Effects of acute sympathetic activation on the central artery stiffness after strenuous endurance exercise

ConclusionThe baseline aPWV assessed 7 to 8  min after a strenuous half-marathon is similar to that pre-race in healthy runners. This agrees with previous studies suggesting CAS being at or below resting values >  5 min following completion of aerobic exercises. The same sympathetic stressor augments CAS to a greater extent 8–10 min post-race than pre-race, suggesting a greater post-exercise stiffening of central artery segments triggered by the same task.
