Here are two related stories based on Whoop, knowing my readership I’m hoping that at least one of them will be of interest to most people.
Whoop & Broadcasting HR
The first two versions of Whoop couldn’t broadcast HR using any standard method. That’s changed with the v3 released earlier this year as Whoop 3 now broadcasts over BLE. Yay. As if proof were needed, here you go…
That’s my second 945 in the image, above. The first was the subject of ‘Buttongate’. I thought I was OK at first and was delighted that I didn’t suffer from the rather prevalent button pressing issue that everyone else seemed to be having. But eventually mine gave up too 🙁 and here’s the replacement. Unfortunately, I reckon that even with this new one (it’s reconditioned) every button presses subtly differently to the other 4…but at least they ‘press’.
Whoop hasn’t got any buttons to press, which is probably a good thing.
So, you can now pair Whoop to some gym machines and to many Android/iOS apps; or, of course, to any GPS watch or bike computer that supports BLE.
This somewhat opens up Whoop Review to ‘be tested’. When I did my original review, Whoop was very kind and provided me with my HR stats from their own backend system. I’m reasonably sure that no other reviewers had that data at the time. Well, now we all do!
Of course, Whoop know that wrist-based HRMs are subject to the vagaries of motion artefacts during exercise and consequently they also sell an “Impact Series Upper Arm Sleeve” and an “Impact Series Full Arm Sleeve” to encourage you to wear it elsewhere at key times. I’m not so sure how many Whoop users use those arm sleeves (where I would expect GREAT results). So let’s see what happens with the wrist readings.
I’m planning to do some tests on Whoop’s HR accuracy. I should be able to get MANY more data points than before. Let’s hope it’s good.
BEDTIME READING Whoop Review
Whoop & Alcohol
NO, it’s not a new kind of drink 😉
Next up is a piece of research by Whoop about the effects of alcohol and the time taken to recover from it. It’s an old piece but it’s doing the rounds again.
We all intuitively know that alcohol is not great for athletic performance mainly because everyone else says so. Perhaps only a few of us have tried to quantify that? I’ve not looked in any detail at the effects of alcohol on me as I don’t drink that much. However, I have noticed very poor overnight HRV readings after drinking but my subsequent night’s sleep always ‘seemed’ OK. And I left it at that.
Whoop did some research with their users who logged alcohol ‘events’ alongside sleep and workouts (as usual). In a nutshell, the finding was that alcohol affects us all differently but that effect can last for up to 5 days in some people. Here’s a bit more detail:
- 1-day post alcohol consumption, 74% of athletes showed reduced recovery metrics
- 2 days post alcohol consumption, 29% of athletes still showed reduced recovery metrics
- 3 days post alcohol consumption, 19% of athletes still showed reduced recovery metrics
- 4 and 5 days post alcohol consumption, 7% of athletes still showed reduced recovery metrics
Whoop’s 2015 study also found that, from a population of 148 athletes, 16.2% had higher rHR and 22.7% had lower HRV due to the after effects of alcohol.
