The purpose of this study was to investigate the effect of eight weeks plyometric training on anaerobic power, counter movement jumping and isokinetic strength in 15-18 years aged basketball players. This study was including 30 male Basketball players. The subjects were divided into two groups as: the experimental group (n = 15) and the control group (n = 15). The combine training (The plyometric training and techniques-tactics) was performed by the experimental group for eight weeks. The control group was performed only techniques-tactics basketball training for eight weeks. Performance measurement; WAnT anaerobic power test, 60° and 180° s-1 isokinetic leg strength: for right and left legs, multiple jumping and vertical jumping test were performed by the subject pre and post training. Within statistical analysis, the significance of differences between these groups was tested. The arithmetic mean and standard deviation were used as descriptive statistics and Shapiro-Wilk test was used for normality distribution. While comparing paired groups Wilcoxon signed rank test was performed, Mann-Whitney U test was used for comparing independent groups. Statistical significance was taken as 0.05. According to the result of comparison between groups; It was found that exercise had significantly effect on Peak Power (w/kg), Average Power (w), Average Power (w/kg) and Power Drop (w/kg) in experimental group (p < 0,05). While significant difference was found in Right leg 60° Hamstring and Quadriceps peak torch of experimental group (p < 0,05), there was no significant difference in pre- and post-training in Isokinetic leg power parameters of control group (p>0.05). In addition, significantly differences were found in free jump, 120° Squat jump and Active jump values of Vertical jump parameters for experimental group (p < 0,05).
