The KOAR BIO technology

Garment woven with an active bioceramic, with mineral oxides integrated into the fiber.
Three combined mechanisms: mineral oxides, far infrared (FIR) and negative ions.
Stated goal: support sporting performance and skin microcirculation.

Protocol and population

Double-blind with the active KOAR BIO garment vs a visually identical placebo garment.
Sample: 15 athletes, each compared with and without the garment.
Incremental triangular exercise test on a cycle ergometer: +25 W every 2 minutes up to PMT.
Set-up: anthropometry, auscultation and baseline capillaroscopy.
Measures: HR, MAP/PMT, VO2, lactates, ventilatory parameters, work done, capillaroscopy.

Exercise test results

VO2 max: +2.9% with the garment (3408.6 vs 3311.4).
VO2 / HR: +2.6% (oxygen pulse, O2 transported per beat).
Lactates at 2 minutes: -8% at equal intensity.
Lactates max relative to PMT: -5%, the most marked effect of the study.
Reading: aerobic pathway used more, anaerobic shift comes later.

Capillaroscopy results

Markedly greater dilation of skin capillaries with the active garment.
Improved skin blood circulation.
Easier thermal exchange, supporting thermoregulation during effort.
Effect observed at the skin level; the study cannot conclude at the muscle level.

Statistical robustness and limits

% error risk (garment effect vs learning effect): Lactates max/PMT 11.2% vs 44.8%; VO2 max/HR 23.0% vs 53.1%; VO2 max 22.7% vs 48.6%; Lactates 2' 16.1% vs 15.3%.
On most markers, garment-related differences are clearer than the learning effect.
Limited sample size: results remain exploratory.
No medical, therapeutic or guaranteed performance effect is claimed on this basis.
