Even thought I always double in the heat and try to run in the shade in the AM at dawn and run again just when the sun goes down, keeping runs short to not dehydrate to much...
Not sure why, but it works, Benji Durden used heat training
there are multiple advantages to moving/training at altitude (for responders): 1. increase in rbcs 2. increase in blood volume 3. increase in lactate buffering capacity 4. increase in anaerobic capacity (not often talked about, don't get hung up on this plz) 5. there are others, but those are the big 4 if memory serves me right
advantage to training in humid conditions: 1. increase in blood volume 2. there are others, but that's the main one (lot of people about heat shock protein for instance, but i honestly forget it's impact rn)
an increase in blood volume, even without any increase in rbcs (thus hematocrit goes down even if global hemoglobin levels are effectively static) increases aerobic capacity
if you do all your training mid-day in a hot/humid environment of course your results are likely to be bad. that would be like living at 6500' but choosing to drive further up the mountain to do all speed workouts. hard workouts generally need to be early morning or later in the evening, while the more moderate/easy workouts can be performed with more sun exposure
A few things:
1. Increase in RBCs at altitude is temporary, the RBC count goes back to normal when you return to low altitude.
2. Blood volume goes down soon afteryou arrive at altitude due to lower humidity and takes 2 to 3 weeks to increase to normal levels.
3. Lactate isn't buffered. It's not an acid. H+ is buffered partly bt Lactate production.
4. "Increase in anaerobic capacity" really? Go on then, explain that, I challenge ya.
Then explain how an increase in blood volume with a cocommitant decrese in hemoconcentration increases aerobic capacity? You will really have to work hard on that one, but don't give up.
I think the entire world understands attitude works. Japan has a lot of runners that train in humidity that do well, Uganda has both which must be brutal.
5000: 12:35 10000: 26:11
checks out
No it doesn't Uganda is pleasant year round with Dew Pounds in the 50s -60s. Why bother posting?
Humidity kinda ruins running for me during the summer, way way more difficult than the dry altitude I’ve experienced in CO. I also seem to be relatively bad in humidity compared to most by doing worse in summer races then crushing them when the temps drop back down. Like it blows my mind how many people are able to just do long runs at basically the same pace as winter training, meanwhile I turn into slug plodder.
