One Test. A 360° Performance Picture.
Why settle for just a VO2max score? Our analysis reveals the full physiological engine driving your endurance.
-
VO2max & VLamax: Balance your aerobic capacity against your glycolytic power.
-
Fueling Insights: Know your exact Carbohydrate & Fat combustion rates for race-day nutrition.
-
Lactate Dynamics: Master your recovery, accumulation, and Anaerobic Threshold (MLSS).
-
Energy Contribution: See the percentage of aerobic vs. anaerobic energy at every intensity.
-
Actionable Pacing: Get precise training zones and interval targets based on your unique biology.
"I use VLamax as the main parameter to prepare training." > — Dan Lorang, Coach to World Champions Jan Frodeno & Anne Haug
