Submaximal endurance training caused a temporary increase in arterial stiffness and pulse wave velocity (P<.001) in healthy runners, followed by a drop below baseline 30 minutes post-workout.

Does vigorous running alter arterial stiffness in healthy middle- and long-distance runners?
Vigorous endurance exercise causes a transient increase in arterial stiffness that drops below baseline levels during the recovery period in healthy runners.
p-value: p=<.001
Measures of arterial stiffness are indicators for cardiovascular health and predictors of cardiovascular events. Arterial stiffness is responsive to acute physiologic stressors such as exercise. However, the acute effects of intensive exercise and recovery on arterial stiffness are controversial. Thirty-seven healthy middle- and long-distance runners (33 men, mean age 26.5±6.6 years) underwent evaluation of their cardiovascular stiffness at rest, after a 15-minute warm-up, immediately after vigorous running 3 km at the pace of their 10-km personal best, and finally 30 minutes after terminating their workout. Peripheral and central systolic blood pressure, as well as augmentation index and pulse wave velocity (PWV), increased during exercise in comparison to baseline (P<.001, general linear model). Thirty minutes after terminating the workout, a drop in peripheral blood pressure (P<.001), central blood pressure (P<.001), and PWV (P=.001) below baseline was observed. Therefore, the authors found that exercise of either moderate or vigorous intensity causes a temporary increase in arterial stiffness in middle- and long-distance runners.
Müller et al. (Mon,) conducted a observational in Healthy middle- and long-distance runners (n=37). Submaximal endurance training vs. Baseline (rest) was evaluated on Arterial stiffness (peripheral and central systolic blood pressure, augmentation index, and pulse wave velocity) (p=<.001). Submaximal endurance training caused a temporary increase in arterial stiffness and pulse wave velocity (P<.001) in healthy runners, followed by a drop below baseline 30 minutes post-workout.
