Introduction: In the last times vibration training has been used as a new alternative in sport performance. In spite of it, its long terms effects are even little known. The mean objective of this study is to evaluate the efficacy of a 15 weeks whole body vibration training program to improve lower limbs postural control and explosive strength. Design: Randomized controlled trial. Participants: 23 basketball women players of competitive level (14-18 years old). Main Outcome measures: The experimental group underwent a program training in a vibration platform during 15 weeks, with a progression of static and dynamic exercises, three times a week (vibration frequency 25-35Hz and 4mm of amplitude). It has been evaluated explosive strength by means of a countermovement jump, static balance by means of one single leg test with open and close eyes (stabilometry) and dynamic balance through one single leg hop test. All of them showed good to excellent reproducibility. Results: Vibration group increased significantly the result of the countermovement jump and one single leg hop test (p=0,00) at 8 and 15 weeks of training compare to initial test. Control group didn`t experimented any changes. There were no significant differences between 8 and 15 weeks. One single balance test with open eyes didn`t show significant changes in any group. One single balance test with closed eyes only showed significant diferences in vibration group, at 8 and 15 weeks of training compare to initial test(p<0.05). There were no significant differences between 8 and 15 weeks of training. Conclusions: Whole body vibration training increases explosive strength and postural control in young athletes. The more significant increase has been registered at 8 weeks of training
