Inorder to estimate the participants' dynamic balance, Star Excursion BalanceTest (SEBT) in eight directions was applied after a short warm-up.Dynamometer Isokinetic Biodex was used to execute fatigue in hip andankle joint abductor/adductor muscles. Each subject participated in twomuscle fatigue sessions. In each session, the fatigue program was randomlyassigned to one of the muscle groups of hip abductor/adductor and anklejoint evertor/inventor in repeated contractions until reaching 50% ofprimary maximum torque with the interval of 72 hours in the same situationas far as possible. Afterwards, SEBT posttest was conducted. Descriptivestatistics, dependent t test and variance analysis (with repeated measures)was used for statistical analysis at P<0.05. The isokinetic fatigue of hip andankle joint abductor/adductors significantly decreased the accessibledistance in SEBT test. Furthermore, fatigue program in the hipabductor/adductors decreased the accessible distance more than the anklejoint evertor/inventors. Due to the results, the fatigue of hipabductor/adductors was more effective in the dynamic balance of soccerplayers than ankle joint evertor/inventors.}, keywords = {Ankle Abductors,Ankle Adductors,Dynamic balance,fatigue,Hip Abductors,Hip Adductors}, url = {https://sshr.ut.ac.ir/article_36539.html}, eprint = {https://sshr.ut.ac.ir/article_36539_e0fc8cb5bce7bafef7e08eb3025797a0.pdf} }
