Exercise training for 12 weeks lowered diastolic blood pressure, sICAM-1, sVCAM-1, and endothelin-1 in both premenopausal and recently postmenopausal women.
Does 12 weeks of exercise training improve biomarkers of vascular function in premenopausal and recent postmenopausal women?
Exercise training improves vascular biomarker profiles in both premenopausal and recently postmenopausal women, counteracting early menopause-related vascular decline.
Menopause is associated with an accelerated decline in vascular function; however, whether this is an effect of age and/or menopause and how exercise training may affect this decline remains unclear. We examined a range of molecular measures related to vascular function in matched premenopausal and postmenopausal women before and after 12 wk of exercise training. Thirteen premenopausal and 10 recently postmenopausal 1.6 ± 0.3 (means ± SE) years after final menstrual period women only separated by 3 yr (48 ± 1 vs. 51 ± 1 yr) were included. Before training, diastolic blood pressure, soluble intercellular adhesion molecule-1 (sICAM-1), and skeletal muscle expression of thromboxane A synthase were higher in the postmenopausal women compared with the premenopausal women, all indicative of impaired vascular function. In both groups, exercise training lowered diastolic blood pressure, the levels of sICAM-1, soluble vascular adhesion molecule-1 (sVCAM-1), as well as plasma and skeletal muscle endothelin-1. The vasodilator prostacyclin tended (P = 0.061) to be higher in plasma with training in the postmenopausal women only. These findings demonstrate that already within the first years after menopause, several biomarkers of vascular function are adversely altered, indicating that these biomarker changes are more related to hormonal changes than aging. Exercise training appears to have a positive impact on vascular function, as indicated by a marked improvement in the biomarker profile, in both premenopausal and postmenopausal women.
Nyberg et al. (Thu,) conducted a other in Menopause (n=23). Exercise training vs. Baseline (before training) was evaluated on Biomarkers of vascular function (diastolic blood pressure, sICAM-1, sVCAM-1, endothelin-1). Exercise training for 12 weeks lowered diastolic blood pressure, sICAM-1, sVCAM-1, and endothelin-1 in both premenopausal and recently postmenopausal women.
