Functional Ventilatory Profiling for Dynamic Reading

This article is not a literature review on ventilatory physiology. It presents an interpretive framework I have developed over six years of repeated measurements — around 80 WorldTour and ProTeam athletes profiled, twenty in longitudinal VST monitoring, hundreds of monitorings per year. The proprietary indices I present — ICIF, IMD, ECFI, IPV — did not emerge from theoretical intuition. They emerged from recurrent patterns that published markers did not describe. The article positions them as bridges between static capacity and dynamic use, to be read in pairs within a framework of discriminants. And it explains why this measurement architecture is inseparable from the VST project — the ventilatory driver that produces, on the 48-week cohort, the bulk of the gain in watts at ventilatory thresholds.
