A large part of the literature synthesis and conceptual framework outlined here has been published in the following peer-reviewed article Nùñez-Lisboa et al., 2023. Unraveling agerelated impairment of the neuromuscular system: exploring biomechanical and neurophysiological perspectives. Frontiers in Physiology, 14. This paper is available as a Supplementary Chapter II (see page 163-175) This publication was written during the initial phase of the PhD project to consolidate the existing knowledge in the field and identify key research gaps that the present thesis addresses. While some sections of the current introduction build upon that publication, the content has been revised and adapted to reflect the specific context, objectives, and scope of the thesis.enAtribución-NoComercial-CompartirIgual 3.0 Chile (CC BY-NC-SA 3.0 CL)NEUROMECÁNICAMARCHA HUMANA -- ASPECTOS FISIOLÓGICOSTERAPIA POR ESTIMULACIÓN ELÉCTRICAANCIANOS -- EJERCICIOThesisDewolf, Arthur prof. guíaCancino, Jorge prof. guía
