The Effect of Glycerol and Sodium-Induced Hyperhydration on Half-Marathon Time-Trial Performance in Trained Runners in Hot Conditions

Introduction: Exercise performance is impaired in hot conditions ( ≥25°C) with the deleterious effects of exercise-induced dehydration (i.e., a reduction in body mass ≥2%) potentially contributing to this outcome. To reduce the net fluid loss incurred during exercise in the heat, athletes may deliberately undertake pre-exercise hyperhydration strategies that i ncrease their total body water and prevent or delay exercise-induced dehydration. Hyperhydration is achieved by ingesting large volumes of fluid with sodium and/or glycerol osmolytes.
