Resting Heart Rate and Heart Rate Variability (HRV): What’s the Difference? — Part 3, Population-level data

Blog post by Marco Altini

In part 1 of this series, I covered the basic physiology of heart rhythm regulation. In part 2, I discussed the technology required for these measurements, why some sensors can be trusted, and why others can be used just for resting heart rate, and not for HRV.

In this blog, we finally start looking at the data, and in particular at population-level differences in resting heart rate and HRV, what factors consistently show changes in resting physiology, and what we can derive from this type of analysis.

We will discuss absolute values and differences between subgroups of the population with respect to:

• Sex
• Fitness level
• Ageing
• Body mass index
