Objective:The aim of the study was to evaluate if there are differences in endothelial function before and after acute exercise in women at different menopausal stages with high and low cardiorespiratory fitness.Methods:Participants were healthy high-fit premenopausal (n = 11), perimenopausal (n = 12), and postmenopausal women (n = 13) and low-fit perimenopausal (n = 7) and postmenopausal women (n = 8). Brachial artery flow-mediated dilation (FMD) was measured before and after acute moderate intensity exercise. FMD was calculated as (Diameterpeak-Diameterbaseline)/ Diameterbaseline) × 100. Differences between high-fit women and between high- and low-fit perimenopausal and postmenopausal women were assessed with repeated-measure …

Circulating angiogenic cells (CAC) influence vascular repair through the secretion of proangiogenic factors and cytokines. While CAC are deficient in patients with diabetes and exercise has a beneficial effect on CACs, the impact of these factors on paracrine secretion from CAC is unknown. We aimed to determine whether the in vitro secretion of selected cytokines and nitric oxide (NO) from CAC is influenced by hyperglycemia and acute exercise. Colonyforming unit CAC (CFU-CAC) were cultured from young active men (n = 9, 24 ± 2 years) at rest and after exercise under normal (5 mmol/L) and elevated (15 mmol/L) glucose. Preliminary …

Endothelial dysfunction and inflammation are characteristics of subclinical atherosclerosis and may increase through progressive menopausal stages. Evaluating endothelial responses to acute exercise can reveal underlying dysfunction not apparent in resting conditions. The purpose of this study was to investigate markers of endothelial function and inflammation before and after acute exercise in healthy low-active perimenopausal (PERI) and late postmenopausal (POST) women. Flow-mediated dilation (FMD), CD31+/CD42b- and CD62E+ endothelial microparticles (EMPs), and the circulating inflammatory factors monocyte chemoattractant protein 1 (MCP-1), interleukin 8 (IL-8), and tumor necrosis factor-α (TNF-α) were measured before and 30 min after acute exercise. Before exercise, FMD was …
