Does overtraining cause mitochondria to dysfunction? We look at data in the Flockhart study on excessive training and compare them to the headlines, a similar overtraining study using proteomics, and a published response to Flockhart. We break down mitochondrial function, what various measurement methods actually tell us, why your mitochondria are probably just fine, and why these studies raise more questions about mitochondria's role in overtraining (if any) than they answer. Finally, we answer your listener questions on the Flockhart study, mitochondrial function, and overtraining.

Watts Doc #41: Does Overtraining Actually Make Mitochondria Dysfunction?

After some background information on what redox state means for exercise and your mitochondria, we look at some experiments linking various intensities of exercise to adaptations. Then we look at where these signals overlap with dieting and rest, and tie these into advice and realistic expectations for training, recovery, and nutrition. We also answer your listener questions on RED-S, measuring recovery, exercise intensity, and more.

Watts Doc #47: The Redox Role In Adaptation, Recovery, and Nutrition

This episode goes deep into the integral role that PGC-1ɑ plays in turning exercise signals into aerobic adaptation and improved endurance performance. We then dig into the very surprising results of studies that selectively knock out the PGC-1ɑ gene. Finally, we discuss potential uses of this knowledge for training applications and interpreting the literature, the actual best ways to know if your training (or training "hack") is working, and answering your listener questions.

Watts Doc #48: How PGC-1ɑ Does and Doesn't Live Up To The Hype

We dig deep into a meta analysis' findings on the difference in muscular adaptations between training intensity and volume, especially what we can differentiate between continuous moderate intensity, HIIT, and sprint interval training. We also discuss the paper's findings on one aspect of "mitochondrial function", bullet point some practical takeaways, and answer your listener questions.
