高强度抗阻训练降低了中心动脉顺应性（CAC）。心肌下存活率（SEVR）是反映冠状动脉灌注和左心室后负荷平衡的有用工具。动物研究表明，CAC降低与SEVR恶化相关。因此，阻力训练引起的CAC降低可能与SEVR的变化有关。本研究的目的是使用横断面和纵向（即，阻力训练）研究设计。为了实现这一目标，我们首先进行了一项横断面研究，以调查89名年轻男性中SEVR和CAC之间的关联。此后，进行了纵向研究，以检查阻力训练对年轻男性SEVR和CAC的影响。共有28名年轻男性被分为2组：对照组（n = 13）和训练组（n = 15）。在训练组中，受试者接受为期4周的监督阻力训练（5组，10次重复，1次重复最大值的75%，每周3次）。然后测量所有受试者的CAC和SEVR。在横断面研究中，SEVR与CAC显著正相关，而阻力训练显著降低SEVR和CAC。此外，训练引起的CAC变化与SEVR变化显著相关。因此，这些结果表明，阻力训练诱导的CAC降低与年轻男性SEVR降低有关。
High-intensity resistance training decreases central arterial compliance (CAC). Subendocardial viability ratio (SEVR) is a useful tool that reflects the balance between coronary perfusion and left ventricular afterload. Animal studies have demonstrated that decreased CAC is associated with SEVR deterioration. Therefore, resistance training-induced decrease in CAC may be associated with changes in SEVR. The objective of the present study was to investigate the association between SEVR and CAC using both cross-sectional and longitudinal (i.e., resistance training) study designs. To achieve this, we first conducted a cross-sectional study to investigate the association between SEVR and CAC in 89 young men. Thereafter, a longitudinal study was performed to examine the effects of resistance training on SEVR and CAC in young men. A total of 28 young men were divided into 2 groups: control (n = 13) and training (n = 15). In the training group, subjects underwent supervised resistance training for 4 weeks (5 sets of 10 repetitions at 75% of 1-repetition maximum, 3 times/week). CAC and SEVR were then measured in all subjects. In the cross-sectional study, SEVR was significantly positively correlated with CAC, whereas resistance training significantly decreased both SEVR and CAC. Moreover, training-induced changes in CAC were significantly correlated with changes in SEVR. Thus, these results suggest that resistance training-induced decrease in CAC is associated with decreased SEVR in young men.
