Key result
Running a 195-km ultra-marathon was associated with a significant decrease in large arterial compliance compared to an increase following an 80-km event (p < .05).
Why the study?
Does race length influence acute changes in arterial compliance following an ultra-marathon event in recreational runners?
Observational (n=46)

p-value: p=<.05
Longer ultra-marathon race lengths (195-km vs 80-km) are associated with greater acute reductions in large arterial compliance, suggesting a potential increase in cardiovascular risk.
Longer ultra-marathons were associated with reduced arterial compliance; hypothesis-generating for CV risk and requires prospective validation.
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.
