Resistance training reduces arterial compliance. Although cardiac pulsatile energy is distributed between arterial compliance and arterial wall viscosity, arterial wall viscosity in resistance-trained men remains unclear. Therefore, this study aimed to examine whether resistance-trained men exhibit increased arterial wall viscosity. This cross-sectional study included 28 young men (18-25 years), with 12 resistance-trained men and 16 non-trained sedentary controls. We measured arterial wall viscosity, arterial compliance, carotid and brachial blood pressures, peak oxygen uptake, and left ventricular mass and functions. Resistance-trained men had higher arterial wall viscosity (3064 ± 1208 vs. 1993 ± 831 mmHg·s/mm: p = 0.010) and lower compliance (0.093 ± 0.029 vs. 0.153 ± 0.054 mm/mmHg: p = 0.003) than controls, with an elevated beta-stiffness index (7.90 ± 2.80 vs. 5.86 ± 1.26 AU: p = 0.015). Intima-media thickness and brachial systolic and diastolic blood pressures, peak oxygen uptake, and stroke volume did not differ between groups, although there were significantly higher carotid systolic blood pressure and pulse pressure in resistance-trained men compared to controls. Resistance-trained men showed concentric left ventricular hypertrophy. The present study indicated that central arterial wall viscosity is higher and arterial compliance is lower in resistance-trained men.
抗阻训练会降低动脉顺应性。虽然心脏搏动能量分布于动脉顺应性和动脉壁黏性之间，但抗阻训练男性的动脉壁黏性仍不明确。因此，本研究旨在探讨抗阻训练男性的动脉壁黏性是否增加。这项横断面研究纳入了28名年轻男性（18 - 25岁），其中12名抗阻训练男性和16名久坐不动的非训练对照者。我们测量了动脉壁黏性、动脉顺应性、颈动脉和肱动脉血压、峰值摄氧量以及左心室质量和功能。与对照组相比，抗阻训练男性的动脉壁黏性更高（3064±1208 vs. 1993±831 mmHg·s/mm：p = 0.010），顺应性更低（0.093±0.029 vs. 0.153±0.054 mm/mmHg：p = 0.003），β硬度指数升高（7.90±2.80 vs. 5.86±1.26 AU：p = 0.015）。两组之间的内膜中层厚度、肱动脉收缩压和舒张压、峰值摄氧量及每搏输出量无差异，不过与对照组相比，抗阻训练男性的颈动脉收缩压和脉压显著更高。抗阻训练男性表现出向心性左心室肥厚。本研究表明，抗阻训练男性的中心动脉壁黏性更高，动脉顺应性更低。
