Tomkinson et al. (FitBack)
About this reference
The FitBack network pooled 7,966,693 fitness test results across 34 European countries. Standing long jump data comprised 1,345,159 performances from children and adolescents aged 6-18. Percentile curves were fitted using generalised additive models for location, scale and shape (GAMLSS), with population-weighting applied to ensure fair representation across nations. This is the most geographically diverse standing long jump normative study published to date, updating Tomkinson et al. 2018 with broader country coverage and population-weighted percentile tables.
Known limitations
- Based on European youth only — may not generalise to non-European populations or to adults
- No data available for adults aged 19 and above
- Population-weighted GAMLSS smoothing may mask country-level variation in performance
- Standing long jump protocol can vary slightly between national Eurofit implementations (e.g. arm swing rules, surface type), though Eurofit standardisation minimises this
