@@TrainerRoad Great! I hope it will be a podcast with him as a guest with a productive back and forth discussion and not just an explanation of your point of view.
I’m glad I found this podcast. I wake up at 3:30am to ride my bike on rollers in a closed garage. Thermometer reads 81 degrees. I enjoy it, when I ride outside air taste like candy:-) Hopefully Im getting faster and not hurting myself.
Fantastic podcast guys! This kind of content is pure gold, even for a newbie like me. Thanks TR and Dr. Minson for making this content available to the community.
Nate, Chad & Dr Minson, excellent science communication. Thanks you and I am really look forward to this podcast series in future. Keep up the great work at TrainerRoad.
I've done competitive cycling in South Texas and now Miami, similar summer temperatures and humidity but the biggest difference that affects me is the lack of wind compared to S. Texas. Huge limiter not having some wind help "move" the sweat off you body. I pretty much have to take summers off in Miami.
So glad to finally have an episode! I was really looking forward to the Science of Getting Faster podcast when it was first mentioned, and then it seemed to disappear for a while. I was starting to think you had forgotten about it!
Question! While heat acclimating, should I be taking in extra electrolytes in the time leading up to my event? Or just to what me needs are in my remaining training sessions? Sorry if I missed it in the vid- Great content-
If sweat doesn’t evaporate but rather drips off, it still seems like heat is leaving the body anytime warm sweat drips away. Are you saying it’s essentially the same heat that would leave the body through heat dissipating through the air, if sweat wasn’t present? If that’s the case then I see why you say sweat that drips off your body or gets wiped away w a towel doesn’t remove any heat (maybe more accurate?: it doesn’t remove any additional heat). In high humidity, is it best to wipe away sweat or leave it to maximize the amount that will evaporate? Thank you - great practical info here
Really interesting podcast, looking forward to the next episodes. Just had some questions: I've heard some people say that you should do heat acclimation training sessions without hydrating or at least minimally in order to (and I quote these people) "stimulate the cardiac output by working with a thicker blood due to dehydration". What are your thoughts on that? Also, do you believe that heat acclimation is less effective on elite athletes because their cardiac output is already close to their genetic potential? It has been shown that stroke volume plateaus in highly trained endurance athletes but not on less trained athletes. Thanks !
This is an interesting question and another for debate. I will say that the mechanism you mention is not the mechanism at play though! I will say that in general, most of the benefits come through the heat and not dehydration.
@@christopherminson2376 Thanks for taking the time to answer, I really appreciate it. It's great that there are researchers like you who take the time to explain to simpler people like us the physiology of cycling. Hope there will be a follow up, because I'd love you to further develop this argument. I would have thought that the increase in stroke volume was exclusively due to changes in blood composition: either the blood gains plasma volume because it's beneficial for heat dissipation, meaning the heart has to pump more blood and therefore develops cardiac output, or either the blood gets thicker because of dehydration meaning the heart has to "pump harder". Or is it a combination of both ? Or none..? Anyway, hope you'll keep on doing these, really love them. Thanks again !
Interesting new podcast series, looking forward to future episodes although personally the topic chosen for this first episode is a little esoteric and not really of much direct interest personally.
I'm sure there will be episodes you find interesting! I will say that I disagree with this topic being esoteric, as athletes at all levels (and in many different sports) are trying to understand the positive and negative impacts of heat on performance and training. If Tokyo 2020 (now 2021) ends up being as hot as feared, it could really impact who performs best at the outdoor events.
@@christopherminson2376 my point is more that in terms of “hierarchy of training needs” for the amateur athlete this is both well into rarified marginal gains and also non-trivial to implement. Just seems an odd choice for a first episode, but I appreciate the content nevertheless 👍
Great work. Perhaps if he matched hr for the heat group and the cool group, rather than 65% of ftp, then the results would be quite similar between the heat group and the control(cool). This study tells me that heart rate is an indicator of the body's perceived level of exertion. And we see this guy didn't really mess with the high intensity stuff, hot or cool group, those were always done cool, but what happens if he starts making that the variable that he tests for: intense intervals in heat vs intense intervals in cool, that would lead to some interesting findings I think.
Good thoughts! I can tell you that doing high intensity workouts in the very hot conditions, if done regularly, would be a detriment to performance over doing those in the cool conditions. The reason being is that one simply cannot do as much work (training stimulus to the muscles and neuromuscular connections) when they are fatigued in the heat. With respect to matching HR during heat/cool training, there are studies showing that matching HR results in a similar training adaptation. This is an important tool when the goal is to minimize the total work done by the legs.
Great podcast !! One question though: were the VO2max measurements made for both group-tests under identical conditions (temp. and humidity), or were the « cool « and « warm » groups had their VO2max measured at each their own specific training conditions?
So I am developing my "pain cave" and was wondering about the lasko fan you guys like. Is it reasonably quiet, or just move a lot of air at the cost of high sound levels....which model?
podcast made for me. I am sweat a lot during riding on trainer.. my towel gains kilos because of sweat If I use fan it's to cold for me.. how can i solve this problem? I am not using tops during indoor rides
Finding the balance of air circulation is tricky for sure. Try moving your fan around or getting creative with ventilation so that it's not so 'cold'. Good luck!
I can tell you from experience there are limits to this. Even 15 minutes of streenuous cycling in 112 degrees can cause heart palpetations for weeks. It happened to me twice in two summers - i rode every day for five years to the same place, thru freezing and 112 plus heat. The heat is WAY more dangerous. My heart was messed up for weeks, after riding in 112 heat for 15 to one hour twice,...didn't happen three times.
@rickybosephus2036 that's your anecdote. Heat is certainly dangerous but this doesn't happen to everyone. Plenty of people still bike and do intervals mid-day all summer in Phoenix and Vegas.
*As long as it does not impact the rest of your training volume or intensity. All the heat training examples in the video are additional training, whether on or off the bike In a 3 phase training blocks you'd do some heat training in phase 2, more in phase 3
@@Mike0 Generally a by ll indoor trainings are executed without fans. At most open windows. I would not call it heat training but everybody I know are surrounded with vents. At the end I do not have problems riding in humid environment somewhat above 40C during summer.

Sorry, that last comment was from me, but somehow linked to a meeting I participated in!
So... I should shy away from low intensity outdoor afternoon workouts in the Texas summer...

You can view the research and study details such as controlled variables and study groups by viewing Dr. Christopher Minson's works on Google Scholar!

why were you riding in 112?!?! You need to get up early and get your rides done by 11am. 80-85F is fine but 90-95f is excessive.

Ha, I'm stoked when it's only 90-95😂
I always believed that indoor training with no fans and cooling in the living-room has positive effects on performance. This is a potential proof :)
