Is the Best Predictor of Endurance Performance your Muscle?! | #13 ft. Dr. Robert Jacobs
Welcome to the Critical Oxygen Podcast! In this episode Dr. Robert Jacobs and I talk about the importance of skeletal muscle in predicting endurance performance. We focus on the significance of capillaries, myoglobin, and mitochondria in endurance performance, along with research comparing predictors of performance.
Here is a link to my master's publication discussing predictors of performance - https://physoc.onlinelibrary.wiley.com/doi/full/10.14814/phy2.14342
