The aim of this study was to examine the possible differences on anthropometrics and strength performance between young basketball players with different maturity status. Thirty-one male players (12-15 years) participated in the study. Their maturity status was estimated by the years from/to their peak height velocity (PHV) and players were categorized as pre-, mid- or post-PHV. The analysis of variance showed significant differences in players’ body weight and height according to their maturity group. Players’ strength performance (1RM, SJ and CMJ) was significantly different between the maturity groups. Pearson’s correlation analysis showed a correlation between the PHV and the players’ weight, height and performance in 1RM (r = 0.74 – 0.80; p < .001) but not with the performance in the SJ and the CMJ (r = 0.19; p = .295 and r = 0.35; p = .055, respectively). In addition, the linear regression analysis showed that the PHV predicted the players’ weight, height and performance in 1RM (β = 0.74-0.80; p < .001; R2 = 0.55-0.65). The results of this study showed anthropometric and strength performance advantages for young basketball players with an advanced maturity status. These findings may have an impact on talent identification, selection and long-term development processes.
