Had no idea heat acclimation was something so important and potentially life threatening... Breaks my heart watching this video now after what happened to Lazar 😢 #RipLazarÐukić
Tia will not only win, but dominate. Shes the GOAT. Ricky Gerard on mens side but less certain. As usual, great content. I was wondering if sauna in the summer was still beneficial. Maybe so.
Regarding the mentioned study: I wonder why the groups trained at different % of VO2max (50% in the 40°C group and 45% in the 13°C group) when temperature was supposed to be the variable of interest?
Great point. Likely because the authors set a fixed wattage. Because of the difference in termperatures, this corresponed to a lower percentage of their VO2 at 13 degr C.
@@wod-science That sounds reasonible, but I would argue, that the internal factors - such as at what % of VO2max the body has to operate, i.e. the applied stressor - are likely more important to initiate an adaptation or the kind of adaptation than an external factor like a fixed power that has to be achieved. For VO2max for example it is often stated that time spent above 90% of VO2max is one of the most potent predictors, regardless at what wattage this is achieved, right? Due to the stronger stressor (% VO2max during training) I woul therefore expect a stronger adaptation signal in the high temperature group.
I’d assume so with my 0 knowledge on the subject. A shirt is like a cotton wetsuit and will hold some sweat to the body. Some will evaporate off. But I’d assume this means there is a temperature gradient where the outside of the shirt is the coldest from evaporation and convection and the inside of the shirt is warmer closer to the skin temp. I’d also assume this depends on working out inside vs outside in the direct sun. I’ve been doing runs in 100 degrees f to get heat acclimated. It feels great with the shirt off if there are clouds. I feel cooler and lower heart rate. If the sun comes out then the radiation heat directly on the skin feels way hotter without a shirt. I feel like radiation transfers heat better than convection so wearing a breathable shirt would reduce external heat but reduce efficiency of evaporation and convection. All that said, shirts off in the gym. There is an answer from an unqualified person who could be 1000% wrong. Hope that helps haha
Convection, yes. Evaporation maybe not. If sweat drips off it didn’t get to do its job. And in direct sunlight a thin, light ly colored material can minimize heat directly radiated into your skin.
It is a great question where I do not know the answer to. The simple solution would be to do a study. Same workout, same warm conditions: group A with cotton shirt, group B with light, sweat absorbing shirt and group C shirt less. See who's core temp rises the quickest.
I'm rooting for Laura as well!
As for the fellas, I'm rooting for Ricky!
They say heat is the poor man's altitude...
Excellent. Thank you.

It is… RIP Lazar. It’s all so sad. 😔

The program did a video on the heat last week 😃👌🏻
Soooo… Do i get better convection by taking my shirt off? 😅 just asking for every crossfitter ever 😁

@@wod-science Yeah good luck finding enough CrossFitters willing to do an entire workout with a shirt on 😛.
I sweat very fast and a lot. Does this mean I‘m already quite heat acclimated?
Yes, likely. This is a good sign. You live in warm conditions?
