Abstract

AbstractAim Assess the cardiac autonomic modulation during and after lower limbs resistance exercise (RE) in elderly compared to young.Methods Fifteen elderly (66 ± 5 years) and 15 young (25 ± 4 years) underwent a RE protocol on the Leg Press at 70% of one repetition maximum. Parasympathetic indices (LnSD1 and LnRMSSD) were obtained through ultra-short-term heart rate variability analyze at resting, peak, and recovery (1, 3, 5, 10, and 15 min); in addition, heart rate recovery (HRR) was obtained.Results At the peak effort: LnSD1 and LnRMSSD were higher in the elderly compared to young (LnSD1: 0.65 ± 0.21 vs. 0.44 ± 0.22, p < 0.05; LnRMSSD: 0.81 ± 0.21 vs. 0.58 ± 0.23, p < 0.05); and at recovery phase: attenuated HRR and lower parasympathetic response were found to elderly compared to young (p < 0.05).Conclusion At the peak of RE, greater parasympathetic modulation was observed in elderly compared to young, and during recovery lower parasympathetic modulation and attenuated HRR were found in elderly.Keywords: Agingautonomic nervous systemcardiovascular systemexercise Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingThe authors would like to thank the Fundação de Amparo à Pesquisa do Estado de São Paulo–FAPESP (2015/26501-1) and the Conselho Nacional de Desenvolvimento Científico e Tecnológico–CNPq (102489/2022-0) for their financial support, as well as the volunteers for their effort and enthusiastic cooperation throughout the study

健康老年人心脏自主调节和下肢阻力运动:一项横断面研究

摘要:比较老年人和年轻人在下肢阻力运动(RE)期间和之后的心脏自主调节。方法15例老年人(66±5岁)和15例年轻人(25±4岁)，以70%的最大重复率进行腿部按压。通过静息、峰值和恢复时(1、3、5、10和15 min)的超短期心率变异性分析获得副交感神经指数(LnSD1和LnRMSSD);此外，还获得了心率恢复(HRR)。结果在工作高峰期:老年人的LnSD1和LnRMSSD高于年轻人(LnSD1: 0.65±0.21比0.44±0.22,p < 0.05;LnRMSSD: 0.81±0.21∶0.58±0.23,p < 0.05);在恢复期，老年人的HRR和副交感神经反应明显低于年轻人(p < 0.05)。结论在RE高峰期，老年人副交感神经调节明显高于年轻人，在恢复过程中，老年人副交感神经调节较低，HRR减弱。关键词:衰老自主神经系统心血管系统运动披露声明作者未报告潜在利益冲突。作者想要感谢圣保罗健康基金会(2015/26501-1)和国家环境保护协会Científico e Tecnológico-CNPq(102489/2022-0)的资金支持，以及志愿者在整个研究过程中的努力和热情合作

期刊介绍： This comprehensive journal is recognized for its useful balance of research and clinical practice articles. For more than twenty five years Physical & Occupational Therapy in Geriatrics has functioned as a forum for allied health professionals as well as others with a focus on rehabilitation of the geriatric client to share information, clinical experience, research, and therapeutic practice. Each issue focuses on current practice and emerging issues in the care of the older client, including rehabilitation and long-term care in institutional and community settings, and innovative programming; the entire range of problems experienced by the elderly; and the current skills needed for working with older clients.
