Ultra-marathon running participation has become increasingly more popular in recent years; however, there is inconclusive evidence concerning the effects of participation on cognition and cardiovascular function. The purpose of this study was to examine alterations in cardiovascular function and cognitive performance and their association in ultra-marathon runners prior to and following an ultra-endurance event.
In total, 24 runners (19 males and 5 females) participated in an ultra-marathon race (FatDog120) held in British Columbia, Canada. Participants competed in varying races distances [48 km ( = 2), 80 km ( = 7), 113 km ( = 3), and 193 km ( = 12)]. Cognition was assessed prior to and upon race completion using simple reaction time, choice reaction time, discrimination reaction time, and recognition memory (% correct). Cardiovascular function was assessed prior to and upon race completion using radial applanation tonometry for diastolic pulse contour examination.
Cognitive performance displayed significantly ( < 0.001) slower reaction times post-race for simple (30.2%), discrimination (22.7%), and choice reaction time (30.5%), as well as a significant ( < 0.05) reduction in memory test performance (-8.2%). A significant association between systemic vascular resistance and choice reaction time was observed post-race ( = 0.41, < 0.05). Significant changes in post-race cardiovascular function were observed in resting heart rate (31.5%), cardiac output (27.5%), mean arterial blood pressure (-5.6%), total systemic resistance (-17.6%), systolic blood pressure (-7.0%), pulse pressure (-11.2%), and rate pressure product (22.4%). There was evidence of enhanced cardiovascular function being associated with improved cognitive performance before and after the ultra-endurance event.
Ultra endurance running is associated with marked impairments in cognitive performance that are associated (at least in part) with changes in cardiovascular function in healthy adults.
近年来，超级马拉松跑步参与度越来越高；然而，关于参与超级马拉松对认知和心血管功能的影响，证据尚无定论。本研究的目的是检查超级耐力赛事前后超级马拉松跑者的心血管功能和认知表现的变化及其关联。
共有24名跑步者（19名男性和5名女性）参加了在加拿大不列颠哥伦比亚省举行的超级马拉松比赛（FatDog120）。参与者参加了不同的比赛距离[48公里（=2人）、80公里（=7人）、113公里（=3人）和193公里（=12人）]。在比赛前和比赛结束时使用简单反应时间、选择反应时间、辨别反应时间和识别记忆（正确百分比）来评估认知。在比赛前和比赛结束时使用桡动脉压平式眼压计进行舒张期脉搏轮廓检查来评估心血管功能。
比赛后，认知表现显示简单反应时间（30.2%）、辨别反应时间（22.7%）和选择反应时间（30.5%）显著变慢（<0.001），记忆测试表现也显著下降（<0.05）（-8.2%）。比赛后观察到全身血管阻力与选择反应时间之间存在显著关联（=0.41，<0.05）。比赛后心血管功能在静息心率（31.5%）、心输出量（27.5%）、平均动脉血压（-5.6%）、总全身阻力（-17.6%）、收缩压（-7.0%）、脉压（-11.2%）和心率血压乘积（22.4%）方面有显著变化。有证据表明，在超级耐力赛事前后，心血管功能增强与认知表现改善有关。
超级耐力跑与健康成年人认知表现的显著受损有关，这种受损（至少部分）与心血管功能变化有关。
