There is little research about the effects of ultra-endurance exercise on arterial morphological and functional properties. The aim was to assess the acute changes of the carotid-femoral pulse wave velocity and carotid doppler-derived parameters following an ultra-marathon race as well as the intima-media thickness of the carotid artery in ultra-marathon runners. Twenty athletes were examined at baseline and within 10 mins after a 246 km running race. Measurements included carotid-femoral pulse wave velocity, peak-systolic and end-diastolic velocities of carotid artery blood flow, pulsatility and resistivity indices and blood biochemical parameters. The intima-media thickness of the right and left carotid artery was measured before the race. Arterial stiffness and carotid artery intima media thickness at rest remained within known normal limits. The ultra-marathon race significantly increased carotid-femoral pulse wave velocity by 22.6% and pulsatility index by 10.2%. There was a decrease in body weight by 3.35% and an increase of all biochemical markers of muscle damage after the race. Additionally, C-reactive protein was correlated with both pulsatility and resistivity indices post-race. This study shows that immediately after a 246 km ultra-marathon running race, acute increase of arterial stiffness and vascular resistance were evident. The carotid artery thickness of ultra-marathon runners was within normal range.
关于超耐力运动对动脉形态和功能特性的影响的研究甚少。本研究旨在评估超马拉松比赛后颈动脉-股动脉脉搏波速度和颈动脉多普勒衍生参数的急性变化，以及超马拉松运动员的颈动脉内-中膜厚度。20 名运动员在基线时和 246 公里跑步比赛后 10 分钟内接受了检查。测量包括颈动脉-股动脉脉搏波速度、颈动脉血流的收缩期峰值和舒张末期速度、搏动指数和阻力指数以及血液生化参数。在比赛前测量了右侧和左侧颈动脉的内-中膜厚度。动脉僵硬度和休息时颈动脉内-中膜厚度仍在已知的正常范围内。超马拉松比赛使颈动脉-股动脉脉搏波速度显著增加了 22.6%，搏动指数增加了 10.2%。比赛后体重下降了 3.35%，所有肌肉损伤的生化标志物都增加了。此外，C 反应蛋白与赛后搏动指数和阻力指数呈正相关。这项研究表明，在 246 公里超长马拉松比赛后，动脉僵硬度和血管阻力的急性增加是明显的。超马拉松运动员的颈动脉厚度在正常范围内。
