What is Maturity-related developmental inequalities in age-group swimming: The testing of ‘Mat-CAPs’ for their removal about?

## Objectives: To (1) examine the association between maturity timing and performance-based selection levels in (n=708) australian male 100-m freestyle swimmers (12-17 years); (2) identify the relationship between maturation status and 100-m freestyle performance; and (3) determine whether maturation-based corrective adjustment procedures (mat-caps) could remove maturation-related differences in swimming performance. ## Methods: In part 1, maturity timing category distributions ('early', 'early normative', 'late normative' and 'late') for 'all', 'top 50%' and '25%' of raw swimming times were examined within and across age-groups. in part 2, multiple regression analyses quantified the relationship between maturity offset (yphv) and swimming performance. in part 3, sample-based maturity timing category distributions were examined based on raw and correctively adjusted swim times for 12-17 year old age-groups. ## Results: Based on raw swim times, a high prevalence of 'early-maturing' swimmers, with large effect sizes was identified (e.g., 14 years 'all' - χ (3, 151=111.98, p<0.001; 'early' v 'late' or=82.0 95%ci=4.77, 1409.9); while a complete absence of 'late-maturers' was apparent i
