男人不敌女人长寿 心血管疾病横行

  The dramatic difference between the sexes might explain why women live longer. The good news is that men of any age can improve the health of their heart simply by taking more regular exercise.

  这一巨大的性别差异可能就是女性为何更长寿的答案。所幸的是,任何年龄段的男性都可以改善自己的心脏健康状况,只要他们能更经常地锻炼。

  The results are based on the findings of a two-year study of a cross-section of the British population, which examined the effects of ageing on the cardiovascular system.

  这些结果来源于一项为期两年的研究。该研究对英国人口进行横断面分析,旨在调查年龄增长对心血管系统产生的影响。

  Professor Goldspink and a team of scientists at the university's Research Unit for Human Development and Ageing examined more than 250 men and women between 18 and 80.

  葛兹平克教授和一队科学家在(约翰摩尔)大学的人类发展及老龄化研究中心调查了250多名18到80岁的男性和女性。

  None of the volunteers had a weekly exercise routine and all were considered to have low fitness levels, but were otherwise healthy. Each volunteer underwent five hours of tests to measure their blood pressure and the performance of their heart while at rest and while they exercised on a treadmill.

  这些志愿者中无人进行每周固定的体育锻炼,健康状况一般。每位志愿者都进行了5小时的测试,期间检查他们在休息或在跑步机上时的血压和心脏状况。

  The researchers found that the large arteries in the body became stiffer and less elastic with age, causing increased blood pressure. Blood flow to the muscles and skin of the limbs was also found progressively to decrease. These changes were found to occur earlier in men, but women caught up soon after the menopause.

  研究者们发现人体内的大动脉血管随着年龄增长而逐渐僵硬缺少弹性,从而导致血压上升。人体肌肉和四肢皮肤的血液循环也日益减少。这些情况首先出现在男性身上,但女性在绝经后不久也会发生。
