Study population: Nineteen elite badminton players and followed over the badminton season (from september 2018 to may 2019 or from september 2019 to may 2020)

Brief 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.


Eligibility criteria: Inclusion Criteria:

All the elite badminton players from a high-level club and the National Institute of Sport, Expertise, and Performance

Exclusion Criteria:

Players who had SSI in the 3 months prior to the isokinetic test or had shoulder surgery

Primary outcomes:
measure: Baseline Isokinetic strength testing (peak torques)
timeFrame: one preseason evaluation (september 2018 or september 2019)
measure: Baseline Isokinetic strength testing (ratios)
timeFrame: one preseason evaluation (september 2018 or september 2019)
measure: Clinical measurements, ROM
timeFrame: ne evaluation, one preseason visit (september 2018 or september 2019)
measure: Clinical measurements TAD
timeFrame: one preseason visit (september 2018 or september 2019)
measure: Significant Shoulder Injury (SSI) collection (number of injury)
timeFrame: During the badminton season, the number (number, n) of injury was recorded from september 2018 to may 2019 or from september 2019 to may 2020

timeFrame: During the badminton season, the type of injury (number, n) was recorded from september 2018 to may 2019 or from september 2019 to may 2020
measure: Significant Shoulder Injury (SSI) collection (time lost from participation)
timeFrame: During the badminton season, the time lost from participation was recorded (in days) from september 2018 to may 2019 or from september 2019 to may 2020
