The Cardiovascular System and Athletic Performance
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.
Reducing cardiovascular drift and increasing fiber recruitment are key components of sustainability.
