- This is the first installment of the Evoke Endurance Book Club -- a lecture series that traverses chapter-by-chapter, the topics covered in the books Training For The Uphill Athlete, and Training For The New Alpinism -- available at Patagonia Books, and Amazon.
Here the author, Scott Johnston, lectures on the basic physiology of endurance training, and the interactions of aerobic and anaerobic metabolism involved in short- and long-duration muscular work.
What a gem of a presentation for anyone doing endurance work. Bookmarked. Thank you.
Wow . . . this makes so much sense (the big blue arrow) @29:56 Cant wait to see how you tell us how to train for that. I guess you already did later in the video. I wrote down part of it but forgot to write down the time stamp but in summary you said: *The biggest stimulus to increase the aerobic capacity of muscle fiber is glycogen depletion. The glycogen depletion triggers a whole cascade of events that take place, that end up turning on a bunch of different genes . . . which cause that muscle fiber to have more endurance in the form of more mitochondria mass (among other things). It takes a long time to train slow twitch muscle fiber (an hour or two or sometimes even three hrs for well trained individuals)*
I see now why athletes need training calendars and coaches. We need to also train fast twitch muscle and go to the gym and do resistance training, and when we do tempo training we need to recover from it and do aerobic training.
That (what you quoted above) is exactly what jumped out at me as well as I was listening to this incredible video. Makes 100% complete sense, I love this guy.
As an age group state triathlon champion (Queensland Australia) I noticed consistent results came when I dramatically increased my aerobic distances. I can physically feel in threshold interval sessions that it started to feel like I was running faster speeds breathing aerobically without knowing how this extra aerobic distance was doing this. This video answers the questions I’ve had for so long.
The main reason I believe most amateurs don’t do this is time restrictions, laziness or both. Going slow for long is both boring and time consuming, but you will never reach your endurance sport potential without spending the majority of your training doing this.
Im a distance runner who JUST figured out I have been in a cycle of burnout/aerobic deficiency ever since I tried to squeeze my training into my adult life. With a full on burnout a few years ago that made me quit the sport. I tried HIT type workouts to get 'back in shape' and just made it worse! Now I am 2 months into heart rate zone training and going 4 min per mile slower than I used to but with HOPE and Im so glad I stumbled upon your podcasts. I cant wait to hear more about your recommendations to get out of ADS. Thanks so much for sharing, its life changing, I love running and am so so glad I can do it again even if it is so much slower for now!
Thank you Scott and Evoke. This is a fabulous supplement to your book.
Thank you for putting this on your TH-cam page, I have both of your training books and to go through them again with you is awesome.
Thank you for uploading the recording. Very interesting!
This is very very interesting and helpful. Can’t wait for the next one. Thank you!
So good. Thanks Scott!
Thanks for posting, very helpful
I’m not religious (quite the opposite) but this was an epiphany for me. Brilliantly explained.
Note to self: Too much HIIT . . . talked about @54:42
At 51:37 . . . 1.5g of fat burned per minute? I burn over 700 calories per hour for 10 hours. 1.5g = 13.5 calories a minute or 810 per hour so that sounds about right. A little more training and I should be at the 800 per hr . . . My POLAR watch said I burned 7500 cal two days ago hiking up and back down a mountain trail in 10 hours. I guess it was less than that because I had a coffee with cream in the middle of that so maybe 300 were consumed calories. BUT I burned a lot more per hr going up than I did coming down so I'll have to do that hike again and use a split. I dont know how to get POLAR Flow to show me how many calories it was for just the first half (just the up hill)
Thankyou
Thanks for posting, are you going to post the following book club sessions after they happen?
