Most people want to know one thing: "Am I fit for my age?" But single-number scores, VO2max alone, and "biological age" gimmicks don't give you a real answer. PRAXIS does — by measuring five domains of functional capacity against published age- and sex-matched normative data.
VO2max tells you about aerobic capacity. It says nothing about your grip strength, your balance, your mobility, or your power output. PRAXIS measures all five domains independently, so you get a complete picture — not a single metric that hides your weak links.
Biological age calculators typically produce a single number with no transparency about methodology, no provenance on the underlying data, and no clinical accountability. PRAXIS produces a Fitness-for-Age Profile: five domain scores, each benchmarked against your age and sex cohort, each with clear provenance labelling. You can see exactly where you're ahead, on track, or behind — and so can your practitioner.
Every result carries provenance: Gold (clinician-measured), Silver (device-derived, e.g. Strava/Garmin), Bronze (self-reported). You and your practitioner always know how the data was collected.
PRAXIS provides a standardised test battery — you don't have to guess which tests to do. Your practitioner selects from a validated repertoire covering Strength, Endurance, Power, Mobility, and Balance. Results are scored automatically against normative data and compiled into a single Fitness-for-Age Profile.
Performance metrics (PBs, race times, training volume) don't tell you whether you're getting healthier. PRAXIS measures functional capacity across all five domains, so you can track genuine health improvement over time — not just performance gains in one area. Sealed reports with version history let you compare assessments objectively.
Balanced fitness means performing adequately across all functional domains, not just the ones you enjoy training. PRAXIS highlights imbalances in your Fitness-for-Age Profile — if your endurance is strong but your balance is lagging, you'll see it clearly. Your practitioner can then target the domains that matter most.
PRAXIS generates sealed, provenance-labelled clinical reports that are designed to be shared with GPs, specialists, and other practitioners. Reports carry cryptographic integrity (SHA-256), attributed audit trails, and clear domain scores — not vague summaries.
PRAXIS supports recall scheduling with built-in re-test reminders. The recommended interval depends on your goals and clinical context, but regular reassessment (e.g., every 3–6 months) allows you to track genuine change over time with sealed, comparable reports.
