Heat stress impairs exogenous carbohydrate oxidation during prolonged running when maintaining euhydration
Year: 2025
Type: article
Abstract: This study showed that exogenous carbohydrate oxidation is reduced by ∼20% during running in the heat, even while controlling fluid intake to maintain euhydration, highlighting that heat stress alone impairs exogenous carbohydrate use. These findings suggest a lower exogenous carbohydrate oxidation and a greater reliance on endogenous stores when exercising in the heat, independently of the effects of dehydration.
