Heat Training for increasing red blood cells?

I think it was Clayton Young and Conner Mantz that do sauna sessions while training (?). IMO it doesn't do much compared to altitude or other stimuli but I've never seriously tried it myself so I can't say.

I have a sauna in my hypobaric chamber which I keep a treadmill in so I do most of my training in there.

Why do athletes believe that they don't enough red blood cells?

doesn't increase red blood cells, increases blood volume

this ain't new

And how do you think your body knows when to create new red blood cells? I will give you a hint: it has to do with the concentration of red blood cells floating in your blood plasma. And guess what happens if you increase plasma volume? The proportion changes! And for the class, could you tell us what you think happens next, Johnny?

What happens when you increase blood volume is usually an increase in plasma volume, which allows you to go further at the same effort level.

Do you believe that "stress erythropoiesis" is better than "steady state erythropoiesis"

My FL summer training should pay off. Dew points of high 60s feel amazing, I’ve only run in those conditions two or three times in the past 4 months.

It does both. The theory is that after plasma volume increases, RBC increases as well to keep hematocrit consistent.

this is more than a little bit of a retardded theory

otherwise, wtf does hematocrit drop when we get in shape compared to being sedentary?!

i think sometimes people are actively trying to be ignorant on this board

when you run you generate much more heat and you learn to adapt to it.

on a bike you get only really hot when you climb.

so my bet would be that cyclist want similar adaptions to heat like runners.

that your blood gets thicker when you sweat a lot sounds kind of logical.

it doesn't.

5 weeks of 5 weekly heat training sessions increased hemoglobin mass and red blood cell volume.

It's like the old saying goes, heat is the poor man's altitude.

A lot of runners in warmer climates have no idea how much the heat adaption of their home climate augments their fitness in more ideal running conditions, because they usually race in the same climate they train in.

If runners in the southern US and Mexico went north for goal races during summer, they may be very surprised at how well they do.

Another underrated form of heat training is doing all your running on a gym treadmill. Most gyms are cheap with their A/C and keep the indoor temperature around 75-80°F (24-27°C), which is much warmer than ideal for running itself, plus the poor indoor air flow and stagnation further challenges your aerobic system. Race outside in cooler calm conditions and you might run far better than expected.

So what do you base your "opinion" on?

I was thinking about this the other day. I think training in heat makes you good at running in heat. I think training at altitude makes you good at running in cold. I believe this is why Colorado teams have done well in rainy conditions even though it doesn’t rain that much in Colorado. I think the thicker blood you get at altitude is a game changer in rainy low altitude races and it’s why CU upset Wisconsin way back when and why Colorado athletes dominated at NXN and Runninglane last year.

Are they actually focusing on this as a legal means or are they saying they are focusing on this (same goes for ketones, bicarb, etc.) while doing something else that is not legal?
