华尔街日报：游泳有益老年人健康

游泳有益老年人健康

      Swimming reduces blood pressure and improves artery health in elderly adults, according to a study in the American Journal of Cardiology.                游泳有益老年人健康：《美国心脏病学期刊》（American Journal of Cardiology）发表的一项研究结果表明，游泳可以降低老年人的血压并改善动脉健康状况。
      Previous studies have found similar advantages from walking exercises, but this was the first to demonstrate swimming's vascular health benefits for older, sedentary adults. Because swimming puts less stress on joints and the body's cooling mechanisms than many other exercises, it 'is an ideal form of activity for older adults,' the study's authors noted.         　　 以往的研究已经发现步行锻炼有类似效果，但这是有研究首次表明游泳对久坐的老年人血管健康有益处。这项研究的作者指出，由于游泳对关节和身体冷却机制造成的压力比其他很多运动少，因此它是老年人理想的一种活动方式。
      The researchers recruited 43 adults ages 50 to 80 years from the Austin, Texas, area. All had pre-hypertension or low-grade hypertension, but were otherwise healthy despite not having exercised regularly in the previous two years.          Gwenda Kaczor　　研究人员在德州奥斯汀地区找了43名年龄在50岁到80岁之间的成年人。所有人都有前期高血压或轻微高血压，但除此之外都很健康，尽管此前两年他们并未进行定期锻炼。
      They were assigned at random to one of two groups. The first group received 12 weeks of swimming instruction and swam 15 to 45 minutes a day, three to four days a week. The second, or control, group spent that time stretching and learning relaxation exercises.         　　 他们被随机分成两组。第一组接受12周的游泳指导，每天游15至45分钟，每周三至四天。第二组，也就是对照组，用这些时间来做伸展和学习放松练习。
      Despite losing no weight or fat, the swimmers' systolic blood pressure─measured when the heart contracts─fell 7% to 122 mmHg (millimeters of mercury) from 131 mmHg. Their arteries also showed signs of becoming more elastic and responsive to changes in blood flow.         　　 尽管体重或脂肪并未减少，但游泳组成员的收缩压（心脏收缩时测得）从131毫米汞柱降至122毫米汞柱，降低了7%。他们的动脉也显示出对血流变化的反应越来越灵活和迅速的迹象。
      The control group showed no statistically significant improvements. If these improvements could be sustained longer than the 12-week trial, they should decrease the swimmers' risk of heart disease, the researchers said.          　　对照组未显示出有统计意义的明显改善。研究人员说，如果这些改善状况可以维持超过12周试验的时间，那么就应该会减少游泳组成员患心脏病的风险。
      Caveat: The study's small size and selection of generally healthy subjects may limit its relevance to other elderly adults.          　　注意：该项研究规模较小，选择的研究对象普遍身体健康，这可能会限制该研究与其他老年人的相关性。

游泳（尤其是冬泳）对身体有各种好处，我们冬泳人最有感受······
