How HRV Predicts Autonomic Nervous System Recovery
Heart Rate Variability (HRV) is the variance in time between consecutive heartbeats, measured in milliseconds. It serves as a biomarker for cardiovascular fitness and recovery.
How HRV Predicts Recovery
- High HRV: Indicates a balanced, responsive autonomic nervous system with strong parasympathetic (rest-and-digest) activity.
- Low HRV: Indicates your body is under stress, with dominant sympathetic (fight-or-flight) activity.
Practical use: Check your baseline HRV trends to help customize your training intensity and identify when your body needs active rest.
