H-PRAXIS stands for: Human Performance, Rehabilitation and Athletic eXcellence through Integrative aSsessments

The sports science platform for longitudinal youth-athlete monitoring — sport-specific assessment, maturity-adjusted interpretation, and evidence-based decision support coaches can act on.

Why testing alone isn't enough

Anyone can time a sprint. A number without context is a guess.

Testing produces numbers. Development decisions need meaning — the same result read against the right peers, the right age group, and the right stage of maturation.

That interpretation layer is the platform: sport-specific, age-appropriate, maturity-adjusted, and honest about what the data does and doesn't support.

Numbers without context mislead

A 28 cm jump means nothing on its own. Against the right reference group — sex, age, maturity — the same number changes verdict entirely.

Same score, opposite needs

Two athletes with identical totals can need opposite programmes — one lacks speed, the other power. Averages hide exactly what training should target.

A snapshot isn't development

One test day is a photograph. Development is the film — the same tests, seasons apart, separating real change from day-to-day noise.

Compared with 12-year-olds55th percentile — “average”

Maturity offset per Mirwald et al. (2002).

Why biological age matters

The same jump can be average — or outstanding.

A late-maturing 12-year-old who jumps "average for his age" is often exceptional for his stage of physical development — and he's exactly the athlete traditional age-group comparison overlooks. Every result on the platform is read against biological maturation (PHV), not just a birthday year.

The platform

The lab, in your browser.

Every assessment becomes an interactive report — for the athlete, the coach and the squad. What follows isn't a mock-up: these are the product's own components, running on sample data.

The athlete report

One profile per athlete, read against three reference frames — team, chronological age, and biological maturation.

Progress that means something

Every test normalised so up always means better — including sprint times. Coaches add any test to the overall curve and separate real change from session-to-session noise.

Squad decisions, made visible

Rank the squad on any two tests and watch each player's standing shift — then split at the medians to see who needs which training emphasis. Two athletes with similar totals can need opposite programmes.

How our process works

Testing is the input. The platform is everything after.

  1. Assessment

    Sport-specific batteries, run at your club with lab-grade equipment. The only stage that happens on a pitch — everything after it is the platform.

    e.g. jumps, sprint splits, Yo-Yo — selected per sport and age group

    What we measure →
  2. Analysis

    Every result lands in a secure longitudinal athlete profile, then raw values become percentiles against international norms — by sex, age group and biological maturation (PHV).

    z-scores, LMS norms, measurement-error thresholds on every comparison

    The methodology →
  3. Interpretation

    Numbers become meaning: strengths and gaps ranked across three reference frames, real change separated from session-to-session noise, every derived value explained in plain language.

    “within typical variation” vs “meaningfully improved”

  4. Recommendations

    Coach tools turn interpretation into action: squad-level comparisons, development groups, and example training emphases per athlete — decision support, not just data.

    two athletes with similar totals can need opposite programmes

  5. Monitoring

    Re-test, and every view updates: progress curves, meaningful-change flags, development tracked across seasons. The cycle restarts — and the value compounds with every pass.

Scientific foundation

Grounded in sports science. Cited on every page.

Biological age

Two 12-year-olds can be four biological years apart. Maturity offset (Mirwald et al., 2002) anchors every comparison to development stage, not birthday.

Normative databases

Results read against published international datasets — by sex, age group and maturity stage — with the source cited on every metric.

Evidence-based interpretation

Percentiles on the full five-band scale, with the norm's confidence interval shown — the report says what the data supports, and no more.

Long-term athlete development

The battery follows the athlete across stages — what we measure changes with what matters, and the record compounds season over season.

Squad size, travel and testing frequency all change the cost, so we quote per club rather than publish a number we'd have to caveat.

Put your squad on it.

An assessment gives every athlete a report you can act on, and gives you the coach tools to compare them fairly — decisions a coach can defend.
