简要总结
Shoulder injuries are usual in volleyball players. Nowadays, few prospective studies assessed risk factors of shoulder injuries in this sport. So, the objective of this study is to assess the risk factors of injuries in youth volleyball players. For that purpose, the following factors will be taken into consideration : shoulder internal/external rotators strength, shoulder range of motion, scapular dyskinesis, functional tests (medicine ball throw and upper quarter Y balance test), training load and psychosocial factors (POMS questionnaire).
详细描述
About 100 youth volleyball players (13-20 years), playing at least 8 hours volleyball in a week will be included in the study.
At the beginning of the 2019-2020 season, they will have to take part at the following evaluations :
- Clinical evaluation :
- Scapular dyskinesis assessment (normal, subtle abnormality and obvious abnormality)
- Scapular upward rotation at 0°, 45°,90° and 120° with an inclinometer.
- Rounded shoulder posture
- Posterior shoulder stiffness
- Internal/external rotation range of motion (at 90° of abduction)
- Medicine ball throw :
From a cocking position, players have to throw a 800g medicine ball as far as possible (3 trials). Only the best result will be retained for analysis. Volunteers have 2 minutes of rest between trials. 3. Upper Quarter Y Balance Test :

结局指标
主要结局
Internal/external rotators strength
时间窗: 1 month
Strength of internal and external rotators will be assessed in concentric (60°/s and 240°/s) and in eccentric (60°/s) modes with an isokinetic device (Cybex Norm).
Medicine ball throw
时间窗: 1 month
A 800g medicine throw will have to be thrown as far as possible and the score will be measured in meters
Psychosocial factors
时间窗: up to 8 months
Questionnaire POMS will have to be filled in by the participants each month
Shoulder injuries
时间窗: up to 8 months
Participants will have to mention each month the injuries or pain they had during the previous month at shoulder location
Shoulder internal/external rotation range of motion
时间窗: 1 month
Range of motion will be measured in degrees
Scapular dyskinesis
时间窗: 1 month
"yes/no" method
Upper Quarter Y Balance test
时间窗: 1 month
The score obtained will be measured in cm and normalized by upperlimb length
