Heart Rate Variability Basics

Interpret HRV cautiously

Heart rate variability measures time differences between beats; higher generally indicates better recovery. Track trends at similar times, note stress/sleep/training impacts, and avoid overreacting to single readings.

Measure Consistently

Track at the same time/conditions for trends.

Context

Sleep, stress, illness, and training load affect HRV.

Use Wisely

Adjust training/rest based on trends, not one-off dips.
