【美联社波士顿1980年5月1日电】研究人员说,甚至比较轻微的锻炼,也可以明显帮助血液破坏危险的凝块,此一发现可解释为什么经常锻炼身体的人,患心脏病的较少并且少患中风的缘故。医生们最近注意到缓慢行路或锻炼身体的人比一般人群有较健康的心脏,但他们并不了解在体内发生了何种可以保护此重要器官的情况。北卡罗来纳杜克大学医学中心的最近研究发现,当人们身体情况良好时,能释放出大量攻击血形成凝块的蛋白质。领导此研究的威廉斯(R.Sanders Wil-liams)说,在他的学说说服科学家们以前还必需作更多的研究。他说,他的小组可能发现降低患心脏病的一个“重要机制”。此研究发表于今日出版的《新英格兰医学杂志》上,对69名不定期锻炼的健康成人测定其 Associated Press, Boston, May 1, 1980 Researchers say that even modest exercise can significantly help blood damage dangerous clots, a finding that explains why people who exercise regularly have heart disease Less and less suffer from stroke. Doctors have recently noticed that people who walk slower or exercise more often have a healthier heart than the general population, but they do not know what’s going on in the body to protect that vital organ. A recent study by Duke University Medical Center in North Carolina found that when people are in good health, they release large amounts of protein that attack blood to form clots. R. Sanders Wil-liams, who led the study, said more research is needed before his doctrine can convince scientists. He said his group may find an “important mechanism” for reducing heart disease. The study, published today in the New England Journal of Medicine, examined 69 healthy adults who did not exercise regularly
