The investigation of compressive force in the new designed Beta volleyball to prevent sport injuriesBackground: One of the main causes of sports injuries is related to sports equipment and the type of ball. Thus, the purpose of this study is to investigation of the compressive force of the new designed Beta volleyball to prevent upper limb injuries among volleyball players. Methods: The present study is an applied and laboratory study. For investigation of the compressive force of the new designed Beta volleyball and compare to Mikasa, fox and old Beta volleyballs, Bertek force plate were used. Conclusion: Results obtained there were significant difference between the softness of the new designed Beta volleyball compared to fox and old Beta volleyballs in peak compressive force (P=≥۰.۰۰۱). But there was no significant difference between the newly designed ball and the standard Mikasa ball (P=۰.۷۲).Keywords: new designed volleyball, sports injuries, compressive force
