The relationship between arterial stiffness and cardiorespiratory fitness in long-distance runners with exercise-induced hypertension has not been established. We assessed the relationship among exercise-induced hypertension, arterial stiffness, and cardiorespiratory fitness in long-distance runners.
Middle-aged men between 40 and 60 years of age were assigned to the following groups: normal blood pressure (N.=17), exercise-induced hypertension (N.=39), and undiagnosed complex hypertension (N.=10) using the graded exercise test. Arterial stiffness was evaluated with carotid-femoral pulse wave velocity and augmentation index.
The carotid-femoral pulse wave velocity was significantly higher in the complex hypertension group than in the normal blood pressure and exercise-induced hypertension groups (P<0.05); there was no difference in this variable between the normal blood pressure and exercise-induced hypertension groups. The complex hypertension group had a significantly higher augmentation index and augmentation index corrected by 75 beats/min than the exercise-induced hypertension and normal blood pressure groups (P<0.05), while the exercise-induced hypertension group had a higher augmentation index and augmentation index corrected by 75 beats/min than the normal blood pressure group (P<0.05). The maximal oxygen intake was negatively correlated with the peak systolic blood pressure during exercise (r=-0.267, P=0.030), pulse wave velocity (r=-0.246, P=0.048), augmentation index (r=-0.359, P=0.003), and augmentation index corrected by 75 beats/min (r=-0.369, P=0.002).
Given the known association of arterial stiffness with cardiovascular disease, runners with exercise-induced hypertension may have an increased risk of cardiovascular events. However, cardiorespiratory fitness correlated negatively with blood pressure and arterial stiffness, which would be beneficial for the vascular health of long-distance runners.
运动引起的高血压长跑运动员的动脉僵硬与心肺功能适应性之间的关系尚未确定。我们评估了长跑运动员中运动引起的高血压、动脉僵硬和心肺功能适应性之间的关系。
使用分级运动试验将 40 至 60 岁的中年男性分配到以下组：正常血压（N.=17）、运动引起的高血压（N.=39）和未确诊的复杂高血压（N.=10）。使用颈动脉-股动脉脉搏波速度和增强指数评估动脉僵硬。
复杂高血压组的颈动脉-股动脉脉搏波速度明显高于正常血压组和运动引起的高血压组（P<0.05）；正常血压组和运动引起的高血压组之间该变量无差异。复杂高血压组的增强指数和校正 75 次/分的增强指数明显高于运动引起的高血压组和正常血压组（P<0.05），而运动引起的高血压组的增强指数和校正 75 次/分的增强指数高于正常血压组（P<0.05）。最大摄氧量与运动时的收缩压峰值（r=-0.267，P=0.030）、脉搏波速度（r=-0.246，P=0.048）、增强指数（r=-0.359，P=0.003）和校正 75 次/分的增强指数（r=-0.369，P=0.002）呈负相关。
鉴于动脉僵硬与心血管疾病的已知关联，运动引起的高血压的跑步者可能有更高的心血管事件风险。然而，心肺功能适应性与血压和动脉僵硬呈负相关，这将有利于长跑运动员的血管健康。
