Abstract:The purpose of this study was to evaluate the validity of between the Wingate and the RAST tests in young basketball players. The subjects were 45 young and health basketball players that participated in this study. The characteristics of the subjects were consist of: training experience of the subjects equal with 5.3 ± 0.3 years, age of they were 16.46 ± 0.37 years old, body weight equal with 72.02 ± 2.5 and BMI equal with 21.62 ± 0.54. Results of the study were shown that between of the Wingate and the RAST tests in amount of peak (max) power was significant relationship(r = 0.901; p = 0.00). Also, results of the study indicated significant relationship in amounts of average power between, average power per kg .W -1 ,pH and PCO2 in both tests ( p = 0<05). In regarding of achieved results can express that between of the Wingate and the RAST tests only in average power and peak power in young elite basketball players were a significant relationship. So, it conflict to this claim that “the RAST test can be predict drop power and fatigue indexes in elite basketball players” similar to Wingate test. Nevertheless, it recommended to basketball coaches to apply the RAST test only in direction of evaluation for average and peak powers in basketball players.
