Watts Doc #40: Endurance Adaptation Is Not Substrate Oxidation

Empirical Cycling Podcast · Watts Doc #40: Endurance Adaptation Is Not Substrate Oxidation

This episode breaks down the origins of endurance performance and how cells control substrate oxidation. We review a paper looking at the difference in adaptive aerobic signals when participants used significantly different amounts of fat and carbs at the same intensity. We then look at the role of mitochondria in cellular energetics, the pivotal role they play in aerobic endurance adaptations, and finally what the training implications are. Plus we answer your listener questions submitted to Kolie's Instagram.
