Effects of 24-h sleep deprivation on circulating irisin, BDNF, and soluble klotho responses during exercise in the heat in young and older males.
Sleep deprivation and heat stress commonly coexist in occupational, athletic, and environmental settings and may disproportionately increase physiological strain in older adults. We examined whether 24-h sleep deprivation alters circulating biomarkers linked to proposed roles in metabolic adaptation (irisin), neurophys...
