Experts at the Centre for Diet and Activity Research - a collaboration between the universities of Cambridge and East Anglia - used computer simulations to compare the risks and benefits of exercising in polluted areas around the world.
饮食与锻炼研究中心的专家使用电脑仿真技术,比较了在世界各地污染地区进行体育锻炼的风险和益处。饮食与锻炼研究中心由剑桥大学和东安格利亚大学合作建立。
Only 1 per cent of cities are so polluted that the risks start to overcome the benefits of physical activity after half an hour of cycling.
只有1%的城市不符合上面的结论——这1%的城市因为污染太严重,以至于骑行半个小时后,体育锻炼的风险就开始超过健康收益了。
Study leader Dr Marko Tainio, of the University of Cambridge, said: ‘Our model indicates that in London health benefits of active travel always outweigh the risk from pollution.
领导该研究项目的剑桥大学马可·泰尼奥博士说:“我们的模型显示,在伦敦,体育活动的健康收益总是大于污染的危害。
‘Even in Delhi, one of the most polluted cities in the world – with pollution levels ten times those in London – people would need to cycle over five hours per week before the pollution risks outweigh the health benefits.
“即便在世界上污染最严重的城市之一印度德里,污染水平是伦敦的十倍,人们每周仍然可以骑行五个多小时,健康收益大于风险。继续增加锻炼则会危害健康。
