Season 3, Episode 14 Dr. Bubbs interviews endurance expert Dr. Sam Impey, PhD to dive into periodized nutrition for elite and recreational endurance athletes. In this episode, Sam reviews the history of endurance nutrition, defines ‘carbohydrate availability’ and ‘train low’, and outlines how fasted training, two-a-day sessions and sleep low-train low strategies impact training adaptations. Sam also summarizes the glycogen threshold hypothesis under-pinning these strategies, talks train-low in team sports, and shares his view on the evolution of research in this area.
