Abstract

The aim of this study was to investigate the effects of sex and maturation on Counter Movement Jump (CMJ) performance in early adolescents. Forty-five students, twenty-three boys (age 12.5 ± 0.29) and twenty-two girls (age 10.5 ± 0.32) near the age of peak height velocity (PHV) participated in this study. Jump height (Height), peak power (Pmax) and maximum vertical force (Fmax) were evaluated on a Kistler platform. It was performed a mixed model repeated measure analysis of variance (RM ANOVA) to determine the interactive effects of sex (males vs. females), and maturity (18 months before PHV, 9 months before PHV, at PHV) for the Height, Pmax and Fmax (dependent variables). Girls exhibited greater relative Fmax (Fmax/weight) than boys 18 and 9 months before PHV, since boys exhibited greater relFmax near PHV. Additionally, boys exhibited greater Pmax compared to girls, mainly near PHV and higher jump height but they revealed a plateau in jump height progress near PHV. Both sexes improved jump performance near PHV. In conclusion, maturity affects vertical jumping performance in a different way for boys and girls in early adolescent.
