What is an athlete field evaluation?

In an athlete field evauation, one or more athletes are evaluated during training, practice, or competition for hydration status (pre- and post-session), fluid intake, and sweat fluid and electrolyte (sodium, potassium, and chloride) losses. Individual-specific hydration and dietary strategies are provided to help each athlete more optimally prepare for, manage, and recover from fluid and electrolyte losses incurred during training and competition. Thermal strain (core body temperature, heart rate, and physiological strain index) can also be monitored.
