Significant differences were identified between the approaching- and circa-PHV groups in 40-m (\n P<\/jats:italic>\n \u2009=\u2009.033,\n g<\/jats:italic>\n \u2009=\u20090.89), 50-m (\n P<\/jats:italic>\n \u2009=\u2009.024,\n g<\/jats:italic>\n \u2009=\u20091.64), and 60-m (\n P<\/jats:italic>\n \u2009<\u2009.001,\n g<\/jats:italic>\n \u2009=\u20090.89) sprint times. Countermovement jump and 50-m sprint variables were consistently important for projection of 60\u00a0m and LJ performance across the valid multivariate models.\n \n Conclusions<\/jats:bold>\n :\n <\/jats:italic>\n Large differences in performance across maturity groups highlight the importance of understanding athletes\u2019 maturity status to accurately interpret performance.
