We talked about some of the strangest and coolest research topics in endurance sports for this episode! Basically, the science discussions went long, so we just ran with it. The main discussion was…

I love to say missing link because heat training has been this black box for a while.
So you see all of this information in real-world practice, and then you don't really see the studies backing it up.
And since that offset was identified a few years ago, we started to see the studies fill the gap and come back with the results we expect.
in a lot of these heat studies, we're seeing these drawn-out protocols, especially focusing on active heat, which can have more of an inflammation-based response.
And the question has been, like, okay, can we achieve similar findings with passive heat? And I feel like we're starting to fill that missing link.
And I like that science is doing it in a practical manner of ways in which, like, it feels very attainable for an athlete that doesn't have, you know, a bunch of extra hours a day to spare to do these protocols.
And this is also telling us stuff about how the body adapts, not just to heat, that we'll get to at the end, so it's very strange.
So this is the title: Daily hot water immersion preserves altitude-induced hemoglobin mass expansion following descent independent of EPO.
