Effect of resistance training on arterial wave reflection and brachial artery reactivity in normotensive postmenopausal women

摘要: Large elastic artery stiffness increases with age and menopause is a mitigating factor in women. High-intensity resistance training (RT) arterial young men However, the effects of moderate intensity RT on central aortic pressure wave reflection healthy postmenopausal women are unknown. Healthy sedentary normotensive were randomly assigned to either 18 weeks (2 days/week) (RES n = 13) or aerobic (AER 10). Central brachial reactivity assessed before after training. was evaluated by measuring augmentation index (AIa) round trip travel time (Δtp) reflected using applanation tonometry. Brachial flow mediated dilation (FMD). Eighteen did not change AIa (28.9 ± 1.9 vs. 28.5 1.9%; mean S.E.M.) Δtp (140.6 2.4 141.2 2.1 ms). In contrast, AER group showed decrease from 28.8 25.1 1.4% (P < 0.05) an increase 137.3 2.5 144.6 2.9 ms 0.05). FMD significantly following This prospective, randomized study demonstrated that whole body previously sedentary, does alter reflection.
