VO₂ max describes aerobic capacity. Lactate and ventilatory thresholds describe changes in your response as exercise gets harder. Together they can guide training, provided the report explains how each result was obtained.

VO₂ max is the highest rate at which your body can take up and use oxygen during exercise. It is one part of endurance fitness, alongside how much of that capacity you can sustain and the energy cost of moving at a given speed. A higher value alone does not guarantee a faster race.
At DVOTION, gas analysis records oxygen uptake during a progressive maximal test. The report distinguishes VO₂ max from VO₂ peak where a maximal response cannot be established. The same test also provides ventilatory information that can help guide training intensities.
A staged blood lactate profile records lactate concentration from a fingertip sample at the end of each stage. These concentrations are direct measurements. LT1 and LT2 are then identified or estimated from the response; neither is a separate substance measured by the analyser.
DVOTION identifies LT1 from the first sustained rise above the lower-intensity baseline and estimates LT2 using Modified Dmax, reviewed against the individual curve. The protocol and method affect the result. An incremental LT2 estimate is not a direct measurement of maximal lactate steady state, which requires a different testing procedure.
You do not need blood sampling to obtain useful training guidance. Gas analysis can identify ventilatory thresholds, while a blood lactate profile provides a separate view of the response to increasing workload. The two systems are related but are not interchangeable.
The standalone VO₂ Max Test uses gas analysis and does not include blood lactate sampling. Endurance Performance Profiling adds a staged blood lactate profile, followed after recovery by a separate maximal test with gas analysis. The combined report keeps lactate and ventilatory findings distinct and explains how they inform the reviewed training zones.
For an aerobic fitness benchmark and training zones from gas analysis, the standalone VO₂ Max Test may meet your needs. Choose Endurance Performance Profiling when you also want a blood lactate curve and interpretation of LT1 and LT2 alongside the respiratory findings.
Use the resulting zones as training guidance, with context from perceived effort, fatigue, conditions and your recent sessions. Both services include a written report that you can use yourself or share with your coach. The illustrative report on the assessment page uses fictional data to show how findings can become training decisions.
The standalone DVOTION VO₂ Max Test uses gas analysis and does not include blood sampling. Endurance Performance Profiling includes a separate staged blood lactate profile and maximal test with gas analysis.
Blood lactate concentration is measured directly at each stage. LT1 is identified from the curve and LT2 is estimated using the stated method, then reviewed. Training zones are derived and interpreted from the findings.
Yes. Gas analysis provides ventilatory findings that can inform reviewed training zones. Lactate and ventilatory thresholds come from different signals and should be labelled separately.
A small fingertip sample is taken at the end of each stage. Exercise intensity increases progressively. The combined assessment then includes a separate maximal test with gas analysis after recovery.
