![]() ![]() Most HRV apps and wearables use a measure called RMSSD, which is a simple measure of high-frequency HRV - the kind most related to parasympathetic nervous system activity. 2019) which is why it is such a great indicator of health.Īn important aspect to bear in mind when comparing HRV numbers from different apps or devices is that they depend on which HRV measure is being used and how it is taken. HRV measures the activity of the parasympathetic branch of the autonomic (unconscious) nervous system (ANS), which decreases during aging, and dysfunction of the ANS underlies cardiovascular and other age-related inflammatory diseases, such as type 2 diabetes ( Jandackova et al. HRV baseline numbers tell a story about your prospects for healthy longevity.Changes in the HRV baseline (a rolling average of daily measures) correlate with changes in athletic performance and may even predict future performance changes following a training block ( Buchheit et al., 2009 and Flatt & Esco, 2015).To answer the second point, the two key reasons you should care about your HRV number are: This is because average/normal levels of HRV vary by a factor of 10:1 or more depending on the group you are comparing to. Why does your HRV number matter anyways, and what is it that you’re trying to achieve by tracking HRV trends?įor the first point, in order to determine whether your HRV is good, normal or bad, you need to be compared to a group of people of the same sex, similar age and training status.What is your personal situation? How old are you, what sex are you, are you a competitive athlete, age group/weekend warrior, an active person or someone who has been sedentary and is trying to improve their health?. ![]() What you need to know about HRVīefore attempting to give any numbers that athletes and those interested in improving their fitness can use for comparison, we need to address two questions: Over the 10+ years I’ve been working with Heart Rate Variability (HRV), I’ve lost count of the number of times I’ve been asked whether an ithlete user’s HRV number is good, and if not, what does good look like. ![]()
