Eighty-one badminton players(39 boys, 42 girls; age: 12.7 ± 1.4 years; body height: 153.5 ± 10.5 cm; body mass: 48.3 ± 13.2 kg)participated in the study and were divided into pre-peak height velocity (PHV, n = 31), circa-PHV(n = 29), and post-PHV (n = 21) groups. The assessment of physical fitness included linear sprint(5-m, 10-m) and change-of-direction (CoD) speed tests using a modified 5-0-5 CoD test (CoD deficit[CoDD%]) and an on-court CoD test, as well as the countermovement jump (CMJ) test as a proxyof lower limbs’ muscle power. Pre-PHV players presented lower performance levels (p < 0.001; ES:1.81–1.21) than post-PHV in CMJ, linear sprint (5, 10-m) speed, and both CoD tests. In addition,compared to circa-PHV, pre-PHV players demonstrated moderately lower performances in the 10 msprint and CoD tests (p < 0.05; ES: 0.65–1.00). Regarding the CoDD%, no between-group differenceswere found. Irrespective of the maturity status, boys outperformed girls in CMJ (p = 0.01; ES: 0.71),linear sprint speed (p < 0.05, ES: 0.52–0.77), and the modified 505 test (p = 0.01; ES: 0.71). Findingsonly showed significant sex-by-maturity interactions for the pre-PHV group. In addition, sex-relatedperformance differences were found in favor of the boys for most measures except for CoDD%. Ourresults imply that maturity status (i.e., PHV) and not chronological age should be used to designtraining programs. Female adolescent badminton players should receive specifically targeted exerciseinterventions based on their fitness status and needs PB MDPI LK https://hdl.handle.net/10612/18934 UL https://hdl.handle.net/10612/18934 NO Fernández Fernández , J.; Herrero Molleda, A.; Álvarez Dacal, F.; Hernández-Davó, J.
