THE EFFICACY OF A NEUROMUSCULAR TRAINING INJURY PREVENTION WARM-UP PROGRAM IN JUNIOR HIGH SCHOOL STUDENTS
Bibliographic record
Abstract
Background Previous studies have established the efficacy of neuromuscular training (NMT) warm-up programs at reducing the risk of injury in youth in sport-specific contexts and, more recently, in a pilot study that included two Calgary junior high schools. Objective To determine the efficacy of iSPRINT (Implementing a School Prevention program to Reduce Injuries through Neuromuscular Training), a NMT warm-up program in reducing sport and recreational (S&R) injuries. Design Cluster randomized controlled trial. Setting Junior high school physical education (PE) classes in Calgary, Alberta, Canada. Participants Students in grades 7–9, ages 11–16 years (n=429), from four of twelve junior high schools in the first of three study years. Interventions The iSPRINT NMT program was taught to and delivered by teachers as a S&R injury prevention warm-up program in PE classes. Schools were randomized into the NMT intervention group or a control group (two schools per group). Main Outcome Measurements Incidence rate ratios (IRRs) were estimated using Poisson regression analyses to compare injuries between groups. Injuries were assessed by a physiotherapist or athletic therapist and included any S&R injury that resulted in inability to return to the same activity, time loss from physical activity, or required medical attention. Results Injury rates (adjusted for hours of sport participation, previous injury, and clustering by class) were significantly lower in the intervention group (n=241) compared to the control group (n=188) for all sport injury (IRR=0.48, 95% CI; 0.26–0.91) and lower extremity injury (IRR=0.38, 95% CI; 0.20–0.74). Crude time loss injury rates (IRR=0.09, 95% CI; 0.02–0.45) and knee injury rates (IRR=0.18, 95% CI; 0.05–0.66) were also significantly lower in the intervention group. Conclusions These preliminary results suggest the efficacy of the iSPRINT program in reducing the risk of S&R injury in a junior high PE context. This research will inform the public health impact of school-based injury prevention programs.

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.
