  • What does Andy Galpin says about HRV and Cardio Recovery?

  • Sources:

    provides detailed insights into heart rate variability (HRV) and cardiovascular recovery across various discussions.

    • HRV as a Biomarker: Galpin explains that HRV measures the variation in time between heartbeats and is a strong indicator of one's sympathetic and parasympathetic balance. A high HRV indicates a more relaxed and recovered state, while a low HRV suggests stress and a less recovered autonomic nervous system. He cautions against relying heavily on HRV scores from different devices, as they may measure HRV differently and may not be directly comparable 1 2.

    • Cardio Recovery: Galpin emphasizes the importance of heart rate recovery as a fitness metric. For example, a well-conditioned person should be able to bring their heart rate down to 80% of the max (e.g., from 200 to 160 beats per minute) within two minutes post-exercise. Faster recovery rates indicate better cardiovascular fitness 3.

    • Measuring Recovery: For those tracking recovery, Galpin recommends using a combination of subjective and objective measures, such as mood and HRV or resting heart rate. This approach helps in gaining a comprehensive view of recovery status without becoming overwhelmed by data 4.

    These points all highlight the nuanced relationship between HRV, cardiovascular fitness, and recovery, emphasizing the importance of thoughtful and varied measurement strategies.
