Exercise is a critical factor that impacts arterial stiffness. In this narrative review, we noted multiple findings that could not be reconciled with one another. Some studies indicated that arterial stiffness increases after a regimen of resistance training. However, such studies were limited by a lack of specification of the resistance training protocols, as well as varying results reported from different areas of the body, undermining the internal validity of the studies. Another factor explored in this review was how the order of performing exercises can affect arterial stiffness. Low-intensity resistance training before high-intensity resistance training resulted in increased arterial stiffness, whereas vice versa showed no change in arterial stiffness. Other studies indicated that resistance exercise results in reduced arterial stiffness. Intensity is a variable in studies that produces inconsistent results of arterial stiffness, with some studies suggesting high-intensity resistance training increases arterial stiffness and low-intensity resistance training decreases arterial stiffness, while other studies pointing to a significant decrease in arterial stiffness, regardless of the intensity of resistance training. Demographic factors such as gender, age, and diet play an important role in explaining these differences. In terms of future implications, there is potential clinical significance as increased arterial stiffness serves as a prognostic marker in diagnosing coronary heart disease.
运动是影响动脉僵硬度的一个关键因素。在这篇叙述性综述中，我们注意到多个相互矛盾的研究结果。一些研究表明，进行一段时间的阻力训练后动脉僵硬度会增加。然而，此类研究存在局限性，缺乏对阻力训练方案的具体说明，且身体不同部位报告的结果各异，这削弱了研究的内部效度。本综述探讨的另一个因素是运动执行顺序如何影响动脉僵硬度。在高强度阻力训练之前进行低强度阻力训练会导致动脉僵硬度增加，反之则动脉僵硬度无变化。其他研究表明，阻力运动可降低动脉僵硬度。强度是研究中的一个变量，其导致动脉僵硬度的结果不一致，一些研究表明高强度阻力训练会增加动脉僵硬度，低强度阻力训练会降低动脉僵硬度，而其他研究则指出，无论阻力训练强度如何，动脉僵硬度都会显著降低。性别、年龄和饮食等人口统计学因素在解释这些差异方面起着重要作用。就未来意义而言，增加的动脉僵硬度作为诊断冠心病的预后标志物具有潜在临床意义。
