Reference data

    The percentile breakpoints behind every assessment, printed in full. Each page lists the tables by sex and age band, the equation used, and the studies or surveys the numbers come from — so you can check any result yourself.

    • Waist-to-height ratio is close to sex-independent in adults, so one distribution is used for everyone aged 18 and over.

    • Distributions are drawn from resting pulse measurements in large adult survey samples, split by sex.

    • Scoring follows the original protocol: one point removed per hand, knee, forearm or side-of-leg support, half a point for a loss of balance, applied to both sitting down and standing up.

    • Two published estimating equations are used. Resting-pulse method: VO2max ≈ 15.3 × (maximum HR ÷ resting HR), with maximum HR taken as 220 − age. Cooper method: VO2max ≈ (distance in metres − 504.9) ÷ 44.73.

    • Mifflin-St Jeor: BMR = 10 × weight(kg) + 6.25 × height(cm) − 5 × age + 5 for males, − 161 for females. Total daily energy = BMR × activity factor.

    • The weighted weekly average assumes five work nights and two free nights. Catch-up is free-night sleep minus work-night sleep.

    • Office blood pressure categories as published by the European Society of Cardiology and the European Society of Hypertension.

    • rMSSD distributions narrow steadily with age. Values here reflect overnight or supine short recordings.

    • Norms are per test, sex and ten-year age band. Push-up standard: full range, body in a straight line. Plank: forearms, hips level. Squats: thighs to parallel, counted over 60 seconds.

    • Each answer carries a fixed weight in years. The offsets are summed and added to chronological age. Nothing is hidden and nothing is fitted to you individually.

    Percentiles between published breakpoints are interpolated linearly; values beyond the 10th or 90th are displayed at the edge rather than extrapolated. Read the full approach in the methodology.
