The aim of this study was to investigate the effects of fatigue and chronic ankle instability on dynamic postural control. Approach: Thirty physical education students (14 males, 16 females) in two groups (15 healthy age = 21.78±0.79 years, height = 168.3±5.6 cm and weight = 63.6±2.6 kg, 15 with chronic ankle instability age = 21.43±0.83 years, height = 168.4±5.5 cm and weight = 63.3±3.2 kg) participated in this study voluntary. Star Excursion Balance Test was used for evaluation of dynamic postural control. Subjects performed a functional fatigued protocol that lasted 15 min. Using the Borg scale, also measured rating of perceived exertion before, middle and after the fatigue protocol. Results: The findings indicated that dynamic postural control decreased after fatigue in two groups (p}, journal = {Physics International}, publisher = {Science Publications} }
