Factors associated with the menstrual cycle, such as the endogenous hormones estrogen and progesterone, have dramatic effects on cardiovascular regulation. It is unknown how this affects postexercise hemodynamics. Therefore, we examined the effects of the menstrual cycle and sex on postexercise hemodynamics. We studied fourteen normally menstruating women [24.0 (4.2) yr] and 14 men [22.5 (3.5) yr] before and through 90 min after cycling at 60% VO_2peak for 60 min. Women were studied during their early follicular, ovulatory, and mid-luteal phases; men were studied once. In men and women during all phases studied, mean arterial pressure was decreased following exercise throughout 60 min (P 0.001) postexercise and returned to preexercise values at 90 min (P = 0.089) postexercise, systemic vascular conductance was increased following exercise in throughout 60 min (P = 0.005) postexercise and tended to be elevated at 90 min postexercise (P = 0.052), and femoral vascular conductance was increased following exercise throughout 90 min (P 0.001) postexercise. Menstrual phase and sex had no effect on the percent reduction in arterial pressure (P = 0.360), the percent rise in systemic vascular conductance (P = 0.573), and the percent rise in femoral vascular conductance (P = 0.828) from before to after exercise, nor did the pattern of these responses differ across recovery with phase or sex. This suggests that postexercise hemodynamics are largely unaffected by sex or factors associated with the menstrual cycle.
