. But if this is not possible, he suggests doing at least some exercise each day to reduce the risk of disease and an early death.
For the study, researchers looked at 13 earlier studies on the effect of inactivity. Study subjects were grouped according to the amount of activity they reported. The range of activity reported varied greatly -- from less than 5 minutes a day to up to 75 minutes a day.
The study found that those who sat for eight hours a day, but got the suggested amount of exercise reduced their chances of dying at an early age. These people did better than those who sat less but were not active.
Ekelund says, "There has been a lot of concern about the health risks" linked "with today's more sedentary lifestyles." He says the message from his team is a positive one: it is possible to reduce, or even eliminate, these risks if we are active enough," even without taking up sports or going to the gym."
A report on the study appeared in the publication Lancet.

如果你在传统的办公室工作，一坐就是几个小时，你可能会对这项新研究感兴趣 。该研究建议，每天应该做一小时的“轻快运动” 。
研究人员表示，这种轻快运动有助于降低久坐族早逝的风险 。许多上班族大多时间是坐着不动的 。
每年，全球约530万死亡病例与缺乏身体锻炼有关 。研究人员称，久坐的危害比吸烟更致命 。
该项新报告指出，久坐会诱发多种疾病，包括心脏疾病、糖尿病甚至癌症 。这些疾病每年给全球经济造成675亿美元的损失 。
美国疾病控制和预防中心建议，成年人每周做150分钟的适度有氧运动 。此外，该机构人员建议成年人每周另外花一两个小时进行肌力锻炼 。
乌尔夫·埃克隆（Ulf Ekelund）在挪威体育学院以及剑桥大学任职 。他是这篇报告的首席作者 。
他说，他与其他研究人员反复强调锻炼的重要性 。埃克隆推荐早上跑步，骑自行车上班，或在午间休息时散步等锻炼方式 。
他补充说，每天一小时的身体锻炼是比较“理想”的 。如果不具备这样的条件，他建议每天至少做一些锻炼以降低患病和早逝的风险 。
为了进行研究，研究人员查看了13份早期关于不活动影响的研究 。根据研究对象的活动量将其进行分组 。研究对象的活动强度差距较大，范围为每天不到5分钟到每天长达75分钟 。
研究发现，每天久坐8个小时但遵照适度活动建议的人，其早逝的概率有所降低 。这些人比久坐时间短但不活动的人更健康 。
埃克隆表示，“与久坐的现代生活方式有关的健康风险倍受人们关注 。”他表示，他们的研究释放出一个积极的信号 。如果活动强度足够，我们就能减少甚至消除这些风险 。“哪怕从未进行过体育项目或者去过健身房 。”
