Oh you’re totally right, my bad!
Relevant test methodology here
I’ve been misappropriating that term to refer to the slight drop in BLa observable from rest to low intensity. Which I see in the lab regularly enough. Resting levels maybe 1.0-1.2 mmol, and that can drop to 0.6-0.8, like San-Millán sees in Pogačar.
We also seem to notice it more in better-trained athletes. I’m not 100% sure what it represents - and it could totally be measurement error (fingertip capillary BLa with Edge or Lactate Pro). But I assume it’s related to warm-up effect and increased VO2. Get some extra mitochondria working to burn off pyruvate before La- reaches blood.
Thoughts?
