目的：高心肺适能水平可降低年龄相关的动脉壁粘度（AWV）。然而，AWV在运动训练的运动员还没有被确定。我们设计了一个横断面研究，以比较中央AWV和遵守之间的训练的年轻运动员和年龄匹配的control manifest.MethodsTwenty-one训练的男子（年龄20.7 ± 0.3岁）和20个年龄匹配的健康对照男性（年龄21.6 ± 0.4岁）进行了研究。通过眼压测量和B型图像自动跟踪无创测量颈总动脉，以获得瞬时压力和直径滞后环，并计算动态颈动脉顺应性，静态结果接受过抗压训练的男性的AWV指数大于对照组s/mm（2285 ± 181）vs.1429 ± 124 mmHg·s/mm（P< 0.001）。此外，动态和静态的依从性没有统计学差异两组之间。ConclusionThe本研究表明，中央AWV在运动训练的运动员大于年龄匹配的健康对照男性。我们认为，AWV，以及动脉顺应性，是评估血管适应耐力训练的重要因素。
PurposeThe age-associated increase in arterial wall viscosity (AWV) is attenuated by high cardiorespiratory fitness level. However, AWV in endurance-trained athletes have not been determined. We designed a cross sectional study to compare central AWV and compliance between endurance-trained young athletes and age-matched control men.MethodsTwenty-one endurance-trained men (age 20.7 ± 0.3 years) and 20 age-matched healthy control men (age 21.6 ± 0.4 years) were studied. The common carotid artery was measured noninvasively by tonometry and automatic tracking of B-mode images to obtain instantaneous pressure and diameter hysteresis loops, and we calculated the dynamic carotid arterial compliance, static (effective and isobaric) compliance, and viscosity index.ResultsThe AWV index in the endurance-trained men was larger than the control peers (2285 ± 181vs.1429 ± 124 mmHg·s/mm:P< 0.001). In addition, dynamic and static compliance were not statistically different between both groups.ConclusionThe present study indicated that the central AWV in endurance-trained athletes was greater than age-matched healthy control men. We believe that the AWV, as well as arterial compliance, is an important element for assessing vascular adaptation to endurance training.
