WHOOP has updated its recovery algorithm with a major change for them which incorporates the RESPIRATORY RATE in their model that already includes HRV, rHR, and sleep performance.
Unsurprisingly to those who follow this area, WHOOP has found in its massive dataset, a clear link between PERFORMANCE and RESPIRATORY RATE. Indeed a 3 breaths/minute variation is all that it takes for WHOOP to trigger a change to your recovery to show.
There could also be CV19 link to respiratory changes too.
