To evaluate the prevalence of scapular dyskinesis (SD) in competitive swimmers during training sessions.
Repeated measurement observational study.20 young competitive swimmers were filmed before, at midpoint and at the end of a training session, performing shoulder flexion and abduction. SD was examined separately by two assessors. Demographic and Quick Disabilities of the Arm, Shoulder, and Hand questionnaires were collected.
SD was observed in 30% of the swimmers before training, in 70%, an hour later, and in 80%, upon completion of the training session. The difference between the baseline and mid-practice was close to significance (p-value = 0.055), and between mid-practice and end of practice was significant (p = 0.004).
This study confirmed that the prevalence of SD increases throughout a training session in most swimmers. The main reason might be fatigue of the muscles which stabilize the scapula, therefore, when examining a sportsmen's shoulder, it is important to examine the SD post-training or following simulation of the training session in the clinic.
评估竞技游泳运动员在训练期间肩胛运动障碍（SD）的发生率。
重复测量观察性研究。20名年轻竞技游泳运动员在训练前、训练中点和训练结束时进行肩部屈曲和外展动作时被拍摄。两名评估人员分别检查SD情况。收集人口统计学资料以及手臂、肩部和手部快速残疾问卷。
训练前30%的游泳运动员存在SD，一小时后为70%，训练结束时为80%。基线与训练中点之间的差异接近显著性（p值 = 0.055），训练中点与训练结束之间差异显著（p = 0.004）。
本研究证实，大多数游泳运动员在整个训练过程中SD的发生率会增加。主要原因可能是稳定肩胛骨的肌肉疲劳，因此，在检查运动员肩部时，在训练后或在临床模拟训练过程后检查SD很重要。
