Methods. Sixteen volleyball players, Eltayaran club, divided into two groups. The experimental group (n =8) take boron supplement contains boron mineral salts the boron supplement has been taken in a daily dose(2MG) in the last 4 weeks in the program for the experimental group.

Subjects were required to read and complete a health questionnaire and informed consent document; there was no history of injuries, diabetes or recent surgery.Results. The results showed statistically significant differences:1. between the experimental group and control group in Free Testosterone After effort for posttest to the experimental group. No Significant Difference Free Testosterone at rest2. between the experimental group and control group in Leg Static strength, Back Static strength, Vertical Jump, Seated Medicine Ball Throw for posttest to the experimental group Conclusion. In conclusion, our data suggest that (4) weeks boron supplementation could improvement of Free Testosterone After effort, Leg Static strength, Back Static strength, Vertical Jump, Seated Medicine Ball Throwin volleyball players.
