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.
