Defintion for Heart Rate Variability (HRV)
Heart Rate Variability (HRV) is the physiological phenomenon of variation in the time interval between consecutive heartbeats, measured by the variation in the beat-to-beat interval.
Long Definition
Heart Rate Variability (HRV) measures the variation in time between heartbeats, reflecting autonomic nervous system balance. Higher HRV indicates better cardiovascular fitness and stress resilience. Runners use HRV to gauge recovery and readiness for training. For example, a consistently low HRV might suggest overtraining or insufficient recovery. Monitoring HRV helps runners optimize training loads and prevent injury. Apps and wearables like WHOOP or Garmin track HRV, providing actionable insights. Understanding HRV allows runners to tailor their training for improved performance and health.
kaizen Insights
HRV is a marker some runners use to monitor recovery. Trends over time are more useful than single readings.
