Abstract

Objective: There are sex differences in resting central pulse wave velocity (cPWV) but it is unclear if there are sex differences in the response to exercise. We evaluated potential sex differences of two measures of arterial stiffness and central pressures before and following maximal exercise.

Methods: We compared aortic and carotid systolic blood pressure (SBP), carotid β-stiffness and cPWV at rest, 15 minutes and 30 minutes following peak aerobic exercise in 73 participants (age=24 yrs; male n=34, female n=39).

Results: Women had lower aortic SBP, carotid SBP and CPWV, but similar carotid β-stiffness as men. Aortic SBP did not change, but carotid SBP and carotid β-stiffness increased 15 min post exercise (p<0.05) and returned to baseline at 30 min post exercise in both men and women. cPWV was unchanged with exercise in women, but decreased 30 min post exercise in men (p<0.05). These sex differences were unchanged when the data were corrected for differences in resting BP.

Conclusions: Resting cPWV and the cPWV response to exercise differ between men and women, without any sex differences in carotid stiffness. This suggests that sex may affect arterial stiffness differently in different arterial segments. Furthermore, the central BP response to exercise differs between the aorta and carotid arteries, in both men and women, suggesting the BP response to exercise is dependent on the arterial segment where it is measured.
