You record the values of each stage. Plenea calculates the thresholds according to several models and derives the training zones. At the retest you see whether the thresholds have shifted. This works for lactate tests and, if your practice has enabled it, for cardiopulmonary exercise testing (CPET) too. Spiroergometry is in beta: we agree activation and supported workflows with your practice; professional interpretation remains your responsibility.
GDT files from Winlactat land in the import assistant. Before anything is taken over, you see a preview with the column mapping. If the athlete is missing, the import matches them by name and date of birth or creates a new record.
The entry assistant first asks for the type of test: lactate step test or, if your practice has enabled it, CPET. After that, everything lands in the same history of the athlete.
Plenea analyses every test according to several recognised threshold models. Curve, stage values and the training zones derived from them sit side by side. So your athlete trains in zones from their own test instead of a rule of thumb.
Compare saved tests and curves. Different protocols, daily condition and measurement conditions can affect results. A shift alone does not establish a training effect.
