Measured, not estimated.
Two methods, one picture of your endurance : spiroergometry measures your VO2max and the ventilatory thresholds, lactate diagnostics confirms them along a second, independent route. What you end up with are your real training zones.
Your VO2max, measured directly.
Gas exchange under load.
Through a mask we measure oxygen uptake and carbon dioxide output while the load rises step by step. That gives us your maximal oxygen uptake and the two ventilatory thresholds VT1 and VT2.
- VO2max in ml/kg/min, placed by age and sex
- Ventilatory thresholds VT1 and VT2
- Heart rate and wattage ranges for every intensity
- Analysis in a personal conversation, plus the written report
Treadmill, bike, rowing or ski erg.
The test runs on the device that matches your sport. That makes the values transferable to your training instead of to a movement you never do.
The second measurement, from blood.
Step test with a lactate curve.
After each stage we take a drop of blood from the earlobe. The course of the lactate values gives us the thresholds LT1 and LT2, which separate your base and threshold ranges.
- Lactate thresholds LT1 and LT2 from the measured curve
- Cross-check against the ventilatory thresholds from spiroergometry
- Zones in watts, pace and heart rate, usable in training
- A retest under the same conditions shows whether the training works
Training zones, without the guesswork.
Why smartwatch zones mislead you and how real, measured zones make your endurance training precise. A short look from practice. The clip is in German.
Four steps, one test day.
From booking to the finished report. The measurement itself takes about an hour.
Briefing
A short conversation about your training status, goals and medical history. After that the device and the step protocol are set.
Testing on site
Step test at CrossFit Tübingen, with gas exchange analysis, lactate sampling or both. About 45 to 60 minutes including the briefing.
Analysis
Your curves, thresholds and zones in a written report, plus the explainer video that walks you through it page by page.
Putting it to work
We go through what this means for your training. On request with training planning or as the baseline for ongoing support.
Single test or the full picture.
Both methods together give the complete energy system profile. Measured separately you get the respective section.
