The purpose of this study was to assess plantar pressure and static balance alter-ations after jumping and landing. According to the importance of devastating impact ofimproper distribution of plantar forces on the incidence of abnormal movements and stressesin the foot structure of volleyball players, studying the effect of fatigue on plantar pressureand static balance can lead to significant achievements in the evaluation of this organ’s per-formance. In this study, 12 male adolescent volleyball players with a history of unilateral ankleinjury and 12 male adolescent volleyball players without a history of unilateral ankle injury wasparticipated. Plantar pressure characteristics and static balance in volleyball players with andwithout history of unilateral ankle injury was recorded before and after a fatigue from consec-utive jumping and landing protocol while standing static on foot pressure. maximum pressure,mean pressure, pressure distribution, surface and romberg open and close eyes balance regis-tered. There was a significant difference between the maximum and the mean plantar pressureand the contact surface of the right foot before and after fatigue and significant differencebetween the mean pressure and the pressure distribution of the healthy foot and the injuredleg in individuals with a history of ankle injury also fatigue cause reduce balance in adolescentvolleyball players without history of unilateral ankle injury in open eyes mode and reduce bal-ance in adolescent volleyball players with history of unilateral ankle injury in open and closedeyes. These changes could lead to lower limb injuries.© 2019 Published by Elsevier Masson SAS.
