We propose\n                    <jats:italic>bioenergetic impedance<\/jats:italic>\n                    as a Network Physiology construct describing the time-dependent constraint on energetic throughput and recovery that arises when energetic pressure exceeds available biological capacity. Resistance, delay, congestion, and buffering burden may reflect mechanisms or manifestations of this mismatch, whereas compensatory rerouting may represent an adaptive response to constrained throughput. At the cellular level, substrate congestion and redox backpressure provide plausible mechanistic anchors, while metabolic rerouting and mitochondrial stress signaling may represent compensatory or signaling responses through which local energetic constraints may be accommodated or communicated. Their physiological consequence depends critically on reversibility. In\n                    <jats:italic>adaptive impedance cycling<\/jats:italic>\n                    , challenges that transiently exceed available capacity produce impedance followed by recovery, restoration or adaptive recalibration of flexible cross-system organization, and potentially expanded reserve. In\n                    <jats:italic>impedance lock-in<\/jats:italic>\n                    , repeated or unresolved challenge produces incomplete recovery, persistent residual constraint, compensatory allocation, reduced network flexibility, and constrained adaptive reserve. The framework therefore places recovery dynamics at the center of resilience and generates a testable prediction: adaptive states should show temporary, context-appropriate reconfiguration of cross-system interactions followed by restoration of flexible network organization, whereas maladaptive states should show incomplete recovery and persistent or functionally inappropriate network reconfiguration. Bioenergetic impedance thus provides a systems-level framework linking cellular energetic constraints with stress adaptation, maladaptation, and recovery across physiological networks.\n                  <\/jats:p>","DOI":"10.3389\/fnetp.2026.1967461","type":"journal-article","created":{"date-parts":[[2026,9,29]],"date-time":"2026-09-29T05:49:59Z","timestamp":1790660999000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["Bioenergetic impedance: a network physiology framework for stress adaptation, maladaptation, and recovery"],"prefix":"10.3389","volume":"6","author":[{"given":"Torsak","family":"Tippairote","sequence":"first","affiliation":[{"name":"Department of Life and Consumer Sciences, University of South Africa","place":["Pretoria, South Africa"]},{"name":"HP Medical Center","place":["Bangkok, Thailand"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pruettithada","family":"Hoonkaew","sequence":"additional","affiliation":[{"name":"HP Medical Center","place":["Bangkok, Thailand"]},{"name":"Department of Diagnostic Imaging, Mahachai Hospital","place":["Samut Sakhon, Thailand"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,9,29]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"17589","DOI":"10.1073\/pnas.0608757103","article-title":"Low micronutrient intake may accelerate the degenerative diseases of aging through allocation of scarce micronutrients by triage","volume":"103","author":"Ames","year":"2006","journal-title":"Proc.
