Identifying a digital phenotype of allostatic load: association between allostatic load index score and wearable physiological response during military training

Year: 2025

Type: article

Abstract: This investigation for the first time observed an association between the traditional measurement of allostatic load, the allostatic load index, and wearable-assessed physiological responses to strenuous military training stress. We found a novel digital phenotype of allostatic load characterized by chronically elevated and variable cardiometabolic activity with blunted variation in heart rate during sleep. This phenotype may serve as an at-risk profile of high allostatic load and prompt in-training modifications to enhance posttraining readiness.
