You spoke about the limitations of HRV in giving an accurate picture of “recovery” as it is only a single metric in a Q & A podcast episode (which I can’t for the life of me find now).
I do quite a bit of aerobic training (swimming and paddling as I intend to do some paddling races) (plus 3 resistance sessions of BBM templates) and have been wearing a WHOOP band for a year.
It is largely useless in that it doesn’t prompt me to modify my training behaviour in any way based on my recovery scores, as I go on how I feel (RPE) and don’t look at it prior to training.
My question is — given all the beat up about HRV being so informative, which I think is largely for marketing purposes — what other metrics affect our performance and recovery? I was trying to explain to a friend with a WHOOP why the information we gain is limited but I couldn’t elaborate on specifics.
As an aside, the one thing I like about and the reason I got it is it is WHOOP gives me reassurance re: how much sleep I get as I tend to underestimate this. I see how you say it could nocebo re: sleep but for me it seems the opposite. That said, I certainly don’t NEED a WHOOP and won’t be renewing my membership!
