During sport and physical activities, maximizing performance  and safety is a vital component for athletes. I have been approaching this through understanding thermoregulatory mechanisms, optimizing hydration strategies, and sports science through the use of technology. These three factors are related to each other in dynamic and complex ways and have an impact on athlete performance and health. Training and competing in the heat have negative implications for performance and safety, including a higher internal body temperature, increased heart rate, changes in perceptual measures, and poor performance outcomes. These strains are exacerbated by dehydration even though dehydration independently decreases exercise performance. However, a lot of factors influence athlete performance and safety in addition to hydration and thermoregulation. Athlete monitoring allows practitioners to collect comprehensive information and examine athlete training status, recovery and wellness.
