摘　　要：内皮功能异常与多种心血管疾病的发生发展密切相关,文章旨在了解运动锻炼对血管内皮功能的影响。以60名老年人为研究对象,测定心率、血压、体脂和内皮素含量,结果发现经常参加锻炼的老年男性或女性收缩压均比不锻炼的对照组低(P<0.05),锻炼组女性的心率也显著低于对照组(P<0.05),血浆内皮素水平锻炼组均低于同性别的对照组。比较不同性别内皮素含量,发现女性的内皮素水平有低于男性的趋势,但差异未达显著性。结果表明规律性有氧耐力运动改善了内皮功能,经常参加运动锻炼的人从锻炼中获得良好的生理性效果。Endothelin-1, which is produced by vascular Endothelial cells, has potent constrictor and proliferative activity in vascular smooth muscle cells and has been implicated in regulation of vascular tonus and progression of atherosclerosis. In search of signs of Endothelial function, the authors measured plasma ET-1 concentration , blood pressure , heart rate and body fat in healthy older mans and women. The results showed that the plasma level of ET-1,blood pressure and heart rate significantly lower in exercise group than in control group. This study suggests that regular aerobic-endurance exercise reduces plasma ET-1 concentration , and this reduction in plasma ET-1 concentration may have beneficial effects on the cardiovascular system.
