Abstract

Introduction: The application of contemporary statistical approaches coming from Machine Learning and Data Mining environments to build more robust predictive models to identify athletes at high risk of injury might support injury prevention strategies of the future. Purpose: The purpose was to analyse and compare the behaviour of numerous machine learning methods in order to select the best performing injury risk factor model to identify athlete at risk of lower extremity muscle injuries (MUSINJ). Study Design: Prospective Cohort study. Methods: A total of 132 male professional soccer and handball players underwent a pre-season screening evaluation which included personal, psychological and neuromuscular measures. Furthermore, injury surveillance was employed to capture all the MUSINJ occurring in the 2013/2014 seasons. The predictive ability of several models built by applying a range of learning techniques were analysed and compared. Results: There were 32 MUSINJ over the follow up period, 21 (65.6%) of which corresponded to the hamstrings, three to the quadriceps (9.3%), four to the adductors (12.5%) and four to the triceps surae (12.5%). A total of 13 injures occurred during training and 19 during competition. Three players were injured twice during the observation period so the first injury was used leaving 29 MUSINJ that were used to develop the predictive models. The model generated by the SmooteBoost technique with a cost-sensitive ADTree as the base classifier reported the best evaluation criteria (area under the receiver operating characteristic curve score = 0.747, true positive rate = 65.9%, true negative rate = 79.1) and hence was considered the best for predicting MUSINJ. Conclusions: The prediction model showed moderate accuracy for identifying professional soccer and handball players at risk of MUSINJ. Therefore, the model developed might help in the decision-making process for injury prevention.
