#35 Everything You Need to Know About Athlete Sweat Testing and Hydration Performance
Mar 30, 2021
In this episode, I talk with sports dietitian Brooke Schohl about sweat testing and how it takes the guesswork out of sports hydration, determines your personal hydration needs and optimizes your performance.
After chatting with Sports Scientist Andy Blow in episode 34 about individual electrolyte loss rates and athletic performance, I scheduled an Advanced Athlete Sweat Test and determined I am a “heavy sweater” with high sodium loss rates. This information is a game changer!
