how come the ones who live the longest never do the HIIT treadmill hamster wheel training, but rather frequent light-to-moderate walks, bicycle rides, garden work or the like?
- manmal 2mo agoCan you really do HIIT on a treadmill? It doesn't sound safe to sprint on a machine. Re your observations. Are you referring to elderly people? I'm not sure this study is about them. My mental model of this mechanism is that relatively young people can choose between e.g. long distance running and sprinting, and that the latter will yield better cardiac outcomes.
- jjcob 2mo agoIn my experience HIIT works very well on a treadmill. Many treadmills even have presets for HIIT.
- manmal 2mo agoThe kind of HIIT I'm doing is only 10-20s bursts, to stay within ATP-PCr energy metabolism (little lactic acid production). A short sprint followed by 2 minutes rest. That's hard to achieve with a treadmill. https://en.wikipedia.org/wiki/Bioenergetic_systems#ATP%E2%80%93CP:_the_phosphagen_system https://en.wikipedia.org/wiki/Bioenergetic_systems#ATP%E2%80...
- jjcob 2mo agoYeah, it doesn't actually work for "real" sprinting. Standard treadmills take too long to get up to speed. But if you do 30-60s work intervals treadmills work just fine.
- readthenotes1 2mo agoI guess it depends on your age and current fitness level. When I was young and fit, I could outrun the treadmill for the periods of time I needed. The treadmill also wasn't able to change speeds fast enough to really do the good Sprint simulations
