I found an interesting Russ Roberts podcast with Art DeVany. The first 25 minutes is about baseball and steroids, and while I’m not a baseball nut, I still found DeVany’s ideas quite interesting.
The rest of it is about evolutionary diets and fitness. It’s definitely worth hearing, no matter which thing you’re interested in.
Re: cardio vs HIT, I never thought of this (paraphrased from memory and show notes):
For example, most of the early laboratory work on exercise was done with aerobics exercise because that was done in the lab. You can’t do anaerobic or intense exercise very well that way because the body never hits a steady state. Models are far more difficult. There’s bias toward testing aerobic exercise simply because that’s where the light is…
(i.e. Look for your keys under the street light because the light is better there.)
I have switched to sprints/HIT myself – it sure takes a lot less time! That’s not to say that I won’t do walking, hiking or yoga, but for the moment, I’m not taking them seriously as training exercise.
