Calculating LT1 and LT2 approximately without a blood test?

No you are not. As I said earlier I know what is easy (100W) and I know what is hard (200W), As to when it actually changes from easy to hard I really don’t have much idea. Perhaps I should just split the difference?:grinning:

Yeah, his podcast requires a bit more focus than others. I can’t listen to it unless it’s an easy ride. Maybe tomorrow.

fyi w/rt muscle fibre recruitment

@sryke that’s why I said this

I have no clue what’s going on, just believe it (appears to help) increase performance. Or not. Who knows :man_shrugging:

only thing I really believe in is volume. Today was 2.5 hour endurance Tuesday :metal:

Nice to see lots of people taking a shot at a Nobel Prize.

Before anyone asks. A lot of the questions answered(!) in sports physiology would justify a Nobel for actually answering them.

Most important part of the podcast FOR THIS THREAD:

1:33:10 into the episode. Is there a way to get that with power? (or does it even matter) That is primarily what this thread is about. Yes, you don’t have to seek out MLSS using lactate. We have FTP, CP, etc. Power FTW.

I want a target(s) for training that I spend most of my time in. I don’t spend most of my time at FTP, CP, or any other medium to high intensity level. Not because of some misguided notion of intensity distribution but because that’s just good endurance training. You have to. Fatigue, etc. I absolutely train (or have trained) in those other areas. We have some pretty well-defined ways of getting at those levels.

Ppl spend a lot of time talking about what we all do the least. We all do it. I want to understand better ways of doing what I—as an endurance athlete—do the MOST, the lower intensities. LT1? LT-blah. whatever. What’s going on there, if anything?

“There is no ‘LT1’, ‘LT2’, etc. - only a continuous but non-linear relationship between exercise intensity and muscular metabolic strain.”

There ya go guys. Santa Claus isn’t real. :slight_smile:

LOL. Good one. I’m not on twitter but judging from the date looks timely.

Assuming @empiricalcycling feels the same? It is what I expected but wasn’t sure and never good to assume. Also thought maybe there is some nuance. :man_shrugging: Well, we know where Coggan stands and he conveyed it with a nice level of directness and brevity. :+1:

FWIW, Coggan seems to be deleting his tweets after a short while. I’m looking forward to the Coggan interview on the Empirical Cycling podcast. Kolie keeps promising it.

Except for WindWarrior. Have you seen the VI and lack of decoupling on his outdoor rides? He’s a turbo trainer…in ERG mode LOL

:robot: just trying to reduce my carbon footprint by doing workouts outside… My coach calls me Steady Eddy sometimes LOL.

All-or-none switch-like activation is very common in biology. These biological switches are based on molecular interactions that form postitive feedback loops. However, at all spatial and temporal scales we find binary regulatory elements between two stable states.

How do you reconcile that statement with, if I understand correctly, that muscle fibers are always producing some lactate even when at rest. That doesn’t appear to be an all-or-none situation, and hence your 3rd sentence although its not clear in my mind of the two stable states when using blood lactate as a marker.

I made a general comment about the existence of switches in living organisms or ecosystems. I did not say that all biological systems are switches. Switches are components of biological systems.

Dead vs alive is pretty binary. An important switch in population dynamics, hence at a very large scale. Just one example …

Unfortunately there is such a thing. When do you declare someone on a life support machine dead? What is dead?

What’s up with his twitter? only has 1 post and 400 followers

Surely you meant to say somewhere between 40 and 70 minutes… :wink:

He posts, waits a day or so, deletes, and posts again.

Hmm that’s annoying
