PRO FULL-STACK PROFILING
Hard science, big results
Service Description
Simply the deepest physiological scan on the market. One session, several data streams—all synchronized to pinpoint exactly where your performance breaks down and how to fix it. Why book this test? • Total visibility. Simultaneous muscle-oxygen (SmO₂ & tHb), breath-by-breath VO₂, blood-lactate tracking show what your heart, lungs, and muscles are doing every second—from low-aerobic to all-out • No more guess-and-check. You leave with iron-clad training zones and a ranked list of limiters (cardiac output, O₂ delivery, glycolytic capacity, movement economy). • Coach-ready roadmap. Overlay running economy or cycling efficiency curves on the physiological data—perfect for pairing with biomech or aero testing to build an integrated plan. What’s included 1. Acyclic ramp protocol (treadmill or bike) with real-time SmO₂/tHb sensors on multiple muscle groups. 2. Progressive lactate sampling for precise threshold confirmation. 3. Full VO₂ profile (VO₂max, VLamax, FatMax, ventilatory thresholds). 4. Movement-economy/efficiency (swim, bike, run - and were you stand compared to norms) 5. 72-h report: • HR, pace, and power zones (easy → max). • Limiter heat-map and priority interventions. • Efficiency charts across intensity spectrum. • Sample micro-cycle targeting the top limiter. 6. 20-min consult to walk through findings and next steps. Pre-test checklist • No maximal training 48 h prior; light mobility is fine. • Hydrate well; no caffeine 4 h, no large meal 3 h. • Bring run shoes or bike kit (own pedals welcome). • Expect ~90 min total visit (warm-up, test, cool-down). Ideal for • Competitive endurance athletes eyeing podiums or national qualifiers. • Hybrid athletes (e.g., HYROX, XTERRA) needing clarity on both endurance and power systems. • Coaches who want a single, unified dataset instead of piecemeal lab results. Stop piecing your physiology together from separate tests. Book the PRO Full-Stack Profiling and walk away with a 360° blueprint for smarter, faster progress—delivered in just 72 hours.
