#79 Roxanne Vogel On Cross-Adaptations Between Heat Stress & Hypoxia In Endurance Training

Join Scott Johnston for a chat with Roxanne Vogel. Roxanne is a doctoral candidate with a decade of R&D experience in the sports nutrition industry. Currently exploring interventions to improve physical and cognitive performance and adaptation to physiological challenges presented by extreme environments and prolonged exertion. An adventurer and high-altitude athlete who applied a novel pre-acclimation, training, and nutrition protocol to successfully summit Mt. Everest in 14 days door to door.
