Predictors of Lower Extremity Injuries in Team Sports, PROFITS-study (2011‒2015)

Background

Several intrinsic risk factors for lower extremity injuries have been proposed, including lack of proper knee and body control during landings and cutting manoeuvres, low muscular strength, reduced balance and increased ligament laxity, but there are still many unanswered questions.

Aims

The overall aim of this research project is to investigate anatomical, biomechanical, neuromuscular, genetic and demographic risk factors for traumatic non-contact lower extremity injuries in young team sport athletes. Furthermore, the research project aims to develop clinically oriented screening tools for predicting future injury risk.

Methods

Young female and male players (n=508) from nine basketball teams, nine floorball teams, three ice hockey teams, and one volleyball team accepted the invitation to participate in this 4.5-year prospective follow-up study. The players entered the study either in 2011, 2012 or 2013, and gave blood samples, performed physical tests and completed the baseline questionnaires. Following the start of screening tests, the players were followed for sports injuries through December 2015. The primary outcome is a traumatic non-contact lower extremity injury. The secondary outcomes are other sports-related injuries.

Results

As this study combines measures of anatomical, biomechanical, neuromuscular, genetic and demographic factors, we will be able to study multiple factors that can predispose the player to a traumatic LE injury. Also, we can assess the relative importance of the different factors and their interactions. We will also perform risk factor analyses for specific injury subgroups, such as ACL injury, as well as other potential injury types where the number is sufficient.
