What Is HRV?

About this video

A brief explainer in which Brecka defines heart rate variability as the variation in time between heartbeats, distinct from heart rate itself. He states higher HRV indicates a well-functioning, adaptable autonomic nervous system while lower HRV can signal stress or fatigue, and presents monitoring HRV as a route to better stress resilience and physical performance before the clip turns to actionable steps.

Key takeaways

• Brecka defines HRV as beat-to-beat interval variation rather than beats per minute
• Brecka claims higher HRV reflects, in his telling, a more adaptable autonomic nervous system
• Brecka presents HRV as an indicator of stress, recovery and overall health
