ABSTRACT
Training and competing in the heat has negative implications for performance and safety in soccer. It is important for players, coaches, sports scientists, and sport medicine professionals to utilize hydration and heat strategies to optimal performance and reduce the risk of exertional heat illness. Assessing hydration in the morning based on a combination of thirst, urine concentration, and body weight is an effective way to ensure proper hydration. To prevent exertional heat illness during soccer, it is critical to understand proper definition, etiology, recognition, and treatment of exertional heat illnesses. Heat acclimation and cooling are two effective methods to improve performance and decrease the risk of exertional heat illness during soccer.
