This morning's
#FunWithData inspired by the G-man.
I took all lactate test data and all time in zone data for athletes that I have both for and built a linear model that describes the relationship between 3 month zone 1 volume leading up to the test (in seconds) and lactate level at 250 watts.
*On a group level* for every additional 50,000s of zone 1/3mo, i.e. ~5hrs per month, lactate at 250W will decrease by ~0.4mmol/L.
This value starts to approach AeT at 500,000 seconds of zone 1 (139 hours) in the 3mo leading up to the test.
Interestingly, zone 2 volume did not have the same effect.
You ever look at the dataset and see the impact of LT1/Z1 expansion?
Thinking about 1️⃣ a volume effect, assuming a static LT1 pace/power (your 10% point above) and 2️⃣ an effect from Z1 moving to-the-right
I suspect a rightward move in my running and a need to update my HR & pace zones
