摘要：中央动脉顺应性的降低对全身心血管功能和疾病风险产生了许多不利影响。采用横断面研究设计，我们确定了慢性阻力训练和颈动脉顺应性之间的关系。共62名健康血压正常的男性，年龄20至39岁（年轻）和40至60岁（中年），他们是久坐或阻力训练，进行了研究。在两个活动组中，中年男性颈动脉顺应性（同时超声和压平张力计）低于青年男性（P <0.05）。久坐不动的年轻人和接受阻力训练的年轻人之间没有显著差异。在中年组，阻力训练组的颈动脉顺应性比久坐组低30%（P <0.01）。股动脉顺应性和手臂脉搏波速度（外周动脉僵硬度的测量）在任何组之间都没有差异。阻力训练组的左心室肥厚指数（超声心动图）高于久坐组（P <0.05），且与颈动脉顺应性相关（r =-0.35;P <0.01）。我们的结论是：（1）阻力训练与健康中年男性较小的中央动脉顺应性相关;（2）与年龄相关的动脉顺应性降低在阻力训练的男性中比在久坐的男性中更大;（3）阻力训练的男性中较低的动脉顺应性与左心室肥大相关。与常规有氧运动的有益效果形成鲜明对比的是，本研究结果与阻力训练对动脉壁缓冲功能产生有益影响的观点不一致。
Abstract—Reductions in the compliance of central arteries exert a number of adverse effects on systemic cardiovascular function and disease risk. Using the cross-sectional study design, we determined the relation between chronic resistance training and carotid arterial compliance. A total of 62 healthy normotensive men, 20 to 39 years of age (young) and 40 to 60 years of age (middle-aged), who were either sedentary or resistance-trained, were studied. In both activity groups, carotid arterial compliance (simultaneous ultrasound and applanation tonometry) was lower (P <0.05) in the middle-aged compared with the young men. There was no significant difference between young sedentary and resistance-trained men. In the middle-aged group, carotid arterial compliance in the resistance-trained men was ≈30% lower (P <0.01) than their sedentary peers. Femoral artery compliance and arm pulse wave velocity (measures of peripheral artery stiffness) were not different among any groups. Left ventricular hypertrophy index (echocardiography) was greater (P <0.05) in resistance-trained compared with sedentary men and was associated with carotid arterial compliance (r =−0.35;P <0.01). We concluded that (1) resistance training is associated with the smaller central arterial compliance in healthy middle-aged men; (2) age-related reductions in arterial compliance was greater in resistance-trained men than in sedentary men; and (3) the lower arterial compliance in the resistance-trained men is associated with left ventricular hypertrophy. In marked contrast to the beneficial effect of regular aerobic exercise, the present findings are not consistent with the idea that resistance training exerts beneficial influences on arterial wall buffering functions.
