Abstract

Background: Evidence on the effectiveness of combined exercise over aerobic exercise alone in lowering blood pressure (BP) remains limited. This study compared the effectiveness of combined aerobic plus resistance training versus aerobic training alone, with both interventions matched for exercise duration.

Methods: This randomized controlled trial included thirty-one female participants eligible for final analysis. Participants were randomly assigned to two groups: 15 to the Control (C) group, which underwent 8 weeks of aerobics, and 16 to the Combined Training (CT) group, which underwent 8 weeks of combined training. Outcome measures included weight, height, Body Mass Index (BMI), systolic and diastolic blood pressure (SBP and DBP), heart rate (HR), mean arterial pressure (MAP), pulse pressure (PP), hand grip strength (HGS), and performance on the 30-second Chair Stand Test (30-s CST). These variables were assessed at baseline and at the end of week 8. Two-way ANOVA followed Tukey post-hoc was applied to analyze changes within and between groups over time. The effect size was calculated using partial eta squared (ηp2).

Results: Baseline characteristics were similar across groups, except for heart rate. Both groups showed significant reductions in SBP and DBP after the intervention ([C: SBP decreased by -7.4±2.2, P=0.00; DBP decreased by -5.1±2.4, P=0.00] [CT: SBP decreased by -6.1±2.1, P<0.01, and DBP decreased by -6.9±2.0, P<0.01]). The reduction in SBP was more pronounced in the C than in the CT (P=0.04), while the reduction in DBP was greater in the CT group (P=0.04). An improvement in the outcome variable is caused by the "group" or "time" effect but not by the effect of "group × time."

Conclusions: Adding resistance training to aerobic exercise enhances the reduction in diastolic blood pressure compared to aerobic exercise alone in prehypertension middle-aged women.

比较联合运动和有氧运动对高血压前期女性血压的影响:一项随机对照试验。
背景:联合运动比单独有氧运动在降低血压(BP)方面的有效性证据仍然有限。这项研究比较了有氧加阻力训练与单独有氧训练的效果,两种干预措施的运动时间相匹配。方法:本随机对照试验纳入31名符合最终分析条件的女性受试者。参与者被随机分为两组:对照组(C) 15人,进行8周的有氧运动;联合训练组(CT) 16人,进行8周的联合训练。结果测量包括体重、身高、身体质量指数(BMI)、收缩压和舒张压(SBP和DBP)、心率(HR)、平均动脉压(MAP)、脉压(PP)、握力(HGS)以及30秒椅子站立测试(30-s CST)的表现。在基线和第8周结束时对这些变量进行评估。采用双向方差分析,分析组内和组间随时间的变化。效应大小用偏eta平方(ηp2)计算。结果:各组基线特征相似,心率除外。两组干预后收缩压和舒张压均显著降低([C]:收缩压下降-7.4±2.2,P=0.00;舒张压下降-5.1±2.4,P=0.00] [CT:收缩压下降-6.1±2.1,P]结论:与单纯有氧运动相比,有氧运动中加入阻力训练能促进高血压前期中年妇女舒张压的降低。
