Postmenopausal women exhibit elevated brachial-ankle pulse wave velocity (baPWV), an indicator of arterial stiffness, which is associated with an increased risk of cardiovascular events and mortality. The purpose of this study is to examine the impact of combined resistance and aerobic exercise training on baPWV, blood pressure (BP), and cardiovascular fitness in postmenopausal women with stage 1 hypertension.
Twenty postmenopausal women (age, 75 ± 2 y; systolic BP, 152 ± 2 mm Hg, diastolic BP, 95 ± 3 mm Hg) were randomly assigned to a "no-exercise" (CON, n = 10) or combined exercise (EX, n = 10) group. The EX group performed resistance and aerobic exercise for 12 weeks, 3 times per week. Exercise intensity was increased gradually, from 40% to 70% of heart rate reserve, every 4 weeks. BaPWV, BP, blood nitrite/nitrate, endothelin-1 (ET-1), cardiovascular fitness, and body composition were measured before and after the 12-week intervention.
BP, baPWV (-1.2 ± 0.4 m/s), ET-1 (-2.7 ± 0.3 μmol/mL), nitrite/nitrate (+4.5 ± 0.5 μM), functional capacity, and body composition were significantly improved (P < 0.05) in the EX group after 12 weeks of training, but no changes were observed in the CON group.
These findings indicate that 12 weeks of combined exercise training improves arterial stiffness, BP, ET-1, blood nitrite/nitrate, functional capacity, and body composition in postmenopausal women with stage 1 hypertension. Thus, this study provides evidence that combined exercise training is a useful therapeutic method to improve cardiovascular health which can reduce cardiovascular disease risk in postmenopausal women with hypertension.
绝经后女性的肱踝脉搏波速度(baPWV)升高,这是动脉僵硬度的一个指标,与心血管事件风险和死亡率增加相关。本研究的目的是探讨阻力训练与有氧运动训练相结合对1期高血压绝经后女性的baPWV、血压(BP)和心血管健康状况的影响。
20名绝经后女性(年龄75±2岁;收缩压152±2 mmHg,舒张压95±3 mmHg)被随机分为“不运动”组(CON,n = 10)或联合运动组(EX,n = 10)。EX组进行阻力训练和有氧运动,为期12周,每周3次。运动强度每4周从心率储备的40%逐渐增加到70%。在为期12周的干预前后,测量baPWV、BP、血中亚硝酸盐/硝酸盐、内皮素-1(ET-1)、心血管健康状况和身体成分。
训练12周后,EX组的BP、baPWV(-1.2±0.4 m/s)、ET-1(-2.7±0.3 μmol/mL)、亚硝酸盐/硝酸盐(+4.5±0.5 μM)、功能能力和身体成分均有显著改善(P<0.05),而CON组未观察到变化。
这些研究结果表明,12周的联合运动训练可改善1期高血压绝经后女性的动脉僵硬度、BP、ET-1、血中亚硝酸盐/硝酸盐、功能能力和身体成分。因此,本研究提供了证据,表明联合运动训练是一种有益的治疗方法,可改善心血管健康,降低高血压绝经后女性的心血管疾病风险。
