Over the past few years we have put together a few guides and additional educational material that covers many aspects of HRV measurement and data interpretation
You can find them below
THE ULTIMATE GUIDE TO HEART RATE VARIABILITY
In this guide, we cover many aspects of HRV measurement, data interpretation as well as plenty of examples that you can look at to better understand how to make use of the data, and how HRV relates to training and lifestyle stressors
RESTING HEART RATE AND HEART RATE VARIABILITY, WHAT'S THE DIFFERENCE?
There are key differences between resting heart rate and HRV, which need to be understood to make good use of the data. In this series, we cover the physiological underpinnings, technological requirements, and show plenty of data at the population and individual level, which will help you master these aspects

The blogs below provide key insights on more nuanced aspects of HRV data collection. In particular, we explain why some devices can only provide noisy estimates, while others are able to provide a reliable assessment of resting physiology
