Data were collected over five seasons from 75 male athletes (13.9\u00a0\u00b1\u00a01.3\u00a0years; percentage predicted adult height (%PAH) 93.3\u00a0\u00b1\u00a04.6%; height 164.1\u00a0\u00b1\u00a010.1\u00a0cm; body mass 51.4\u00a0\u00b1\u00a010.4\u00a0kg) for 60\u00a0m sprint, long jump (LJ), countermovement jump, isometric leg press, 10\u20135 repeated jump test, and 50\u00a0m sprint outcomes. Linear mixed models (LMMs) quantified the individual associations of maturity status and chronological age with each outcome. Model\u2010derived fixed\u2010effect coefficients were used to apply mean\u2010 and sample\u2010maximum corrections to 60\u00a0m and LJ performances. Mean corrections were effective at reducing maturity\u2010performance relationships for the 60\u00a0m (\n                    <jats:italic>r<\/jats:italic>\n                    \u00a0=\u00a0\u22120.78 to \u22120.11,\n                    <jats:italic>R<\/jats:italic>\n                    <jats:sup>2<\/jats:sup>\n                    \u00a0=\u00a00.61 to 0.01) and the LJ (\n                    <jats:italic>r<\/jats:italic>\n                    \u00a0=\u00a00.63 to 0.01,\n                    <jats:italic>R<\/jats:italic>\n                    <jats:sup>2<\/jats:sup>\n                    \u00a0=\u00a00.40 to &lt;\u00a00.001) when the correction reflected the LMM findings.
