The purpose of this study was the effect of functional fatigue dynamic balance in girl students with different plantar arch. To measure the subjects' foot arch was used the navicular drop test. Then The 75 students who were selected at random and targeted in three groups twenty five people 1- Group with normal foot arch 2- Group with flat foot arch 3- Group with cavus foot arch were placed. Pre-test SEBT, fatigue protocol (20 minutes activity in 7 stations) and pos-test SEBT Was performed. To determine quantity of fatigue was used Borg (RPE) scale effort of perception before the first station starts, End of the third station and Just after finishing seventh station. The data is analyzed in significance level .05 by the use of Spss17 software and dependent t test, One-way ANOVA and Scheffe's post hoc test. The results showed a significant difference between pre-test and post-test scores dynamic balance in all three groups (P=0.004). Scheffe's post hoc test showed that there is a significant difference between the mean difference between pre-test and post-test scores in the balance Group of normal foot arch with Group of flat foot arch and Group of cavus foot arch (P<0.05). Due to the significant reduction in the balance of subjects with abnormal arch, so the correct of abnormality foot arch and use of appropriate training courses to improve their physical fitness is recommended.
