1、Standing is better thai虽然这两天还是春寒料峭，但我们还是从日益无力的北风 声中、从日渐明媚的阳光里嗅到了春天的气息，春天就要 来了！与臃肿的衣服告别，与臃肿的身材告别，春天，正 是锻炼身体，重建体魄的好时节，别再窝在舒适的沙发上， 走出去，散散步，看！专家也是这样说。 Better some exercise than nothing,experts say.You may n ever win gold in the marath on but experts say you could at least walk toward better health.也许你永远

2、也无法在马拉松比赛中赢得金牌，但是专家们表示，至少你可以 利用散步来锻炼身体。* Researchers say it may take far less exercise than people had thought to lowerthe risk of heart disease especially for the highest risk group,middle-aged men.They want to encourage people to literally take the first step.研究人员表示，想要减低罹患心脏病的机率，并不像一般人所认为的要做许 多运动，

3、尤其是针对高危险群的中年男人而言。他们想要鼓励人们真正走岀运动 的第一步。* “ Doing something is better than doing nothing,”ays epidemiologist1 StevenN.Blair of the In stitute for Aerobics Research in Dallas.sitt in g,mov ing arou nd is better tha n sta nding.”达拉斯有氧研究机构的传染病学家，史蒂芬？布莱尔说道：“做点事总比什么都不做好，站着比坐着好，四处活动更胜于只站着不动。”* “ Lower intens

5、 men are those who do virtuallyno thi ng.布莱尔和哈斯卡尔都同意所谓高危险群就是那些从不运动的人。 Haskell says the men he studied changed their risk factors in key areas - lowering their body weight and blood pressure,while raisi ng their HDL (High Den sity Lipoprote in) cholesterol,the so-called goodcholesterol thats associat

6、ed with a decreased risk of heart disease.哈斯卡尔说，他所研究的男性中，已改变了几个关键性的危险因素减轻体重、血压降低，提高体内高密度脂蛋白的胆固醇，亦即有益的胆固醇。这种胆 固醇能降低患心脏病的危险。 Haskell says his subjects did it with a program of brisk walking 30 to 40 minutes at 3.5 to 4.5miles per hour (5.6 to 7.2 kilometers per hour) every other day.This much exercise

7、 should put your rate in the 110-125 beat per min ute range or 60 perce nt of capacity.哈斯卡尔说，他的这些研究对象因为参与一项快走的训练计划而降低了患 心脏病的危险，训练方法是：每隔1天花3040分钟以3.54.5英里(平均每小时57公里左右)的速度快走，这样的运动可使你的心率每分钟跳动110125下，或者，达到心跳极限的60%。* Thats significantly below what experts have consideredtheminimumthresholds3 for a traini

8、ng ben efit to kick in4 70 to 80 perce nt of capacity.Haskell says this range is based primarily on studies of comparatively more fit college stude nts by researchers who wan ted to detect improveme nt over comparatively shorter time periods.这个数字明显低于专家们所认为的能使任何一种训练有效的最低门坎标准，即心跳极限的 70%80% 。哈斯卡尔说，这个数字

9、是根据一些想要在短时间 内就能看岀运动效果的研究员，并针对比较健康的大学生所做的实验结果而定 的。* Blair and Haskell say the training threshold concept may be misleading,becausesmaller doses of exercise can produce some improveme nt.布莱尔和哈斯卡尔则说：“这种训练门坎的观念可能有错误。因为少量的运动也能增进健康。”* And,says Haskell,the prospect5 of having to gasp6 and strain their way

10、to betterhealth at a 70-80 perce nt target range has kept a lot of people from trying.哈斯卡尔说，“一想到要达到必须在 70%到80%范围之内的健康指标，就必须气喘如牛，竭尽全力地锻炼身体，许多人便望而却步。”exercise 30 to 40 minutes at 70 to 80 percent of capacity,three times a week no more tha n 20 perce nt of men and ten perce nt of wome n meet that criteria7, said.他说：“我们针对的是年龄45以上的人口，若使用目前的运动指标，即在30到40分钟内达到70%80% 的心跳率，一星期做3次。只有20%的男性和Blair10%的女性才能达到这样的标准。” The public may be thinking
