Summary

This observational study looks at whether pre-adolescent football players born earlier in the selection year perform better on a passing test than those born later. Around 61 children from a youth development programme in Colombia take the Loughborough Soccer Passing Test, which measures speed and accuracy. Researchers then compare results across birth quarters to see if relative age influences performance.
