Direct physiological testing has been standard in professional sport for decades. Oxygen uptake measured by gas exchange. Blood lactate drawn under load. Training zones prescribed from data rather than age-based percentages.
Most athletes never get access to it. They train from wearable estimates and generic formulas, which produces inconsistent pacing and training loads that don’t match physiological reality.
Koléni applies the same testing and coaching modalities in a clinical setting, building your training program around measured physiology.
Testing is built around physiology, not sport. If you train with intention
— at any level, in any discipline — measured data tells you more than a formula can estimate.
Our diagnostic testing goes beyond estimates and algorithms, delivering medical‑grade data that reveals
how your body actually performs under stress.
Measures maximal oxygen uptake by direct gas exchange rather than estimation, establishing aerobic capacity and the ceiling your training works against.
Tracks blood lactate across increasing workloads to identify where accumulation outpaces clearance — the threshold governing how long you hold effort and how quickly you recover between efforts.
Analyzes the fat-to-carbohydrate ratio you burn across intensities, informing fueling strategy and the intensities you can sustain without depleting glycogen.
Creates physiology‑based zones derived from clinical testing rather than predictive formulas, giving you accurate targets for every session.
Wattage and pace targets for endurance, tempo, threshold, and interval work, set from measured metabolic response rather than a percentage of a past race result.
Assesses cardiac risk factors and exercise response before and during maximal effort, establishing safe intensity ceilings and identifying cardiovascular limitations that affect training capacity.
Measures recovery readiness, inflammation, and metabolic indicators that influence training capacity and how quickly you absorb hard work.
This testing is built for athletes who want to understand their physiology, sharpen their
strategy, and convert effort into measurable progress.
