Heart Rate Variability (HRV) vs. Heart Rate
As you may know, HRV and heart rate are calculated differently and should be analyzed differently. We wrote a blog post that discusses the uses of both: HRV vs. Heart Rate
Another question we get often is how HRV and heart rate can be used to detect overtraining syndrome. Heart rate can actually increase OR decrease as a response to overtraining. It depends on the type of training and the individual. Often high volume endurance training can lead to a decreased resting heart rate in overtraining. The research of Paul Laursen and Dan Plews mentions this, amongst others. This is another reason that HRV can be helpful when heart rate does not always paint the full picture.
We recommend tracking all changes occurring by utilizing the tagging and journal feature in the app to help track these symptoms.
