Research Article: Relationship between a daily injury risk estimation feedback (I-REF) based on machine learning techniques and actual injury risk in athletics (track and field): protocol for a prospective cohort study over an athletics season

Date Published: 2023-05-16

Abstract:
Introduction Two-thirds of athletes (65%) have at least one injury complaint leading to participation restriction (ICPR) in athletics (track and field) during one season. The emerging practice of medicine and public health supported by electronic processes and communication in sports medicine represents an opportunity for developing new injury risk reduction strategies. Modelling and predicting the risk of injury in real-time through artificial intelligence using machine learning techniques might represent an innovative injury risk reduction strategy. Thus, the primary aim of this study will be to analyse the relationship between the level of I njury R isk E stimation F eedback (I-REF) use (average score of athletes’ self-declared level of I-REF consideration for their athletics activity) and the ICPR burden during an athletics season. Method and analysis We will conduct a prospective cohort study, called I njury Predict ion with A rtificial I ntelligence (IPredict-AI), over one 38-week athletics season (from September 2022 to July 2023) involving competitive athletics athletes licensed with the F rench F ederation of A thletics. All athletes will be asked to complete daily questionnaires on their athletics activity, their psychological state, their sleep, the level of I-REF use and any ICPR. I-REF will present a daily estimation of the ICPR risk ranging from 0% (no risk for injury) to 100% (maximal risk for injury) for the following day. All athletes will be free to see I-REF and to adapt their athletics activity according to I-REF. The primary outcome will be the ICPR burden over the follow-up (over an athletics season), defined as the number of days lost from training and/or competition due to ICPR per 1000?hours of athletics activity. The relationship between ICPR burden and the level of I-REF use will be explored by using linear regression models. Ethics and dissemination This prospective cohort study was reviewed and approved by the Saint-Etienne University Hospital Ethical Committee (Institutional Review Board: IORG0007394, IRBN1062022/CHUSTE). Results of the study will be disseminated in peer-reviewed journals and in international scientific congresses, as well as to the included participants.

Introduction:
Athletics (track and field) activity leads to a risk of injury. 1–4 Indeed, epidemiological studies showed that about two-thirds of athletes presented at least one injury during an athletics season. 1 2 5 6 Specifically, in a French one-season athletics study, 65% of athletes reported at least one injury complaint leading to participation restriction (ICPR). 6 Another way to quantify the impact of injuries is the injury burden, defined as the number of sports activity days lost due to injury per 1000?hours of…
