Abstract

Abstract There is inconclusive evidence concerning the effects of routine participation in ultra-endurance events on cardiovascular disease (CVD) risk. Arterial compliance is a reliable, non-invasive, and effective tool for evaluating CVD risk. The purpose of this research was to examine if race length influences acute changes in arterial compliance following an ultra-marathon event. A total of 46 ultra-marathon runners were recruited including 21 participants (39.8 ± 8.3 years, 6 females) in the 80-km event and 25 participants (43.7 ± 9.8 years, 3 female) in the 195-km event. Arterial compliance was measured via radial applanation tonometry (CR-2000, HDI) for diastolic pulse contour analysis before and following the race. Significant between-group differences were found for changes in large arterial compliance with a decrease (increase in stiffness) following the 195-km event and an increase following the 80-kilometre event (p < .05). Longer race lengths are associated with greater reductions in large arterial compliance following recreational ultra-marathon running. Assessment of arterial compliance might be a useful prognostic tool to assess the long-term risk of CVD among ultra-marathon runners.

超长耐力马拉松后比赛长度对动脉顺应性的影响

关于常规参加超耐力赛事对心血管疾病(CVD)风险的影响，尚无确凿证据。动脉顺应性是评估心血管疾病风险的可靠、无创和有效的工具。本研究的目的是检查比赛长度是否影响超级马拉松赛事后动脉顺应性的急性变化。共招募了46名超级马拉松运动员，其中80公里项目21名(39.8±8.3岁，6名女性)，195公里项目25名(43.7±9.8岁，3名女性)。通过桡动脉压度计(CR-2000, HDI)测量动脉顺应性，用于赛前和赛后舒张脉搏轮廓分析。在195公里事件后大动脉顺应性降低(僵硬度增加)和80公里事件后增加的变化组间差异显著(p < 0.05)。较长的比赛长度与休闲超马拉松后大动脉顺应性的更大降低有关。动脉顺应性评估可能是评估超级马拉松运动员心血管疾病长期风险的有用预后工具。
