Introduction: The main goal of this research is to assess the effect of whole body vibration (WBV) on muscle strength power in girl athletes.
Methodology: We intentionally selected 20 of female students. The participants were put into two groups randomly. We will give every participant a pre-test one day before the training starts to assess the dependent variables. The research factors include: leg and arm strength and power. Training on vibration machine fulfilled with 30 HZ frequency and 10 mm range at 6 different body position. Training duration on each position was 10 second that was increased by 5 second each day up to 2 minuets, between each position participant rest for 40 second. Training last 10 consecutive days. One day after the last training session we assess the research factors at the same condition for both control and training group as a post-test.
Results: Results indicate significant increase in leg and arm strength (P=0.00), the control group showed no significant change (P=0.44). Significant increase was observed in power between training groups against control group.
Discussion: When muscle or tendon are under vibrations, these movements cause muscle spindles to be motivated and prepare muscle for contraction and also increase muscle spindles sensitivity and this can give rise to the improvement of muscle reactions. Activation of muscle spindles causes tonic reflex which is located in tensional reflexive arc and this act can be seen in giving vibration to muscles.

Now days vibration training is one method in different district such as improve sport performance, rehabilitation and also
