文章大意:本文是一篇说明文。文章主要介绍了一项研究表明,即使只进行一到两次每周锻炼,也能提高长寿的机会。即使是肥胖的人也可以通过每周锻炼几次来延长寿命。然而,为了获得最佳健康效果,建议进行更多的锻炼。世卫组织建议,成年人每周至少进行150分钟中度到高强度的活动。
Exercise is good for us. It reduces the risks of dying from all causes, including cancer and heart disease. But many people who work all week have little time for exercise. So, they might try to do something to increase their heart rates over the weekend—go for a long run, take a bike ride or hike in the mountains. But is it healthy to avoid exercise during the workweek and then try to fit it all in during the weekend?
A new study suggests that, yes, it is healthy. Australian researchers at the University of Sydney did the study. It took place over a nineyear period. During that time, the researchers looked at the selfreported exercise habits and health examinations of more than 63,000 adults in England and Scotland. Then they connected that information to death records.
The researchers found that people who exercised only one or two days a week improved their chances of living longer than people who did not exercise at all. Even those who are fat could extend their lives by exercising a couple of days per week.
Emmanuel Stamatakis is the senior author of the study. He says that he found it very encouraging that even people who exercised as little as one or two times a week appear to lower their risk of early death. In other words, their health improves even if they don’t meet the suggested weekly amount of physical activity. However, to be in the best health, Stamatakis says more exercise is better.
The WHO suggests that adults should get at least 150 minutes of moderate to intense activity per week. For the best results, the organisation suggests 75 minutes per week of intense physical activity. However, if you are busy with work and family duties, exercise as much as you can.
