Energy Metabolism Models

NoteChapter Abstract

This chapter develops mathematical models of the energy metabolism dysfunction that lies at the heart of ME/CFS. It models ATP production, mitochondrial dysfunction, and the dynamics of healthy exercise response, then turns to the central clinical phenomenon of post-exertional malaise. The models are used to simulate the response to metabolic interventions, to analyse lactate kinetics and metabolic flexibility, and to describe mitochondrial dynamics and quality control. A consolidated cascade example ties the sections together, and a dedicated application guide explains how to use the models in practice. The chapter also extends the framework to connective-tissue and metabolic coupling.

NoteChapter Roadmap: How to Use This Chapter

For patients: read the Post-Exertional Malaise Modeling section to understand why exertion triggers post-exertional malaise in terms of energy reserves; it supports pacing reasoning.

For caregivers: read the Post-Exertional Malaise Modeling section for an intuition of the exertion–recovery balance that guides daily activity support.

For clinicians: read the Post-Exertional Malaise Modeling, Response to Metabolic Interventions, and Model Application Guide sections to apply metabolic reasoning and interpret intervention responses.

For researchers: read the full derivation from the ATP Production Models and Mitochondrial Dysfunction Models sections through the Mitochondrial Dynamics and Quality Control and Consolidated Cascade Example sections.

fig-energy-metabolism-model This chapter translates the qualitative understanding of energy metabolism dysfunction in ME/CFS (Energy Metabolism and Mitochondrial Function) into formal mathematical models. The models progress from individual metabolic pathways to an integrated energy production system, culminating in a quantitative framework for post-exertional malaise. All models use ordinary differential equations with Michaelis–Menten or Hill-type kinetics (Modeling Approaches); full parameter tables and derivations are in Appendix Mathematical Model Details.
