The aim of this study was to determine the effect of 8-week plyometric training on the leg power, jump and sprint performance in female soccer players. Eighteen of female soccer players from Women 2nd League (age = 18.2 +/- 2.3 years, height = 161.3 +/- 5.4 cm, body mass = 56.6 +/- 7.2 kg,) were randomly assigned to a control (n=9) and a plyometric (n=9) groups. Both groups continued together with regular technical and tactical soccer training for 4 days a week. Additionally, the plyometric groups followed by plyometric training, during 8-week in one day per week, 60 minutes session duration. During the 8-week period, the control group was hindered from any additional conditioning training. All players' jumps (triple hop, countermovement and standing broad jump), running speed (20-m) and peak power were evaluated before and after 8-week. No significant difference was found between groups at pre-test variables (p > 0.05). Significant improvements were found to all of the post-test of the both groups (p < 0.05) except 20-m sprint test of the control group (p > 0.05). Triple hop distance, countermovement jump, standing broad jump, peak power and 20-m sprint test values were all significantly improved for the plyometric group, compared with the control group (p<0.05). We concluded that short duration plyometric training an improved important component of athletic performance in female soccer players. The results indicate that safe, effective and alternative plyometric training can be useful to strength and conditioning coaches, especially in competition season where less time is available for training.
