I think torque influences LT1 m8, you can park it at LT1 on the indoor trainer, but outside you slow for a car and now there is a bump and you have to add torque to keep your power then you have a temporary increase in lactate. so doing it in blocks outside just a protection
1:40 I've seen Bu do this with Blummenfelt as well, doing multiple ten minute intervals and measuring lactate after. It seemed to me not just about adjusting the interval power, but more so as a comparison between sessions. Maybe as some kind of durability metric? Just speculating here, I'm not sure on the details.
Pretty obvious why you do intervals. It breaks it up so you can do more than if you just did one effort. The shorter the effort the higher the power you can do.
If you do 10x3mins threshold you can do higher power than if you did 3×10 threshold. And much more than 30mins straight threshold. It changes as intensity x duration is what sets difficulty. Anyone can do 400w for 20seconds easily
Thank you for a cool analysis! The pauses in the LT1 workouts is because of the lactate measurements and also to get some recovery for the muscles. And the long stoptime was because of filling the bottles in the heat here. A heck of a lot of fluids and carbs consumed in those workouts 😅
For sure those 3 min rest periods between LT1 blocks make a difference. I have got up to 6×20 LT1 at around 85% FTP and not feeling burn in the legs but aerobically very taxed by the end of a ride. If I tried to do 2hr at that level Iwould be getting muscle aches and strain in my lower back, probably a result of lactate build up / acid leading to deteriorating muscle function in your legs and so you start to ‘borrow’ some help from nearby muscles which are meant to provide a stabilising function. I think the key point is your LT1 deteriorates over time if you ride at the limit. Eg you could hold max LT1 for say 40 mins but then it starts to fall gradually. So you either do higher power shorter LT1 with short recovery or you go longer at just under your initial LT1 but it becomes your LT1 power by the end of the ride. Both methods have merit in my view. The repeats at higher power may develop your ability to push torque more, especially if you do some of it at 60rpm as Jonas does.

Could be it’s mentally easier to break it up same stimulus 3 hours at @lt1 is still 3 hours @Lt1
Bro is called Storm for a reason
Does he have any family relation to Jakob Ingebritsen?
It looks like a baseline lactate session + RPE intervals rather than using the power meter.
Is Bu now helping coach the team?

He does blocks downhill?
425 Watts downhill? How?
These guys LT1 are actually quite taxing. Breaking it up is a way to keep volume up without too much fatigue.

He did those 420w DOWNHILL??

They measure the lactate’s as a comparative measure for future reference
