Anyone else curious or concerned about HRV scores in relation to others?
I've always been interested in HRV from a health perspective since it's a leading indicator of mortality and physiological readiness. Whilst I had a FR945, I used to track HRV every morning using the Elite HRV app combined with a chest strap. This enabled me to track my score, acute changes, system dominance (SNS vs PSNS) and trends. I can mostly do all this with the 955 now, albeit not with the same level of accuracy.
We often hear, or catch glimpses of others HRV scores. Many I see can be at the very high end of 60 to even 100+. These are exceptionally high, especially given Garmin measures in RMSSD as opposed to SDNN (which Apple use) which extrapolates higher numerical values.
This can't help but disappoint or concern those of us at the much lower-end of the scale. It does however help to understand that normative RMSSD scores have been indicated by researchers as: • 19 – 48 ms — healthy adults in the age group of 38 – 42 years, • 35 – 107 ms — elite athletes. It's worth noting that age is a key parameter affecting HRV, as well as genetics, health and lifestyle. See the following useful article link RMSSD, pNN50, SDNN and other HRV measurements | Welltory
- I'm a purely basic recreational male runner who is struggling (but trying!) to consistently achieve 20 miles p/w. I also fit into the 38 - 42 age group. A good nightly HRV average for me is around 38 and tends to be heavily subdued by deep sleep and snoring! I can achieve a good day time rested HRV snapshot of 60 which provides a little relief.
→ I'm curious to understand others HRV scores and experience, particularly in relation to volume and level of fitness. Are these high HRV values associated with more trained and elite athletes, have they always been high or have you seen an increase over time?
