Abstract

Some evidences indicate that the female sex hormones protect against the development of cardiovascular diseases. Modulation of sympathetic activity may be one of the possibilities. We investigated the influence of treadmill stress on blood pressure (BP) and plasma neuropeptide Y(NPY), norepinephrine (NE) and epinephrine (E) concentrations in 11 normotensive, menstruating women in the follicular (HWf) and luteal (HWl) phases and in eight ovariectomized women, before (OVX) and after estrogen supplementation (OVXe). Both at rest and during exercise there were no differences in BP between HWf and HWl and between OVX and OVXe. During stress BP was significantly lower in HWf and HWl than in OVX but not in OVXe. NPY did not differ significantly between the groups of women either at rest or during activity. We did not observe differences in resting and stimulated NE and E between HWf and HWl and betweenOVX and OVXe. Neither resting nor activated NE and E differed betweenthe groups, except higher stimulated NE in OVX than in HWf. These results suggest that the female sex hormones may modulate the BP responseto dynamic exercise. Our data support evidence that this influence may be exerted by circulating catecholamines and not by NPY. (C) 1998 Elsevier Science B.V. All rights reserved.
