Flexibility is associated with arterial distensibility. Many individuals involved in sport, exercise, and/or fitness perform self-myofascial release (SMR) using a foam roller, which restores muscles, tendons, ligaments, fascia, and/or soft-tissue extensibility. However, the effect of SMR on arterial stiffness and vascular endothelial function using a foam roller is unknown. This study investigates the acute effect of SMR using a foam roller on arterial stiffness and vascular endothelial function. Ten healthy young adults performed SMR and control (CON) trials on separate days in a randomized controlled crossover fashion. Brachial-ankle pulse wave velocity (baPWV), blood pressure, heart rate, and plasma nitric oxide (NO) concentration were measured before and 30 minutes after both SMR and CON trials. The participants performed SMR of the adductor, hamstrings, quadriceps, iliotibial band, and trapezius. Pressure was self-adjusted during myofascial release by applying body weight to the roller and using the hands and feet to offset weight as required. The roller was placed under the target tissue area, and the body was moved back and forth across the roller. In the CON trial, SMR was not performed. The baPWV significantly decreased (from 1,202 ± 105 to 1,074 ± 110 cm·s-1) and the plasma NO concentration significantly increased (from 20.4 ± 6.9 to 34.4 ± 17.2 μmol·L-1) after SMR using a foam roller (both p < 0.05), but neither significantly differed after CON trials. These results indicate that SMR using a foam roller reduces arterial stiffness and improves vascular endothelial function.
柔韧性与动脉扩张性相关。许多从事运动、锻炼和/或健身的人使用泡沫轴进行自我肌筋膜放松（SMR），这可恢复肌肉、肌腱、韧带、筋膜和/或软组织的伸展性。然而，使用泡沫轴进行SMR对动脉僵硬度和血管内皮功能的影响尚不清楚。本研究调查了使用泡沫轴进行SMR对动脉僵硬度和血管内皮功能的急性影响。10名健康的年轻成年人以随机对照交叉方式在不同日期进行了SMR和对照（CON）试验。在SMR和CON试验前及试验后30分钟测量肱踝脉搏波速度（baPWV）、血压、心率和血浆一氧化氮（NO）浓度。参与者对内收肌、腘绳肌、股四头肌、髂胫束和斜方肌进行了SMR。在肌筋膜放松过程中，通过将体重施加于泡沫轴并根据需要用手和脚来抵消重量，自行调节压力。将泡沫轴置于目标组织区域下方，身体在泡沫轴上来回移动。在CON试验中，未进行SMR。使用泡沫轴进行SMR后，baPWV显著降低（从1202±105降至1074±110 cm·s-1），血浆NO浓度显著升高（从20.4±6.9升至34.4±17.2 μmol·L-1）（均p<0.05），但CON试验后两者均无显著差异。这些结果表明，使用泡沫轴进行SMR可降低动脉僵硬度并改善血管内皮功能。
