Heart Rate Variability (HRV) has become a popular marker of health and can be measured by many different wearable devices. Sports, wellness, and performance coaches and exercise professionals should understand the basics of this fascinating phenomenon. Learn how HRV indicates internal stress and how the information can be used to improve health, performance, and recovery.
  • Details
HRV is regulated by the autonomic nervous system (ANS), and its sympathetic and parasympathetic branches, and it is commonly accepted as a non-invasive marker of autonomic nervous system activity. The sympathetic branch of the ANS is the stress or fight or flight system, getting us ready to act, react, and perform. Conversely, the parasympathetic branch slows the heart rate and increases HRV to restore homeostasis after the stress passes. This natural interplay between the two systems allows the heart to quickly respond to different situations and needs.
