Is arterial stiffness associated with running records in amateur marathoners?
Reduced arterial stiffness is associated with better running records in amateur marathoners, suggesting vascular function contributes to running capacity.

May link arterial stiffness to marathon performance in amateurs; hypothesis-generating and requires prospective confirmation before clinical relevance.
PURPOSE: Arterial stiffness is an independent predictor of cardiovascular risk and may contribute to reduced running capacity in humans. This study investigated the relationship between course record and arterial stiffness in marathoners who participated in the Seoul International Marathon in 2012. METHODS: A total of 30 amateur marathoners (Males n = 28, Females n = 2, mean age = 51.6 ± 8.3 years) were assessed before and after the marathon race. Brachial-ankle pulse wave velocity (ba-PWV) was assessed by VP-1000 plus (Omron Healthcare Co., Ltd., Kyoto, Japan) before and immediately after the marathon race. Pearson's correlation coefficient was used to determine the relationship between race record and ba-PWV. In addition, Wilcoxon signed rank test was used to determine the difference in ba-PWV between before and after the race. RESULTS: There was no significant change in the ba-PWV of marathoners before and after the race (1271.1 ± 185 vs. 1268.8 ± 200 cm/s, P=0.579). Both the full course record (Pearson's correlation coefficient = 0.416, P = 0.022) and the record of half line (Pearson's correlation coefficient = 0.482, P = 0.007) were positively related with the difference in ba-PWV, suggesting that reduced arterial stiffness is associated with a better running record in the marathon. CONCLUSION: These results may suggest that good vascular function contributes to a better running record in the marathon race.

Jung et al. (2014) conducted an observational in Healthy amateur marathoners (n=30). Full course marathon record was evaluated on Correlation between full course marathon record and difference in brachial-ankle pulse wave velocity (ba-PWV) (r = 0.416, p=0.022). A better full course marathon record was correlated with the difference in brachial-ankle pulse wave velocity, suggesting reduced arterial stiffness is associated with better running performance.
