Abstract

This study explored the impact of a 16-week high-speed resistance training (HSRT) program on heart rate variability (HRV) indices in independent older adults. The participants were divided into either an intervention group (IG, N = 40) or a control group (CG, N = 39). The IG participated in supervised HSRT sessions three times weekly, comprising 5-6 exercises with 2-3 sets and 6-10 repetitions, which lasted 60-70 min. The CG did not engage in any exercise program. HRV indices, encompassing time, frequency, and non-linear, were recorded over a six-minute period. The ANCOVA results revealed significant improvements favoring the IG for mean RR (η²_p = 0.050), systolic blood pressure (η²_p = 0.126), and pulse pressure (η²_p = 0.157). Additionally, within-group analyses revealed significant increases in stress index (d_unb = 0.52), sample entropy (d_unb = 0.38), and DFA α1 (d_unb = 0.38) exclusively in the CG. This study highlights the significant potential of the HSRT to induce favorable changes in parasympathetic activity and reduce arterial stiffness.

16周高速抗阻训练计划对社区独立老年人心率变异性指标的影响：一项临床试验。

本研究探讨了16周高速阻力训练（HSRT）计划对独立老年人心率变异性（HRV）指数的影响。参与者被分为干预组（IG, N = 40）和对照组（CG, N = 39）。IG每周参加3次有监督的HSRT，包括5-6次练习，2-3组，重复6-10次，每次持续60-70分钟。CG不参加任何锻炼计划。在6分钟的时间内记录HRV指数，包括时间、频率和非线性。ANCOVA结果显示，IG在平均RR （η2p = 0.050）、收缩压（η2p = 0.126）和脉压（η2p = 0.157）方面均有显著改善。此外，组内分析显示，CG组的应激指数（dunb = 0.52）、样本熵（dunb = 0.38）和DFA α1 （dunb = 0.38）均显著升高。这项研究强调了HSRT在诱导副交感神经活动的有利变化和降低动脉僵硬方面的显著潜力。

期刊介绍： The Journal of Applied Gerontology (JAG) is the official journal of the Southern Gerontological Society. It features articles that focus on research applications intended to improve the quality of life of older persons or to enhance our understanding of age-related issues that will eventually lead to such outcomes. We construe application broadly and encourage contributions across a range of applications toward those foci, including interventions, methodology, policy, and theory. Manuscripts from all disciplines represented in gerontology are welcome. Because the circulation and intended audience of JAG is global, contributions from international authors are encouraged.
