Higher maximal oxygen uptake in endurance-trained athletes is significantly associated with lower central (r=-0.510, P=0.018) and peripheral (r=-0.472, P=0.031) arterial stiffness.

Is peripheral arterial stiffness associated with maximal oxygen uptake in endurance-trained athletes?
Higher maximal oxygen uptake is associated with lower peripheral and central arterial stiffness in endurance-trained athletes.
Effect estimate: r=-0.510 (central) and r=-0.472 (peripheral)
p-value: P=0.018 (central) and P=0.031 (peripheral)
Abstract Increased central arterial stiffness is associated with decreased maximal oxygen uptake (V̇O2max). Endurance exercise training improves arterial function throughout the whole body, but the relationship between central and peripheral arterial stiffness and V̇O2max is unknown. The present study investigated the relationship between central and peripheral arterial stiffness and V̇O2max in endurance-trained athletes. Twenty-one young male endurance-trained athletes and 12 sedentary controls were included in this study. Resting values for carotid-femoral velocity and femoral-ankle pulse wave velocity were obtained to assess central and peripheral arterial stiffness, respectively. V̇O2max was obtained by incremental cycle ergometer testing. Both carotid-femoral pulse wave velocity (P=0.019) and femoral-ankle pulse wave velocity (P=0.028) were lower in athletes than in controls. V̇O2max was significantly higher in athletes compared to controls (P<0.001). Significant correlations were found between carotid-femoral pulse wave velocity and V̇O2max (r=–0.510, P=0.018) and between femoral-ankle pulse wave velocity and V̇O2max (r=–0.472, P=0.031) in athletes. However, no correlations were evident in controls. These results suggest that higher V̇O2max is associated with lower peripheral arterial stiffness in addition to central arterial stiffness among endurance-trained athletes.
Hashimoto et al. (2023) conducted a cross-sectional in Healthy (n=33). Endurance training vs. Sedentary controls was evaluated on Correlation between arterial stiffness and V̇O2max (r=-0.510 (central) and r=-0.472 (peripheral), p=P=0.018 (central) and P=0.031 (peripheral)). Higher maximal oxygen uptake in endurance-trained athletes is significantly associated with lower central (r=-0.510, P=0.018) and peripheral (r=-0.472, P=0.031) arterial stiffness.
