Ninety\u2010eight young soccer players aged 7.6\u201317.9\u00a0years underwent a 30\u2010m sprint test, anthropometric measurements, muscle thickness (MT) and maximal voluntary contraction (MVC). Maturity offset (MO) was calculated as the difference between the chronological age and estimated age at peak height velocity (PHV). Breakpoint (BP) in maximal sprint speed (MSS) development was identified at +1.1\u00a0years of MO, and the participants were classified into pre\u2010 and post\u2010BP groups. A significant correlation was found between MSS and MO in the pre\u2010BP group, but was no longer observed in the post\u2010BP group. Although step length (SL) was positively correlated with MO in the pre\u2010BP group, this correlation was not observed and step frequency (SF) showed a positive correlation in the post\u2010BP group. Multiple regression analysis revealed that in the pre\u2010BP group, leg length (LL) was the only significant predictor of MSS, primarily by influencing SL. By contrast, in the post\u2010BP group, MVC and MT emerged as significant predictors of MSS, mainly by influencing SF. In conclusion, this study identified a key developmental BP at +1.1\u00a0years of MO and demonstrated a shift in the determinants of sprinting ability from reliance on anthropometric growth before this point to a dominance of neuromuscular factors.<\/jats:p>","DOI":"10.1002\/ejsc.70133","type":"journal-article","created":{"date-parts":[[2026,1,30]],"date-time":"2026-01-30T10:31:48Z","timestamp":1769769108000},"source":"Crossref","is-referenced-by-count":2,"title":["Determinants
