At least an hour of physical activity a day may be required to offset the harmful effects of sitting at a desk for eight hours, according to the latest study to highlight the harm of a desk-bound lifestyle. The World Health Organisation (WHO) guideline, adopted by PHE (Public Health England), recommends 150 minutes of exercise a week but research, based on data from more than one million people, suggests that is insufficient for many.
A team of international experts found that the risk of dying during a follow-up period of two to 18 years was 9.9% for those who sat for eight or more hours a day and engaged in low activity, compared with 6.8% for those who sat for less than four hours a day and were active for at least one hour a day.
But they also found that the increased risk of death associated with sitting for eight hours a day was eliminated for people who did a minimum of one hour of physical activity a day. Lead author Prof Ulf Ekelund, from the Norwegian School of Sports Sciences and Cambridge University, said: "You don’t need to do sport; you don’t need to go to the gym. It’s OK doing some brisk walking, maybe in the morning, during lunchtime, after dinner in the evening. You can split it up over the day, but you need to do at least one hour."
The paper, published in the Lancet on Wednesday, analysed data from 16 previous studies, mainly involving people aged over 45 from the USA, Western Europe and Australia. The authors found that one hour of "moderate intensity" exercise, such as walking at 5.6 km/h or cycling for pleasure at 16 km/h, was enough to offset the ill effects of sitting for long periods.
Ekelund acknowledged that work pressures made taking lengthy breaks—the legal minimum in the UK is one 20-minute break—unrealistic for some. But he also said a five-minute break at work every hour, even to go to the printer, would be beneficial and said it was in employers’ interests to facilitate culture change.
Another study, published in the Lancet on Wednesday as part of the same series, estimates that physical inactivity costs the global economy $67.5bn (S51.5bn) per year—the UK equivalent is £1.7bn— comprising $58.8bn in healthcare and $13.7bn in lost productivity.
Independent experts who reviewed Ekelund and team’s research said it was encouraging that it suggested desk-bound time could be mitigated. Dr Erika Borkoles, senior lecturer in sports science at Bournemouth University, said: "People who sit for longer hours should be concerned and could take the findings of this research as an opportunity to be proactive."
A WHO spokesman said: "Recommendations related to sitting and inactivity are not available yet. However, WHO already recommends governments implement policy actions around making environments where people live and work more conducive to physical activity." PHE said even 10-minute bursts of activity could be beneficial.
Ekelund and his team found that sitting watching TV for over three hours per day was also associated with an increased risk of death during the follow-up period, except among the most active.
[A] has created conditions and environments for people to work out.
[B] suggests two-and-a-half-hour physical exercise per week.
[C] indicates that even a short time of exercise can do some good.
[D] has collected data from previous studies on middleagers’ exercise habits.
[E] admits that it’s difficult for some working people to get ample rest.
[F] has printed a research paper on the negative effects of physical inactivity.
[G] thinks desk-bound people should respond aggressively to the research finding.

选项
答案
F
解析
Lancet出现在第四段和第六段,解题关键句在第六段。文中提到的关于久坐不动与人体健康之间关系的调查研究,其研究成果就发表在《柳叶刀》(Lancet)上,该研究的主题即关于久坐的不良影响;且第六段也明确说到,该篇学术论文对人们久坐不动导致的经济损失作了估计。由此可见,F说Lancet“曾刊登过一篇关于缺乏运动的负面影响的学术论文”与文意相符,其中printed与原文的published对应,negative effects则是对原文提到的经济损失的概括。故F为正确答案。
