Interesting observation on the ketosis measurement method.
Still, probably the easiest way for such a simple study.
I share your feelings about study length.
Sure “adapted” after 3-4 weeks, but how adapted and is there longer term adaptation? I’d guess yes based off of personal experience.
Also, how relevant is such a study on a non athletic general population? Does training change or augment keto adaptation? Drawing a broad general conclusion on the usefulness of keto adaptation in athletics from test on couch potatoes seems…well…stretching it quite a bit to be kind.
I wrote the author from my .edu account asking for clarification on the data. I’d love to get a look at the spreadsheet.
-What were the measured differences by gender?
-Was there a difference in measured power when sorted by activity level?
-Was there … when sorted for both gender and activity level?
Still, I do love the simplicity. This sort of study could be easily repeated by a bunch of grad students at almost any university with a decent kinesiology department and a gym.
