Energy balance

Allostatic load (AL) represents the cumulative physiological stress and cost of adaptation, and can be measured using an Allostatic Load Index (ALindex) to guide nutrition and exercise interventions.

For elite athletes, consider monitoring allostatic load using biomarkers (like CRP, resting heart rate, HDL, waist-to-height ratio, and HbA1c) to assess cumulative stress. This can help adjust training and nutrition to prevent overtraining and injury.

ModerateQualifiesMEDIUM confidence
The allostatic load can increase dramatically if the system has superimposed on it additional chronic loads (inactivity or overactivity) that exceed the capacity to cope... Allostatic overload has been defined as 'long-term energy-dependent functional and/or structural dysregulation and breakdown that arise due to chronic allostatic load, leading to accelerated aging, disease onset and progression, and increased mortality risk'

Why this rating

It is a theoretical framework proposed by the authors, supported by citations but not a primary clinical trial result.
