Lactate test - and zones in Xert

Support
1

Hi,
Just got a lactate test with the zones:
Active Recovery**: 0-180 watts
Light - Base Training**: 180-250 watts
Medium - Tempo**: 250-280 watts
AT - Lactate Threshold**: 280-300 watts
Vo2max**: 300-400 watts

I have used Xert before and Im considering to use it again, but Im not sure how to get the zones used in Xert for my training.

Anyone ? :slight_smile:

Xert doesn’t really use zones so you don’t need to input your results anywhere.

If you join and upload your data, assuming it’s good quality (includes max efforts across a range of durations including sprints) and has enough history, Xert will estimate your three fitness signature parameters (Peak Power (PP), Threhsold power (TP), and high intensity energy (HIE)) as well as estimate your Lower Threshold Power (LTP). That is what is used to prescribe and track training, and also predict your response to training.

Would be interesting how some of those parameters compare to your lactate results eg TP should be at or above lactate threshold (depending on how your lab defined it - there are loads of different definitions), and LTP could be around the border of base / tempo. Xert will give your more insight when it comes to ‘vo2 max’ zone as the range from your lactate test doesn’t really tell you much e.g. Xert will estimate how long you can hold 350w or 400w too

HI Wesley,
Thanks for your answer. I have been a user on Xert before, so I have just updated my activities from Strava.

My TP is 289, PP 883, HEI 17,9 and my LTP is 244. My FTP in the lactate test was 291, so I think its almost “spot on” :slight_smile:

It’s uncanny isn’t it?

Whats uncanny ? :slight_smile:

How two completely different ways of measuring your physiology come to basically the same figures. as in All roads Lead to Rome

That is actually pretty incredible how closely it predicted.
