The Human Energetics and Thermoregulation (HEaT) Laboratory is dedicated to exploring the metabolic needs and changes that occur around exercise with special attention to nutritional manipulations and the impact of both internal and external thermoregulatory stressors. The goal of this lab is to better understand the impact of nutritional, hydration, and thermoregulatory interventions on performance and safety.
