The cardiovascular system powers endurance performance. Explore how training reshapes the heart, what causes cardiovascular drift, and why too much exercise may carry long-term risks.
Cardiovascular drift is an instability in heart rate and stroke volume over time. We show you how to determine it.
Cardiovascular drift is measured on the bike by looking at a rise in heart rate relative to power. Dr. Ed Coyle shows us the science behind it.
Reducing cardiovascular drift and increasing fiber recruitment are key components of sustainability.
We answer listener questions on training for long endurance events, cardiac drift, the types of inflammation, and much more.
