摘要：Conde JHS, Costa PL, Souza GC, Dias YR, Santos FV, Osiecki R. Maximal Strength, Speed and Isokinetic Evaluation of Power in Youth Basketball Players. JEPonline 2015;18(6):45-51. The purpose of this study was to evaluate power in youth basketball players (using an isokinetic dynamometer) and verify its relation to maximal strength and speed. Fourteen male basketball athletes (age: 15.71 ± 0.99 yrs, body mass: 74.25 ± 10.04 kg, height: 184.28 ± 6.2 cm, body fat: 10.39 ± 3.3%) performed three assessments on different days: (1) anthropometric; (2) isokinetic evaluation for peak power of knee flexors and extensors at 240°/s; and (3) one repetition maximum (1- RM) in the 45° leg press and 30 m sprint test and vertical jump. Values for vertical jump, 30 m sprint, 1-RM, power of knee flexors and extensors were, respectively: 52.5 ± 7.81 cm; 4.63 ± 0.19 sec; 340.64 ± 94.8 Kg; 193.64 ± 37.35 W and 252.81 ± 86.8 W. 1-RM was significantly related to power of knee flexors (r = 0.59) and knee extensors (r = 0.67). On the other hand, a significant correlation was found between the 30 m sprint and vertical jump (r = -0.59). Besides, physical-motor tests were significantly related to anthropometric variables. Significant associations were found between the vertical jump and 30 m sprint time, power of knee flexors and extensors as well as maximum strength in youth basketball athletes.
