Description
Summary:Almost all scientific research that investigates how exercise training affects the circulatory system estimates main arteries, like brachial artery and few focus on the cutaneous microvascular function. The aim of this study was to estimate the impact of 25 Programmed Aerobic/Anaerobic/Accommodating Circuit Exercise (PACE) training sessions on changes in vasomotor reactions (microvascular beds of the skin) in healthy untrained women. PACE training is a short duration (∼30 min), intense physical activity that includes both aerobic and anaerobic states, that changes after every 30 s. 20 women participated in this study (age 35±10 years; body mass index 26.7±4.2). The laser Doppler flow technique (MoorLDI2) was used to estimate the regional blood flow changes on the upper part of the palm induced by local acetylcholine (1% Ach) and sodium nitroprusside (1% SNP) iontophoresis; assessment of concentrations of C reactive protein and cortisol were made with the Immulite 2500. There was an increase in endothelium-dependent vasodilatation after 25 PACE training sessions, that was estimated by laser dopplerography test with 1% Ach iontophoresis (292±80 PU vs 335±88 PU, p
