Association Between Lower Extremity Muscle Strength and Knee Loading During 180° Pivot Turn in Female Players
Bibliographic record
Abstract
Sufficient muscle strength is suggested to reduce frontal plane knee loading during change of direction maneuvers. However, it is currently not thoroughly understood if lower extremity strength is associated with increased frontal plane knee biomechanics during change of direction in youth female team sport players. The objective of this cross-sectional study was to investigate the influence of maximal muscle strength on knee valgus angle and knee abduction moment during 180° pivot turn in 106 youth female team sport players. Lower hip abductor strength, lower knee extensor strength, and higher knee flexor strength were associated with increased knee valgus. Higher knee flexor and leg press strength were associated with increased knee abduction moment. The study found associations between both decreased and increased lower extremity muscle strength and frontal plane knee biomechanics. However, these associations could explain only 20% of the variance in frontal plane knee biomechanics at best.

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.
