Calculating LT1 and LT2 approximately without a blood test?

@redlude97

The paper for sure is only referencing LT2, its been around for awhile and discussed plenty. If there is another reference where LT1=LT2 I would be very interested.

Yep, me too. That paper (among others I’m sure) demonstrates strong relationship between LT2 and FTP.

@redlude97

My understanding is that skiba and many coaches havent really even considered LT1 for coaching since its been relatively easy to prescribe endurance work

Agree, and I think it also comes down to their belief that you don’t have to train at or near max fax oxidation to improve fat utilization. IOW, all training at or under LT (and even certain types >LT) improves fat oxidation.

@Quaestor

I don’t know how can you interpret it different. If you follow what he is saying. He never makes a distinction between LT1 and LT2. And he defines LT clearly:

I see what you’re saying @Quaestor and I’m not trying to “shoot the messenger” (you). I just think if he says LT1 ~= LT2 (for elites) I’m going to need to see more.

Look at ISM metabolic flexibility paper and in WT Pro cyclists LT1 is not LT2. But as usual, language and methodologies…also inflection point or 2mmol/L or 4mmol/L? Need to see how Skiba defines.
