Years later I found this video and it is still amazing. Thank you very much for the explanation! I happened to watch another video about "priming" before a race (2-30 minutes in duration). So what priming effectively does is reducing the Time Delay at the start of the race and gets us far quicker into the steady state. Is that correct?

Thanks Mark for all the content. Well explained and presented with joy! Many thanks again ❤

I used priming on my last 5k race, felt relaxed the whole way and was still faster. Thanks for sharing Mark 💪😎

Hello Mr, thank you very much for the very pedagogical presentation. I don't know if I've missed the information, but would you have the reference for the data from the hyperbolic function you present between 2:17 and 3:54?

Cool, but what can I do to be more fatigue resistant?

Thank you for this informative video... Can you make a video on how to do the analysis on software? the fit curves, calculation of tau, etc... it would be great if a real-life example is being analyzed...

It's basically an 1min all-out sprint directly followed by a 2min all-out sprint. I think I would rather cut my legs off. 😛

What does the HR graph look like? I can't imagine reaching max HR in 60 to 90 seconds from a cold start, yet VO2 max is reached that fast?

Fascinating that scientists haven't established the cause, as of the date of this video, maybe even today in 2024.

That's fantastic. Thank you!

thakns a lot for your videos. I'm a sport scientist student who loves these in detail videos. keep it up!

Hello, can we get better accuracy by using 10-minute increments for the tests, or should we use increments between 4 and 6 minutes?

For those of us that dont whant to have lab work done. How do we know what HR to train at. My HR is all over the place because I'm training on trails with hills for 10 miles (1400 ft gain and loss 5 miles out and 5 miles back) and I sometimes do the 10 miles twice. My average HR if I take it easy with no running is 124 bpm and that's about 3hrs. If I add running on the flats I do it in 2:38 with an ave HR of 148. Is that 148 good for a 2:30 time or should I push even harder for a 150 HR average or less or what? My max HR that I can get to is about 183 but I dont do that very often. I'm also 68 years old but I feel like I should be able to do much more. I'm also Keto and near carnivore because every time I try eating carbs for any length of time my A1C climbs up to over 5.6. As I am I can hike slow for 12-15 hrs a day and hike 22-28 miles

thanks for the very clear explanation! can I ask to you where I can find formulas to calculate CP from different efforts? like from sprint, 3' and 6' all out? please? thanks!

16 minutes = 480 watts on the incremental bike test- nice!

Hi. Thanks for the great lecture. Just as a feedback - please tune up the volume of the voice, otherwise the advertisement is incredible loud. One question to the content: last slide --> which parameter would you use to set the load for a constant load test, if %VO2max an %Peak Power is "not allowed"? thank you!

This is a very interesting topic. I am interested in how this may fit into a hard training week. Say if you train hard, and go anaerobic on Tuesday and Thursday, then have Friday easy or off, and race (or parkrun) on a Saturday, will your glycogen still be depleted from the efforts in the week? If you are starting with slightly depleted glycogen, or fatigue from a normal week's training, will that impact the advice on the best warmup for a 5 or 10k race or parkrun on Saturday?

Amazing work!

What an awesome presentation! Much appreciated!! Thank you

LC is not a "post-viral fatigue syndrome." It is a post-viral syndrome affecting every single organ and system in the entire body, and unnatural energy is a symptom as often as debilitating fatigue. An exercise physiologist is the WORST person to be talking about LC, given the history of the gaslighting and abuse of MECFS patients. The bulk of LC is actually Mast Cell Activation Syndrome, the dysregulation of the inflammatory response. MCAS can make exercise incredibly dangerous for some people, though not for everyone, since each person's innate immune system is completely individualized. Want to help people with LC? Then literally never connect it to exercise. The history of exercise as a "treatment" for MECFS shows that capitalism ruins EVERYTHING, including healthcare. GET has been pushed on MECFS patients as part of a far-reaching effort to prevent the general public from understanding MECFS, to spare insurance companies the indignity of actually having to connect patients with healthcare, and to obscure how little medicine truly knows about the innate immune system and thus the human body and ESPECIALLY mental health and consciousness. No patient will believe your nonsense. You can't gaslight people in a way that denies them access to LITERALLY ALL OF LIFE without making them despise you. If you begin your intro by saying how oblivious you are about all of this nonsense, you're...not really going to establish any credibility, since post-viral illness in general has been around a very, very long time, and anyone who knew what they were talking about would immediately be able to understand at least the BASICS of LC.

excellent. Thank you very much.

