Episode notes
HRV Defined
- Heart rate variability (HRV) measures beat-to-beat heart rate changes, reflecting autonomic nervous system activity.
- Higher HRV often suggests more parasympathetic activity, potentially indicating better recovery and performance.
HRV Measurement
- While an EKG is the gold standard, wearables offer convenient HRV tracking using photoplethysmography.
- However, wearables haven't been fully validated and may have accuracy and precision limitations compared to EKGs.
Interpreting HRV
- Don't compare HRV data from different measurement methods or devices.
- Higher HRV generally suggests greater parasympathetic activity, but consider individual factors like age, sex, and health.
