Kyle Helson

Kyle Helson, a NASA scientist and national champion sprinter, joins to explore a fascinating study on muscle glycogen recovery and its surprising impact on high-intensity interval performance. They discuss how delayed carbohydrate feeding can reduce performance, even with equal total calories. Helson explains the complexities of glycogen storage and its significance in sports. They also dive into practical coaching takeaways about post-exercise fueling and discuss how these findings could impact training strategies for cyclists.

In this engaging discussion, Kyle Helson, a NASA scientist and national champion sprinter, explores the concept of durability in endurance training. He delves into the history and definitions of fatigue, questioning traditional metrics like kilojoules and their implications on performance. Kyle critiques recent literature on durability, emphasizing the importance of standardized protocols and the interplay between power and endurance. Listeners gain practical advice on improving their durability, alongside insights into the nuances of training adaptations.

Kyle Helson, a NASA scientist and national champion sprinter, brings expertise in experimental design and physiology. He discusses how to set up n=1 training tests, control confounders like timing and travel, and use repeated testing to separate noise from real change. Practical rules for dose standardization, tracking perceived effort, and clever within-person replications round out the conversation.
