Allostatic load and perturbation resistance potential are core components of the allostasis framework [1], where the latter is defined as the difference between available resources and the energetic costs of allostatic load {fact:5, fact:6, fact:7}. Their inverse relationship is central to the model, as an increase in allostatic load typically results in a decrease in perturbation resistance potential {fact:2, fact:3, fact:4}.

formulaPerturbation resistance potential (PRP) is calculated as Eg – (Ee + Ei), representing the difference between allostatic load and resource availability.
claimAs allostatic overload (Eo) progresses, the overall allostatic load increases and the perturbation resistance potential (PRP) decreases.
claimAllostatic load indicates energetic requirements and is a reliable cue when resources are limited (allostatic load is close to Ecr, and Perturbation Resistance Potential is low), but it increases error when resources vastly exceed requirements (allostatic load is much less than Ecr, and Perturbation Resistance Potential is high).
formulaPerturbation resistance potential (PRP) is a quantity in the framework of allostasis that describes the difference between allostatic load and resource availability, calculated as Eg – (Ee + Ei), and reflects an individual's vulnerability to allostatic overload Type 1.
claimStrategy 1 for endocrine response involves glucocorticoids gradually elevating in direct inverse correlation with the difference between allostatic load and resource availability (PRP) when PRP is low, reaching the ELHS activation threshold only when PRP equals zero.
formulaIn the model of allostatic load, perturbation resistance potential (PRP) is quantified as the difference between available resources and all energetic costs of allostatic load, including daily routines, life history stages (such as breeding, migration, and molt), and the impact of environmental perturbations.
claimThe article 'Allostasis revisited: A perception, variation, and risk framework' identifies allostasis, allostatic load, perturbation resistance potential, glucocorticoid, and environment as key concepts.
