SHAP-based interpretable machine learning for injury risk prediction in university football players: a multi-dimensional data analysis approach
This analysis explores a novel approach to predicting injury risk in university football players using interpretable machine learning. By constructing a comprehensive multi-dimensional feature system and employing SHAP values, we aim to move beyond traditional black-box models, identifying key risk factors like stress and sleep to inform evidence-based prevention strategies and enhance athlete well-being.

Machine Learning Performance
Our study systematically compared 10 mainstream machine learning algorithms for university football player injury risk prediction. The Support Vector Machine (SVM) achieved optimal performance with 95.6% accuracy, 95.7% F1-score, and an impressive 99.2% ROC-AUC. This demonstrates SVM's high reliability in identifying high-risk injury athletes, effectively balancing precision and recall, crucial for clinical screening tools. While other ensemble methods like Random Forest also performed well, SVM consistently excelled across multiple metrics. Naive Bayes, despite slightly lower accuracy, achieved the highest ROC-AUC and PR-AUC, indicating strong discrimination between high-risk and low-risk samples.
Confusion matrix analysis further revealed SVM's ideal pattern with minimal false negatives (2 cases), essential for preventing missed diagnoses of high-risk athletes. Decision Tree, in contrast, showed significant limitations due to overfitting, highlighting the need for more robust algorithms in complex multi-dimensional datasets. The strong calibration (Brier score 0.044 for SVM) indicates that predicted probabilities align closely with actual injury rates, providing trustworthy quantitative risk estimates.
Key Feature Importance
SHAP interpretability analysis identified the most influential factors contributing to injury risk. Stress Level Score ranked first (importance: 0.10), indicating psychological stress as a core determinant of injury. Sleep Hours Per Night was second (importance: 0.09), reinforcing the critical role of adequate recovery. Balance Test Score placed third (importance: 0.08), highlighting neuromuscular control.
Crucially, lifestyle factors (stress, sleep, nutrition quality, warmup adherence) collectively outweighed traditional physical fitness indicators (knee strength, sprint speed) in overall importance. This finding suggests a shift in prevention strategy priorities, emphasizing holistic athlete management. The SHAP value distribution plots reveal clear bidirectional influences: higher stress and shorter sleep duration increase injury risk, while better balance and adequate sleep are protective. These insights provide a scientific basis for developing personalized intervention strategies focusing on psychological and lifestyle management.
Ethical Considerations
Labeling student-athletes as 'high-risk' carries potential psychological and social consequences, including self-fulfilling prophecy effects where increased anxiety or altered behaviors may paradoxically increase injury risk. Stigmatization can impact playing time, scholarships, and peer perceptions. It is crucial to manage these risks by reframing predictions as 'areas for targeted support' rather than 'inevitable injury destiny'.
Confidentiality protections, stress management education, and psychological support resources are essential. Shared decision-making must preserve athlete autonomy. The goal is to empower athletes with information for intervention, not to impose labels. Future implementation must carefully consider the biopsychosocial model, recognizing the synergistic interaction of athletic, academic, and social stressors on student-athlete well-being to avoid unintended negative consequences.
Limitations & Future Work
Despite promising results, this study has critical limitations. It relies on a single Kaggle dataset, limiting generalizability across diverse populations, geographic regions, or competitive contexts. The absence of external validation on independent datasets is a fundamental barrier to clinical deployment, as models can degrade significantly when applied to real-world, prospectively collected data.
Future work must prioritize multi-center prospective validation studies with at least 2000 athletes across multiple universities and countries. Implementing dynamic risk monitoring systems with wearable sensor data and weekly micro-assessments could provide real-time risk updates, overcoming the static baseline limitation. Research into injury type-specific models (overuse vs. acute traumatic) and intervention effectiveness trials (randomized controlled designs) are also crucial to move from prediction to prevention and assess true clinical impact.

Navigating Ethical Challenges in AI-Driven Health Predictions
Labeling student-athletes as 'high-risk' carries significant psychological and social consequences. This includes the risk of self-fulfilling prophecies where increased anxiety or altered behaviors might paradoxically increase injury risk. Stigmatization from coaches or peers could affect playing time or scholarship evaluations. Our analysis emphasizes the need for careful management, reframing predictions as 'areas for targeted support,' and ensuring confidentiality to protect athlete well-being. Proactive strategies are crucial to mitigate unintended negative consequences and ensure AI serves to empower, not constrain, athletes.
