Recommending core stability exercises with the purpose of musculoskeletal injury prevention have been widespread during the last decade. It is dominantly based on the theoretical framework that dysfunction in core musculature is related to athletic musculoskeletal injuries; therefore, exercises that improve trunk musculature are connected to injury prevention and rehabilitation. To date, there is a lack of consensus agreement that could address poor core stability as a countable risk factor for sports injuries. The purpose of this study was to compare core stability between male soccer players with and without functional ankle instability. using the identification of functional ankle instability questionnaire Participants were selected purposefully. The talar tilt test and the anterior drawer test were used to differentiate the functional ankle instability from mechanical ankle instability. Core stability was measured by trunk flexion, side bridge (both sides), and trunk extension tests for both functional ankle instability (n: 52, age: 21.9±1.9, Height: 174.2±4.6, weight: 72.4±5) and intact (n: 57, age: 21.7±2.2, Height: 177.5±4.2, weight: 75.3±4.9) groups. The Kolmogorov-Smirnov test was used to determine normality distribution. The Independent t-test was used to compare the means between the groups. Statistical significance was set at p < 0.05. There were no significant differences between groups with and without functional ankle instability in the trunk flexion, side bridge(right and left), trunk extension tests (p > 0.05). The results of this study revealed that core stability was not significantly different between soccer players with and without functional ankle instability. As result, it can be noted that core isometric endurance cannot be respected as a functionally determining factor between soccer players with and without functional ankle instability. The tests used in the research were basically clinical, functional tests may reveal different results.
