Who are the Eurofittest?

Area of Science:

• Pediatric Exercise Science
• Sports Medicine
• Public Health

Background:

• Previous research focused on aerobic fitness disparities in European youth.
• Limited understanding of geographic variations in other fitness components among children and adolescents.
• This study aggregates Eurofit data to explore cross-European fitness differences.

Purpose of the Study:

• To describe geographic variability in European children's and adolescents' fitness test performances.
• To analyze differences in fitness components beyond aerobic capacity.
• To identify potential factors influencing these performance variations.

Main Methods:

• Meta-analysis of 67 studies reporting Eurofit test data for European children and adolescents (ages 7–18).
• Data standardization using z-scores relative to age- and sex-matched peers across all countries.
• Monte Carlo simulation used to generate pseudodata and combine raw data.
• Calculation of sample-weighted mean z-scores for each country.

Main Results:

• Analysis included 1,185,656 fitness test performances from 23 European countries.
• Significant variability observed in mean z-scores among countries, varying by fitness test.
• Children from northern and central European countries exhibited superior performance, averaging 0.3–0.4 standard deviations above the European mean.

Conclusions:

• Fitness performance in European youth is not uniform across geographic regions.
• Socio-cultural factors, including the societal emphasis on exercise and sport, are associated with observed performance differences.
• Further research into the impact of cultural context on youth physical fitness is warranted.
