The Endurance Ratio of Core Stability Global Muscles and Postural Control in Female Athletes with and Without Chronic Ankle Instability
Bibliographic record
Abstract
Background: Lateral ankle sprain is one of the most common injuries among athletes, which can cause chronic ankle instability (CAI) in most athletes. Objectives: This study compared the core muscle endurance ratio and static and dynamic postural control in female athletes with and without CAI. Methods: Sixty female athletes (30 with CAI, 30 without CAI) participated in this study voluntarily. McGill's test measured the endurance of the trunk extensors, flexors, and lateral flexors muscles. The stork test was used to measure static postural control and the Y balance test was used to measure dynamic postural control. Independent sample t-test was used to compare different parameters between the two groups. Results: The findings showed there was a significant difference between the two groups in flexor/ extensor endurance ratio and the endurance ratio of the dominant lateral flexors/non-dominant side. In static postural control, there was a significant difference between the two groups. In dynamic postural control, there was no significant difference between the groups in the anterior direction and the posteromedial direction, but there was a significant difference in the posterolateral direction. Conclusions: According to findings, female athletes with CAI have a lower endurance ratio in the core stability muscles and weaker postural control compared to healthy athletes. It is suggested to pay more attention to these factors in female athletes with CAI and design special exercises to prevent re-injury.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
