About This Episode
HRV4Training creator Dr. Marco Altini explains how HRV measures stress response and why it's more sensitive than heart rate alone. Covers how parasympathetic suppression during stress makes heartbeats more constant and elevates heart rate.
Key Takeaways
- HRV measures variation between heartbeats, not a constant rate
- Low HRV reflects high stress - heartbeats become more constant
- HRV is 5-10x more sensitive to stress than heart rate changes
- Mediterranean diet and avoiding ultra-processed foods improve HRV
- Stick to basics - move, eat well, exercise, manage stress
