健康专家称，每天快步走25分钟，可以延长七年寿命。

　　Researchers have found that moderate exercise could halve the risk of dying from a heart attack for someone in their fifties or sixties.

　　研究人员发现适度的锻炼可以使那些50或60多岁的人因突发心脏病而死亡的风险减少一半。

　　Coronary heart disease is the UK’s single biggest killer, causing one death every seven seconds, and exercise has long been seen as a way to reduce the risks by cutting obesity and diabetes.

　　冠心病是英国人健康的最大杀手，每七秒就有一人死于冠心病。一直以来，体育锻炼因可以减少肥胖症和糖尿病发生率，而被视为降低患冠心病几率的一种方法。

　　A new study presented at the European Society of Cardiology (ESC) Congress suggested that regular exercise can increase life span.

　　在欧洲心脏病学会（European Society of Cardiology，ESC）大会上发表的一项新研究表明，规律的体育锻炼可以延长寿命。

　　每天快走25分可延长七年寿命

　　A group of 69 healthy non-smokers, aged between 30 and 60, who did not take regular exercise were tested as part of the study at Saarland University in Germany.

　　作为德国萨尔兰大学（Saarland University）研究的一部分，一组69名30至60岁健康的、没有进行规律体育锻炼的非吸烟者组成的小组接受了测试。

　　Blood tests taken during six months of regular aerobic exercise, high-intensity interval training and strength training showed that an anti-ageing process had been triggered and helped repair old DNA.

　　在长达六个月有规律的有氧运动、高强度间歇运动和肌肉力量练习中，研究对象的血液检测显示，一种抗衰老过程被触发，并帮助修复衰老的DNA。

　　"This suggests that when people exercise regularly, they may be able to retard the process of ageing,” said Sanjay Sharma, professor of inherited cardiac diseases in sports cardiology at St George’s University Hospitals NHS Foundation Trust in London.

　　伦敦圣乔治大学医院英国国家医疗服务系统基金会（St George's University Hospitals NHS Foundation Trust）的运动心脏病学遗传心脏病学教授桑杰·夏尔马（Sanjay Sharma）表示：“这表明，人们可以通过有规律地锻炼延缓衰老过程。”

　　"We may never avoid be-coming completely old, but we may delay the time we become old. We may look younger when we’re 70 and may live into our nineties.

　　“我们也许无法避免最终老去，但我们可以延缓衰老到来的时间。当我们70岁时，看起来可能会更年轻，并有可能活到90岁。”

　　"Exercise buys you three to seven additional years of life. It is an antidepressant, it improves cognitive function and there is now evidence that it may retard the onset of dementia."

　　“锻炼能给你多带来三到七年的生命。锻炼是种抗抑郁剂，它能改善认知能力，现在有证据表明，它也许能延缓痴呆症的发病时间。”

　　The advice from experts is that everyone should do at least 20 minutes of walking or jogging a day, given the sedentary lifestyles and changes in diet that have contributed to high death rates from heart disease. Exercise can also improve brain functioning.

　　鉴于久坐不动的生活习惯和饮食结构的改变是心脏病高死亡率的部分原因，专家的建议是，每个人每天都应该进行至少20分钟的步行或慢跑。锻炼也可以改善大脑功能。

　　Exercise brings benefits at whatever age the person starts. People who start exercising at the age of 70 are less likely to go on to develop a condition that leads to irregular or racing heart rates in 10 per cent of people aged over 80.

　　无论什么时候开始，锻炼都能带来益处。80岁以上的人有10%会患上导致心率不齐或心跳过速的疾病，从70岁开始锻炼的人患上这种病的几率更低。

　　"The study brings a bit more understanding of why physical activity has that effect," said Christi Deaton, Florence Nightingale Foundation Professor of Clinical Nursing Research at Cambridge Institute of Public Health.

　　剑桥大学公共卫生学院临床护理研究部（Clinical Nursing Research at Cambridge Institute of Public Health）国际护士理事会教授（Florence Nightingale Foundation Professor）克里斯蒂·迪顿（Christi Deaton）表示： “研究让我们更加了解为何锻炼会有这样的作用。”

　　"It helps us understand the process of cellular ageing, as that's what drives our organ system and body ageing, and the effects physical activity can have on the cellular level.

　　“这帮助我们理解细胞老化的过程——细胞老化正是导致我们器官和身体老化的原因——以及体育锻炼能在细胞层面产生的作用。”

　　"The more active you are, and it doesn’t matter when you start, the more benefit you are going to have."

　　“你运动得越多，就能获得更多益处，这无关你什么时候开始运动。”
