The present study aimed at investigating the effects of a daily undulating periodization (DUP) and non-periodized (NP) resistance training programs on hemodynamic parameters of older women. Forty-two older women were randomized into one of the three experimental groups: NP, DUP, and control group (CG). Evaluations of the hemodynamic parameters occurred before, during and after the intervention. The exercise programs were performed twice a week over 22 weeks. NP and DUP groups were based on 3 sets of 8-10 repetitions in 9 exercises. In NP, the two exercise sessions were based on traditional strength training, which was performed at a Difficult intensity according to the rating of perceived exertion (RPE) method. In DUP, the first session was based on power resistance exercise, in which the concentric muscle contraction was performed as fast as possible at a moderate intensity based on RPE, while the second session was the same that was performed by NP. The findings demonstrated that diastolic blood pressure (90.4 vs. 76.2 mmHg) and mean arterial pressure (108.6 vs. 92.7 mmHg) were significantly reduced after NP, while no significant alterations were observed in DUP. Nevertheless, both training groups seem to have a cardio protective effect, since both training modes prevented the increase in HR reported in the experimental period in CG. In conclusion, our findings indicate that a 22-week NP resistance training program causes beneficial effects on hemodynamic parameters of older women. NCT03443375.
本研究旨在调查每日波动周期化（DUP）和非周期化（NP）抗阻训练计划对老年女性血流动力学参数的影响。42名老年女性被随机分为三个实验组之一：NP组、DUP组和对照组（CG）。在干预前、干预期间和干预后对血流动力学参数进行评估。运动计划每周进行两次，持续22周。NP组和DUP组基于9项练习，每组3组，每组8 - 10次重复。在NP组中，两次练习课程基于传统力量训练，根据主观用力程度（RPE）方法在困难强度下进行。在DUP组中，第一节基于爆发力抗阻训练，其中根据RPE在中等强度下尽可能快地进行向心性肌肉收缩，而第二节与NP组相同。研究结果表明，NP组训练后舒张压（90.4对76.2 mmHg）和平均动脉压（108.6对92.7 mmHg）显著降低，而DUP组未观察到显著变化。然而，两个训练组似乎都有心脏保护作用，因为两种训练模式都防止了CG组在实验期间报告的心率增加。总之，我们的研究结果表明，为期22周的NP抗阻训练计划对老年女性的血流动力学参数有有益影响。NCT03443375。
