At Kavachi, physiology is a core part of performance development. It is not treated as background data, but as essential information for understanding how an athlete responds, adapts, and progresses. Assessment is based on internationally recognised measures such as V̇O₂, lactate, cycling power, heart rate zones, and ventilatory thresholds. Used properly, these markers help identify strengths, reveal constraints, and guide training with greater accuracy. Testing is carried out in a CASES-accredited laboratory under appropriate professional supervision, providing a credible and evidence-based foundation for performance assessment
