Just a question based on some thoughts about the initial query: would the site of the blood sample change the lactate measurement in a healthy person? As in ear versus finger stick or elsewhere? Just wondering others thoughts/observations as venous vs. arterial blood almost certainly differ in lactate levels, so would differing sites have that difference in levels?

I would throw in that keeping most of your body out of direct sunlight helps me immensely- I started using a Patagonia sun hoody this year for everything from ski touring to alpine climbing and it’s been a wonder at keeping my temperature regulated and it seems that I’m drinking less water when I’m out. It’s also important to remember that you need electrolytes (sodium, potassium, etc. and not ‘sports drinks’ with tons of sugar) otherwise any water you take in you’ll piss out pretty quickly without it becoming available to the cells that need it. I also am strict about not drinking alcohol as it personally messes with all my digestive hormones, insulin/glucose, and vasopressin for days afterwards. I would guess that Kilian has all those hormone systems incredibly well ‘trained’ at this point so that his body uses his water supply, glucose, intracellular salts and fatty acids in the right proportions to not need much water or food (same with Steve). I think Steve or Scott would know better about that with Kilian but I remember Ueli Steck saying he took like a power bar or two or some cheese for pretty much any day and not much water- I think he brewed up tea like once or twice on Annapurna but I actually set out what I understand he took food and drink wise and was pretty astonished at how little it was.rando_luke on June 1, 2018 at 12:31 am · in reply to: So, I borrow friends www.lactateplusmeter.com… #10124
Thanks Shane, I figured you had a controlled for fat adaptation, as a guess I would blame it on the type of exercises you did and try walking/hiking and see what values come up. As easy as unweighted knee bends and pullups are for you they’re still kind of unnatural compared to walking from a physiology perspective and therefor a little more taxing. But it could come up pretty much the same. It has me interested in possibly trying it out sometime and seeing what data I generate.
Thanks Scott, I started to test something like that about two-three weeks ago so I’ll report a little about how I feel/felt it helps when I post an athlete story sometime next month. I didn’t have too much of an issue with recovery after those but I did it mostly on rather longish days (14+ hours of hiking with climbing above 10,000′) so I was resting the next two days or so and basically just started out hiking at a pace that I couldn’t talk and breathe for 15-20 minutes then started to slow down to an all-day pace.
No issues with bonking for me but I was wondering a little about a purely climbing- oriented method to do the same thing, my buddy climbed the Nose for his first time IAD a couple weeks ago and while they made it in 19 hours they both bonked pretty hard below the last couple of pitches. He’s trying to figure out ways of preventing that short of quitting his job and moving to the Valley haha. Any ideas or insight on that would be awesome.
Would there be a greater training effect if instead of doing a high intensity workout in the A.M. then waiting until later for the long-duration exercise if you did them back to back? Let’s say the first 15-20 minutes before a training hike or run you went at a fast pace (zone 3) or did sprints for a couple minutes beforehand? And if so would it be any greater than just fasting in itself?rando_luke on May 21, 2018 at 3:48 am · in reply to: So, I borrow friends www.lactateplusmeter.com… #9988
Shane, just wondering what did you eat prior to doing the lactate test (or did you perform it fasting), like say up to 24 hrs before? If you had sugars of any kind before doing so your body is likely to primarily metabolize those first, especially doing chin-ups and knee bends. I would be interested as well to see what it looks like when you do a hiking test uphill and if the HR/lactate rate corresponds more closely to an exponential curve than a straight line.
