各位好！前两天一位好朋友在外语群里讲，他办了卡去健身，可见大家对于锻炼与健康之间的关系还是非常关注的。最近看了美国一家EHS网站上的一篇文章，就介绍了体育锻炼与女性罹患心脏疾病之间的关系，据称每周2.5小时，可以降低25%罹患冠心病的概率。

The American Heart Association recently published a study that provides further support for well-rounded employee wellness programs.
美国心脏协会最近公布了一项研究，研究为员工全面健康项目提供了进一步的支持。
Women under 50 who spend a cumulative 2.5 hours a week doing recreational physical activity are linked with a 25 percent lower risk of coronary heart disease, according to the research.
根据研究，那些每周累计花费2.5小时用来进行休闲型体育锻炼的50岁以下的女性与降低患冠心病25%的风险之间存在关联。
The benefits of physical activity for cardiovascular health in general have been shown in numerous studies, but most focused on middle-aged and older adults. Although death rates from coronary heart disease are low among women age 25-54, there has been little improvement in these rates in the past 20 years, whereas the rate among older groups has fallen during this period, according to the study.
在诸多的研究中，体育锻炼对于心血管健康的好处已被证明，但这些研究绝大多数将研究的重点放在了中老年人身上。根据研究，25至54之间的女性患上冠心病而死亡的比例低，而在过去的20年，已经有小幅改善，在这一时期，老年群体患冠心病的比例已经下降。
“Most women can improve their heart health significantly by incorporating some moderate or vigorous physical activity into their regular routine,” said Andrea Chomistek, Sc.D., lead author of the study, in a statement.
研究团队领头人Andrea Chomistek在一份声明中称：大多数女性都可以通过将一些中度及剧烈的体育锻炼加入到常规的锻炼中，通过这种方式可以极大地改善他们的心脏健康水平。
At the start of the study, they found women ages 27-44 with the highest level of leisure time physical activity were at a 25 percent lower risk incidence of coronary heart disease. In addition, the frequency of physical activity did not affect the outcome as long as the total weekly time was at least 150 minutes and , regardless of their body weight when they began, women reduced their coronary heart disease risk by engaging in physical activity.
研究初期，研究人员发现，那些参加休闲体育锻炼时间最多的27到44岁之间的女性，罹患冠心病风险降低25%。另外，体育锻炼的频次并不影响结果，只要每周锻炼时间不少于2个半小时，无论她们开始锻炼时的体重如何，她们都会在体育锻炼中降低罹患冠心病的风险。
“Physical activity appears to be beneficial across the lifespan, regardless of body weight. It’s important to remember that any amount of activity is better than none,” Chomistek said.
Chomistek称，“体育锻炼似乎对于整个生命都是有益的，这与人的体重没有关系。记住任何的体育锻炼有总比没有好，确实很重要”。
About half of U.S. employers offer some type of workplace wellness program. Roughly half of the wellness program participants showed positive changes in their walking activities and eating habits, according to a 2013 RAND Health study.
根据兰德健康2013年的一项研究，大约有一半的美国雇主提供了一些工作场所的健康计划，大约有一半的健康计划参与者在步行活动及饮食习惯上显示出了积极的变化。
