So this study was on adults aged 40-69, over 8 years or so. And then they had 500k possible people, of which 200k or so had accelerometer data, and then 17k or so of those actually had done a vo2max test, which they admit might select for a slightly healthier population. I don't know if you can say much if anything close to the headline from looking at this data.

I guess the one interesting thing is that they only had accelerometer data, so i guess maybe this wouldnt undercount activity minutes the way my garmin does (i can do a lot before i cross 100bpm or whatever the threshold is).

It seems like a lot here depends on how you try to measure this activity. Garmin uses the hr mostly i think so basically most of my stepcount is ignored. Pure accelerometer data underrepresents resistance training and overrepresents relatively low energy fidgeting.

I feel like this is a garbage study tbh. Or a mid study with a garbage headline slapped on it.
