The title is not really honest, it’s a 10 min “commitment”. If you frame it correctly, the result isn’t that surprising

The concept is still worth knowing. Intersperse sprinting into your jogging is extremely important. Or other similar intensity lifts.

  Fast sprints, fartlek [Swedish], in jogging was a thing 20+ years ago (Wikipedia says it was developed in 1930s). I got a knee injury and haven't jogged since, is it still a thing? Is this HIT a refinement of that?

Sure, but the high intensity is 1 minute total. 2 min warm up 20 sec sprint 2 min maintain 20 sec sprint 2 min maintain 20 sec sprint 3 min cooldown

  There is no control of not doing the 20 sec sprints, so i'm not sure how I can conclude that the sprints give the benefit vs the low intensity work surrounding it.

    Control would not be safe, going from 500w to idle can cause cardiac problems. Especially with elevated bmi.

      Control would be doing 10 minutes of low intensity.

    Empirically, it’s obviously necessary.

I disagree. The time durations differ by factor 5, more so it’s 1 min 500w + 9 min 50w compared to 45 minutes 110 w. To frame that: Physical Labour can be sustained for longer durations at about 75w, and you cannot safely jump from 500w to resting state without a cooldown. So imho the paper delivers what it promises.

I'd like to understand where this title came from. The title within the article, while longer, seems much more reasonable a statement: "Twelve Weeks of Sprint Interval Training Improves Indices of Cardiometabolic Health Similar to Traditional Endurance Training despite a Five-Fold Lower Exercise Volume and Time Commitment"

Time commitment is not really the limiting factor as to why people are out of shape anyway. HIIT is not a cheat code. Yes, technically it is just 1 minute of active exercise but oh boy will that minute feel like ages, especially if you are out of shape. It should intuitively make sense that that low intensity over a longer time and higher intensity over a shorter time would equal to roughly the same results (no exactly, they train slightly different things but let's keep it simple.) Whether you do HIIT or low intensity exercises, at the end of the day you still have to put in the work. There is no shortcut. People that are completely out of shape can do basically anything and it will give them great results. The hard part is building a habit of exercise.
