OBJECTIVE: To evaluate the effectiveness of neuromuscular training in reducing the rate of acute knee injury in adolescent female football players. DESIGN: Stratified cluster randomised controlled trial with clubs as the unit of randomisation. SETTING: 230 Swedish football clubs (121 in the intervention group, 109 in the control group) were followed for one season (2009, seven months). PARTICIPANTS: 4564 players aged 12-17 years (2479 in the intervention group, 2085 in the control group) completed the study. INTERVENTION: 15 minute neuromuscular warm-up programme (targeting core stability, balance, and proper knee alignment) to be carried out twice a week throughout the season. MAIN OUTCOME MEASURES: The primary outcome was rate of anterior cruciate ligament injury; secondary outcomes were rates of severe knee injury (>4 weeks' absence) and any acute knee injury. RESULTS: Seven players (0.28%) in the intervention group, and 14 (0.67%) in the control group had an anterior cruciate ligament injury. By Cox regression analysis according to intention to treat, a 64% reduction in the rate of anterior cruciate ligament injury was seen in the intervention group (rate ratio 0.36, 95% confidence interval 0.15 to 0.85). The absolute rate difference was -0.07 (95% confidence interval -0.13 to 0.001) per 1000 playing hours in favour of the intervention group. No significant rate reductions were seen for secondary outcomes. CONCLUSIONS: A neuromuscular warm-up programme significantly reduc...
