Differences in movement patterns related to anterior cruciate ligament injury risk in elite judokas according to sex: A cross-sectional clinical approach study
Bibliographic record
Abstract
The anterior cruciate ligament (ACL) injury stands as a significant concern in judo, necessitating preventive measures. The primary injury mechanism involves knee collapse in valgus, often linked to deficiencies in core strength, neuromuscular control, external rotators, hip abductors, and limitations in ankle and hip mobility. Sex-wise, the injury is more prevalent in women across various sports. Therefore, in the present study we observed this possible intersexual disparity in the difference of movement patterns among elite judokas according to their sex, in order to identify those athletes with a higher risk of ACL injury. Notably, there were no discernible differences between sexes in the single leg squat test. Both men and women exhibited compromised neuromuscular control in the non-dominant leg. While ankle dorsiflexion and hip external rotation showed no gender disparities, differences in internal rotation were noted. This particular movement restriction may elevate the risk of ACL injury.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
