HRV (Heart Rate Variability)

Definition

HRV is the variation in time between consecutive heartbeats. A higher HRV generally indicates better recovery, parasympathetic nervous system dominance, and readiness to train. Lower than normal HRV suggests fatigue or stress.

Why it matters

HRV is one of the most sensitive early warning indicators of overtraining, illness, and accumulated fatigue. Monitoring HRV trends helps athletes decide when to push and when to rest.

How FlipMP uses it

FlipMP syncs HRV data from Garmin, Polar, and Apple Watch. It tracks 7-day rolling average and flags deviations. The AI coach integrates HRV data into recovery recommendations.
