Abstract

Are women more susceptible to acute postexercise orthostatic hypotension compared with men? We hypothesized that decreases in arterial pressure during recovery from dynamic exercise are greater in women compared with men. We studied 8 men and 11 women during inactive and active recovery from cycling exercise. Heart rate, stroke volume (SV), cardiac output, mean arterial pressure (MAP), and total peripheral resistance (TPR) were measured during and after 3 min of exercise at 60% of calculated maximum heart rate. At 1 min after exercise, MAP decreased less (P < 0.05) during inactive recovery in men (-18 ± 2 mmHg) compared with women (-30 ± 2 mmHg). This difference was due to greater decreases in SV and less increase in TPR during inactive recovery from exercise in women compared with men. These differences persisted for 5 min after exercise. MAP decreased less during active recovery in men compared with women. These findings suggest that women may have increased risk of postexercise orthostatic hypotension and that active recovery from exercise may reduce this risk.
