In this episode of Fast Physiology on the Critical Oxygen Podcast, Dave Schell and I discuss the concepts of cardiac drift and physiological decoupling. We explore how heart rate responds to prolonged exercise, the physiological mechanisms behind these phenomena, and practical training strategies to mitigate the effects of cardiac drift. The conversation emphasizes the importance of hydration, heat tolerance, and consistent training for endurance athletes. TAKEAWAYS 1) Cardiac drift refers to the increase in heart rate at a steady power output over time. 2) Decoupling compares heart rate to power output, indicating fatigue resistance. 3) Hydration and cooling are crucial for maintaining performance during exercise. 4) Training in specific conditions can help athletes adapt to different environments.

Through readings, dialogues, and interviews with scholars and independent thinkers, the series examines how our inherited forms of mediation constrain the emergence of new collective possibilities.

Our purpose is to help make the critique of value publicly intelligible, opening a new horizon of understanding from which real social transformation can arise.
