n soccer, the lower extremity is where most injuries like to meet, with ankle and knee being the most affected areas. Many studies have reported ankle sprain as one of the most common sports injuries. Risk factors such as previous injury,  anthropocentric measures,  dominant limb,  field position,  have been documented as being associated with ankle injuries. The core stability has been suggested to prevent injuries and improve performance in athletes. The purpose of this study was to investigate the relationship between core stability(isometric endurance) and dynamic balance in soccer players with functional ankle instability.  52 male soccer players were selected purposefully using the identification of functional ankle instability questionnaire. the talar tilt test and the anterior drawer test were used to differentiate the functional ankle instability from mechanical ankle instability, (age: 21.9±1.9, Height: 174.2±4.6, weight: 72.4±5). The dynamic balance of the participants was evaluated using the Y balance test at directions of anterior, posteromedial, and posterolateral. The core stability was evaluated with trunk flexion, side bridge(both sides), and trunk extension tests. The   Kolmogorov-Smirnov test was used to determine the normality distribution. Relationships between test variables were tested by bivariate correlations,  represented by the  Pearson correlation coefficient. Statistical significance was set at p < 0.05. There were no significant correlation between trunk flexion, side bridge(right and left), trunk extension tests, and Y balance values (p > 0.05). The results of this study suggest that core stability didn’t correlate significantly to dynamic balance in soccer players with functional ankle instability. As result, it is suggested not to emphasize profoundly on core stability (isometric endurance) as a contributing factor until being proved by further studies. Functional core testing may reveal different outcomes.
