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.
Carbohydrate improves exercise capacity but does not affect subcellular lipid droplet morphology, AMPK and p53 signalling in human skeletal muscle
Regulation of skeletal muscle mitochondrial fatty acid metabolism in lean and obese individuals
Metabolic adaptations to short-term training are expressed early in submaximal exercise
Biochemical adaptations in muscle
Are you a CTL junkie? Terrified of letting it drop? Listen in. This episode takes a critical but realistic look at TSS and the metrics it's built on like CTL, ATL, and TSB. We discuss normalized power, what kind of fitness CTL can actually reflect, and answer listener questions.
