Wearable-assessed physiological responses identified a digital phenotype of allostatic load characterized by elevated cardiometabolic activity and blunted heart rate variation during sleep.
Observational
Is there an association between the allostatic load index and wearable-assessed physiological responses during strenuous military training?
Wearable devices can identify a digital phenotype of high allostatic load during military training, which may help guide training modifications to improve readiness.
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.
Feigel et al. (Wed,) conducted a observational in Allostatic load. Wearable physiological monitoring was evaluated on Association between allostatic load index and wearable physiological response. Wearable-assessed physiological responses identified a digital phenotype of allostatic load characterized by elevated cardiometabolic activity and blunted heart rate variation during sleep.
