有规律的耐力训练增加了中央动脉顺应性，而阻力训练则降低了中央动脉顺应性。目前尚不清楚血管系统如何适应耐力和阻力训练的组合。划船是独一无二的，因为它的训练包括耐力和力量训练。我们采用横断面研究设计，以确定动脉顺应性的15名健康，习惯划船[50 +/- 9（SD）年，11名男性和4名女性]和15名久坐不动的控制（52 +/- 8年，10名男性和5名女性）。赛艇运动员每周训练5.4 +/- 1.2天，持续5.7 +/- 4.0年。两组在年龄、身体成分、血压和代谢危险因素方面相匹配。赛艇运动员的中央动脉顺应性（同时进行颈总动脉超声和压平眼压测量）高于久坐对照组（P < 0.001），颈动脉β硬度指数低于久坐对照组（P < 0.001）。外周（股）动脉僵硬度的测量值无组间差异。划船运动员中心动脉顺应性越高，心迷走神经压力反射敏感性越高（r = 0.54，P < 0.005）。总之，中老年人定期划船运动与中央动脉弹性特性的有利影响有关。我们的研究结果表明，同时进行耐力训练可能会否定力量训练的僵硬效果。
Regular endurance exercise increases central arterial compliance, whereas resistance training decreases it. It is not known how the vasculature adapts to a combination of endurance and resistance training. Rowing is unique, because its training encompasses endurance- and strength-training components. We used a cross-sectional study design to determine arterial compliance of 15 healthy, habitual rowers [50 +/- 9 (SD) yr, 11 men and 4 women] and 15 sedentary controls (52 +/- 8 yr, 10 men and 5 women). Rowers had been training 5.4 +/- 1.2 days/wk for 5.7 +/- 4.0 yr. The two groups were matched for age, body composition, blood pressure, and metabolic risk factors. Central arterial compliance (simultaneous ultrasound and applanation tonometry on the common carotid artery) was higher (P < 0.001) and carotid beta-stiffness index was lower (P < 0.001) in rowers than in sedentary controls. There were no group differences for measures of peripheral (femoral) arterial stiffness. The higher central arterial compliance in rowers was associated with a greater cardiovagal baroreflex sensitivity, as estimated during a Valsalva maneuver (r = 0.54, P < 0.005). In conclusion, regular rowing exercise in middle-aged and older adults is associated with a favorable effect on the elastic properties of the central arteries. Our results suggest that simultaneously performed endurance training may negate the stiffening effects of strength training.
