Peripheral Arterial Stiffness is Associated with Maximal Oxygen Uptake in Athletes
Int J Sports Med DOI: 10.1055/a-2053-7613Increased 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 V̇...
