Are the thresholds the same?

They are similar but not quite the same.

Lactate is a product of metabolism. It is produced in the muscles.

​​​

Ventilation thresholds directly measure the energy system that the athlete is using.

VT2 - a performance predictor

Ventilation thresholds are more reproducible than lactate thresholds because they are easier to measure and less dependent on external factors.

​

Scientific studies by Poole & Jones (2021), Wasserman, and others show that VT2 is a predictor of performance.

More reproductible

Les tests ventilatoires mesurent directement la respiration et les transitions métaboliques.

​

Ils sont moins sensibles à des facteurs externes comme la température, le stress, la nutrition ou la méthode de prélèvement

​

Simpler and easier-to-implement protocols

Lactate testing protocols (LT1/LT2):

  • Blood sampling,

  • Sensitive to nutrition, stress, and testing conditions.

  • Lactate testing is difficult to reproduce and can yield variable results depending on the operator and environment.

  • ​​

Ventilation testing protocols (VT1/VT2):

  • Via respiration: non-invasive, continuous method

  • Directly linked to metabolic transitions.

  • Much higher reproducibility, validated by scientific literature.

​

​

With ZoneX, respiratory measurement can be performed outdoors, uphill, or on a home trainer, which better reflects actual performance.​

ZoneX offering is similar to lactate

ZoneX works financially in a similar way to lactate testing:

You buy a device, which is the starter pack.

Each test incurs usage costs (in the case of lactate, test strips, needles, etc.): €36/test.

​​​​

A ventilatory test is more expensive than a lactate test.

If you resell tests, a ventilatory test can be resold at a higher price than a lactate test:

Less invasive.

More reliable.

More accurate: shorter and closer plateaus.
