Nice video! Thank you Griffin!
Your point about the speed skater is interesting. I assume the speed skater finds it easier to get his Zone 2 mitochondria building training from cycling. Perhaps it's hard for him to get to the rink. I'm wondering if it makes sense for runners to get their zone 2 from cycling because it's less taxing than running. I would doubt any coach would suggest getting all zone 2 from cycling but maybe if you're doing 70 miles a week of Z2 from running it could be worth considering splitting that to just 35 miles running and maybe 12 hours of Z2 on the bike per week. I have no idea if the mitochondria from running is the same as the mitochondria from cycling.
Interesting video! What lancet do you use? Same needle for all test during a session?
Interesting!
Some research infer that MLSS seems to be more precise and efficient compared to LT2. Any thoughts on that?
I don't know the protocol to test MLSS though.
Why do you take 200 watt as your LT1 ? and not 225. what is your FTP
Yeah, this is interesting that two devices show so much difference in numbers, while differene between 0.8 and 1.3 is huge and it's still looks so low actually for 200watt. As far as i know the LT1 is consider when the lactate reaching 2.0, so you are gifted or/and in a great shape :)) Do you know if lactate amount changes when in bonk state? I mean: sometimes i have "bad days" when instead of 190w at 150 bpm - it's 120w at 150bpm and fatigue and feeling RPE of 10, like you are doing Threshold or even VO2MAX effort, do you know if lactate amount changes in this case in this zone 2 that i described above? it's interesting, because in this state every muscle in body starts to hurt
2.0mmol/l figure is an average - like HRmax being age - 220. What you need to look for is the point where lactate starts to increase, somewhere around 150bpm/200 watts and where it starts to increase steeply, around 170 bpm/250w (LT2). Physiologically LT1 would be where you start to breath more heavily but you can maintain that pace for a long period of time and above LT2 you are rapidly going to be exhausted.
Do you prick the same finger/sport every time you take a sample?
Try to keep it same hand, once you prick one spot the blood starts to clot there so that it stops bleeding which makes it difficult to stay in that spot. Self testing probably a little more difficult in getting a clean/dry sample spot. Sweat has a higher concentration of lactate, so if you go from .8 to 6.0 with not a significant increase then just try another spot! 😂
There needs to be a device worn like an apple watch that pricks your vein and gives u real-time blood lactate results😂
there is a device in development that is a wearable but they obvioulsy haven't got it to work accurately yet.
Looking for this comparison! Thanks