Thank you for this vidéo. I have a question regarding how to run this test. I found in the literature that the subject can stand up (not be seated on the chair of the ergo cycle) while performing the test and this is in order to give its maximum. But in my case, the subject must remain seated on the ergo cycle chair while performing the test. In other words, the subject will try to perform at their maximum while remaining on the chair. Do you think the test will be meaningful in this case?

I am an exercise physiologist, who performs such tests on a regular base. I don't see often the described patterns. For example - sometimes there is no ve\vo2 gain, the ve pattern is also different

anaerobic glycolysis consumes 18x times more carbohydrates as aerobic to generate ATP. So a bad lactate threshold is an indicator of fast glycogen depletion. this matters even more than the slow component

Very interesting, thank you for another video. Looking forward to your next one :)

Great video ! thank you mark.

What? Someone got a cheetah to run on a treadmill? That's taking herding cats to a level I'd never even contemplated.

I'm so glad that I found this video and your channel, Mark

Thank you for sharing this info with us.

Seems to be quite a nonsense. As the velocity at VO2max in running can be hold for 5-8 minutes, it is clear that a 3 minutes test would provide an even higher velocity as vVO2max. But CP is below vVO2max. So this is falsified.

Do you find many outliers who cant hold CP for 30 mins plus ? and is it standard practice to test time to exhaustion at CP to test the CP for an indvidual is correct in a study?

I really struggle to grasp my lecturer’s way of teaching so your videos have been such a big help to me. Thanks!

I really like your channel but am not quite up to scratch with everything you talk about. To start a journey of exercise physiology where do you think I should start

RIP All-Out Physiology! This was a great channel.

Sir I wanna do MSc in exercise physiology. In your opinion which university is among three is best Leeds Beckett University or Liverpool John Moores University or University of Brighton.

Thank you for this and all of your other great videos! I have a quick question. If you fit a CP model using the 1/time-power relationship, what would you consider a minimal R2 to deem the model a good fit? Thanks!

So this is the mechanism behind why the 2nd and 3rd vo2 intervals feel better than the 1st in a set? Really interesting. Thx for sharing.

What do you think about Bart Kay’s ideologies of exercise physiology?

The explanations are superb. Thankyou.

Memorable classic at 12:20, seems a lot like reading tea leaves…thanks for educating and entertaining.

Thankyou very much for this masterclass: fascinating, clear and entertaining.

Fascinating stuff, gripping - I just wish my mathematics was a bit more sophisticated. I really appreciate how much effort has gone into these masterpieces.

This is very interesting. Are you planning on a follow-up to explain the best training methods to enhance fatigue resistance? Pros appear to be very focused on this during winter training by spreading some intensity (intervals) during longer rides. Many amateurs are doing the exact opposite by performing short duration high intensity sessions to raise FTP. Of course many pros know their FTP ceiling, respect it, and hence focus on other training

3:37, I enjoyed the joke.

Your channel saves me! --from a new exercise science MS student.

Learnt A lot !!!! Thaank

Very good video, thank you for the information!

I don’t think I’d feel confident saying “venous po2” several times without a Freudian slip. Good job 😅👌

Thank you that was explained so well. If I wanted to calculate a VO2 max without any equipment, as accurately as possible say, how would I do that?

As i know, vo2peak is the highest 1s value of the gas analyzer, and vo2max - the 30s average
