A Novel Cutting Technique and Resistance Training Intervention to Improve Movement Patterns in Youth Female Handball Players
Bibliographic record
Abstract
OBJECTIVE: To assess whether a 9-week intervention combining cutting technique retraining and hip/calf resistance exercises reduced knee abduction moment (KAM) in young female handball players. STUDY DESIGN: Controlled laboratory study. METHODS: Forty female players (aged 15-18 years) were assigned to an intervention group (IG; n = 20) or control group (CG; n = 20). KAM during sidestep cutting and isometric strength were assessed preintervention and postintervention. The IG completed a twice-weekly program integrated into team practice. RESULTS: Group × time interaction was not significant for KAM ( P = .366) or foot strike angle (FSA; P = .171). Both groups reduced KAM ( P = .002; IG: 0.68 ± 0.16 to 0.59 ± 0.21 Nm/kg*m; CG: 0.68 ± 0.31 to 0.53 ± 0.22 Nm/kg*m) and increased FSA ( P = .040). Knee valgus angle showed no significant interaction ( P = .462) or main effects ( P = .148, P = .080). There was no interaction for hip external rotation, hip abduction, or ankle plantarflexion strength ( P≥.05). Hip abduction strength increased over time ( P = .046) without group differences. CONCLUSION: The intervention did not significantly improve KAM or strength versus standard training, though trends suggest possible effects on cutting mechanics. JOSPT Open 2025;3(4):473-482.

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.
