no hang on there, you said any hiit was better at vo2max improvement than any longer steady cardio / running.If you can run at max heart rate for 30 minutes straight, then interval training is not going to help you. Show me someone who can run at max heart rate for that long, and I'll say he/she is the best runner of all time.
You're getting hung up on the 20 seconds thing. It was a STARTING POINT, as I clearly said. How about running at max heart rate for 60 sec, and at fat burn rate for 2 minutes, alternating for 30 minutes? Would that make you reconsider? Will that get the 20 sec hang up you have out of your head? Where did I say running at a high rate for 20 sec is better than at a high rate for 10 minutes? Interval training is better than running at a high rate for 10 minutes because you can go longer and spend more OVERALL time in a max heart rate zone if you're alternating high and low heart rates. Again, exercise physiology expert, I said 20 sec was a STARTING POINT. ADJUST THE TIME SO IT FITS YOU. How else can I make that clear.
There's so many studies done on interval training it's not even funny.
Here's a few professional journal links. Search interval training all you want...

Here's a general information article written by the American College of Sports Medicine. They're a quite credible source...
The Basics of High-Intensity Interval Training
And I'm done. I almost forgot that you know everything and no one can tell you otherwise. Reading something and memorizing it isn't true intelligence. Actually understanding it and being able to apply it is.
that was an absolute statement on your part. Now it seem you are not at all sure if that's true and are rattling on about heart rate.
was your statement true ,or not
