Spending this morning doing something I've wanted to do for a while:
Diving into the database to explore the relationship between lactate and fat oxidation
Conclusions:
For high levels of #FatBurning- you want:
* Low lactate at AeT
* High AnT relative to max
* Low max lactate

By throwing max power into the mix, I'm starting to get a nice little model together.
With most of the fat oxidation predictions on the test set within half a kcal/min of actual! e.g.

And, if you're interested in "normal" lactate numbers, here are the averages from the dataset (mean VO2max of 52ml/kg/min, 75kg bodyweight)
AeT - 170W @ 1.4 mmol/L
AnT - 238W @ 3.2 mmol/L
Max - 287W @ 7.8 mmol/L
AeT - 170W @ 1.4 mmol/L
AnT - 238W @ 3.2 mmol/L
Max - 287W @ 7.8 mmol/L
And mean fat oxidation for the group at AeT:
4.17 kcal/min
And the model prediction based solely on the average lactate data & max power....

Though, I probably shouldn't use the term "normal" to describe this (52 ml/kg) group. Maybe "desirable" is a better term.
Everything becomes relative when you're working with #Ironman athletes, especially in Boulder 😊
