Research and Science
VO2max only tells you what would theoretically be possible, not what your body actually uses of it. And when it comes to pinning down your second lactate threshold, not even the 72 recognised models can agree.
A test shows you WHAT a body can do. A diagnostic shows you HOW it does it. Why that difference decides whether your Zone 2 is actually a Zone 2.
A watch does not measure your VO2max, it estimates it. Why that estimate is surprisingly good for recreational athletes, and why it misses for the very best.
Whoop says rest day, Garmin recommends threshold training. Why wearables contradict each other, and why picking your measurement method matters more than asking who is right.
What HRV really measures, why your nervous system sets the tempo, and why twenty seconds before you hit start decide the data quality of an entire session.
On many Garmin watches HRV recording is off by default and gets reset by firmware updates. Here is how to enable it so obseed can analyse your heart rate variability.
Sports are healthy? If you do them "right", absolutely. But... what does that actually mean? We look at the topic of "sports and health" from the angle we know best: data.
There are many sports platforms and apps these days. If a new demand arises, it usually doesn't take long for a corresponding offer to appear.
Books can be filled with knowledge about the human body. Entire libraries with the lack of knowledge about it.
