Resumen de Statistical modelling for recurrent events in sports injury research with applications to football injury data
Sports injuries stand as undesirable side effects of athletic participation, carrying serious consequencesfor athletes' health, their professional careers, and overall team performance. With the growingavailability of data, there has been an increasing reliance on statistical models to monitor athletes' healthand mitigate injury risks.In this dissertation, our focus is on the statistical analysis of sports injury data, with an emphasis on thetime-varying and recurrent nature of injury occurrences. We develop and assess suitable statisticalmodelling approaches to address specific research questions that arise in sports injury preventionresearch. We pursue three primary objectives: (a) identifying biomechanical risk factors using variableselection methods and shared frailty Cox models, (b) developing a flexible recurrent time-to-eventapproach to model the effects of training load on subsequent injuries, and (c) creating dedicatedstatistical tools through the open-source R software. These objectives are driven by interdisciplinaryresearch, conducted in close collaboration with the Medical Services of Athletic Club, and are motivatedby real-world applications. Namely, the work is based on three distinct data sets: the functionalscreening tests data, the external training load data, and the web-scraped football injury data. Thestatistical advancements developed contribute to ongoing efforts in sports injury prevention, providinginsights, methodologies, and accessible software implementations for sports medicine practitioners.
