It's amazing this still needs to be said, especially here
Here, sure. For the general public, these tools have been advertised this way. So if a good subset of HN still gets fooled, the layperson is screwed.
I dunno, if the Apple Watch said he had a vo2max of 30, that probably means he can’t run a mile in less than 12 minutes or so. He’s probably not at all healthy…
Health and fitness correlate but are different things. VO2max is more about fitness than about health.
Also, looking at https://en.wikipedia.org/wiki/VO2_max#Reference_values, 30 is about average for men in their 40s/50s, which, form a quick google, I estimate is the author’s age range.
Health metrics are absolutely tarnished by a lack of proper context. Unsurprisingly, it turns out that you can't reliably take a concept as broad as health and reduce it to a number. We see the same arguments over and over with body fat percentages, vo2 max estimates, BMI, lactate thresholds, resting heart rate, HRV, and more. These are all useful metrics, but it's important to consider them in the proper context tha…
Measuring metrics is easy, it's the algorithm on the backend that matters. There's a reason why Oura rings are expensive and it's not the hardware - you can get similar stuff for 50€ on Aliexpress. But none of them predicted my Covid infection days in advance. Oura did. A device like the Apple Watch that's on you 24/7 is good with TRENDS, not absolute measurements. It can tell you if your heart rate, blood oxygen or…
My general take on any AI/ML in medicine is that without a proper clinical validation, they are not worth to try. Also, AI Snake Oil is worth reading.
Imagine if as a dev someone came to you and told you everything that is wrong with your tech stack because they copy pasted some console errors into ChatGPT. There's a reason doctors need to spend almost a decade in training to parse this kind of info. If you do the above then please do it with respect for their profession.
... and you won't believe what happened next!
Can we do away with the clickbait from MSN? The article is about LLMs misdiagnosing cardiovascular status when given fitness tracker data

>I'd go so far to say this is probably the case for most people. Your average person is in really poor fitness-shape but just fine health-shape. Modern medicine has failed to move into the era of subtlety and small problems and many people suffer as a result. Fitness nerds and general non-scientists fill the gap poorly so we get a ton of guessing and anecdotal evidence and likely a whole lot of bad advice. Doctors wo…
As someone who is fit and active,in their 60s with zero obvious symptoms, but is nonetheless on cholesterol and blood pressure medication, this isn't true (in the UK, at least)

Of course, the real solution is to stop using Microsoft products, which I did.

Incidentally I got rid of mine recently. It is bliss not having one.
Also VO2 max is a crappy measure of fitness. I apparently had "average" VO2 max after a treadmill test. I can hike 50km with a 2km elevation gain in one go and not die. People with higher VO2 max I know, dropped out.
