Profile
Build the controlled T0 baseline: spirometry, inspiratory and expiratory mechanics, ramp test, thresholds and system responses.
Profile · Analyse · Decide · Transfer
Find the limiter before training the system.
Two days to distinguish ventilatory capacity from ventilatory use, verify the signal in the field and decide whether VST is genuinely worth pursuing for that rider.
Performance analysis — not medical diagnosis.Any functional finding with clinical relevance requires interpretation by qualified medical staff.

Why profile first
Ventilation is not one number—and a large capacity is not automatically an efficient strategy.
Profiling asks two different questions: what can the rider’s ventilatory system produce? and what does the rider actually deploy as intensity, posture and fatigue change?
The relevant limiter may sit in inspiratory flow, expiration, ventilatory frequency, tidal-volume sustainability, gas exchange, peripheral coupling—or in the transition between them. Training begins only after that hierarchy is made explicit.
The profiling pathway
Analyse
Separate ventilatory capacity from the pattern actually deployed, then identify the probable performance discriminants.
Validate
Test whether position, gradient, route, heat, altitude and competitive posture reproduce—or change—the laboratory signal.
Decide
Classify VST as a priority, a secondary opportunity or not currently indicated. The output is an estimated margin, never a guarantee.
Prescribe
When indicated, define individual iRf / iTv / VE targets by intensity and route, plus BEFORE, DURING and AFTER strategies.
Transfer
Translate the analysis into rider cues, staff-readable priorities, field monitoring and successive recalibrations.
What is measured
Static reserve. Dynamic expression. One integrated reading.
No isolated score decides the conclusion. Each metric is interpreted in context, with its methodological limits stated in the staff report.

HNS Profiling Atlas
Proprietary indices made readable for performance staff.
The Atlas transforms the profiling dataset into a structured system-level reading. Every card states its formula, interpretation, benchmark source and validation boundary. Internal or provisional reference grids are identified as such—not presented as external consensus standards.

From profile to targets
The report does not stop at identifying the performance problem.
When the signal is robust, it becomes an individual operating framework: target frequency, target tidal volume, expected ventilation and preferred route by intensity zone.
Targets are tied to power domains and the rider’s available mechanical window.
Route is prescribed by feasibility and intensity—not by a generic ventilatory doctrine.
Preparation, effort regulation and recovery are treated as one continuous strategy.
Operational output
The profile becomes a field prescription.
This anonymised Ath-03 reference shows how controlled measurement is converted into a usable Ventilatory Performance Profile: route-specific calibration, iRf / iTv / VE targets by intensity and an explicit ventilatory-pattern transition.
- Identity replaced by a non-identifying athlete code.
- Targets remain strictly intra-subject and non-transferable.
- Every field target remains traceable to its measurement method.
The decision
Profiling is a selection tool—not a sales funnel.
A clear, actionable ventilatory limiter or inefficient dynamic pattern is present and VST offers a plausible individual margin.
A ventilatory opportunity exists, but another system or training priority should lead the performance plan.
The profile does not justify longitudinal VST at this stage. The rider leaves with the baseline and the reasons for the decision.

Scope boundary
Review the evidence base →HNS profiling is performance analysis, not medical diagnosis. Abnormal or clinically relevant findings remain under the authority of the team physician and medical staff.
