Clinical Trial Summary

Background: To assess the impact of pre-season clinical measures and rotator muscles strength on the risk of significant shoulder injury (SSI) in elite badminton players Design: Prospective cohort study Participants: Nineteen elite adolescents badminton players were included and followed over the badminton season (from september 2018 to may 2019 and/or from september 2019 to may 2020) .

Independent variables: A pre-season visit consisted in clinical and isokinetic shoulder strength testing. Clinical testing consisted in the shoulder range of motion (ROM) measurements and the table-to-acromion distance (TAD)Isokinetic internal and external rotator shoulder muscles strength was tested at 60 and 240°/s. Conventional and functional (eccentric-to-concentric) ratios (FR) were calculated. SSI collection was performed by an experienced sport physician.

The population was all the elite badminton players followed in a University Hospital Centre and the National Institute of Sport, Expertise, and Performance. We excluded players who had SSI in the 3 months prior to the isokinetic test or had shoulder surgery. They were included and followed during the badminton season (Nineteen elite badminton players and followed over the badminton season (from september 2018 to may 2019 or from september 2019 to may 2020)

Primary	Baseline Isokinetic strength testing (ratios)	Shoulder rotator muscles isokinetic strength test, Measures: ratios between external rotator muscles (ER) and internal rotator muscles (IR) (ER:IR), in percent (%)	one preseason evaluation (september 2018 or september 2019)
Primary	Clinical measurements, ROM	Shoulder internal and external rotation range of motion (ROM)	ne evaluation, one preseason visit (september 2018 or september 2019)
