The aim of our study was to investigate the relation of workload on range of motion and isometric strength of team handball athletes' shoulders over a competitive season.
31 Professional male handball athletes underwent clinical shoulder examinations. Athletes were examined subsequently during the complete playing season (week 0, 6, 22 and 40) to determine bilateral isometric shoulder rotational strength and active range of motion (ROM). In addition, relative (intraclass correlation coefficients (ICC) and absolute (standard error of measurement) reliability were calculated.
Intraobserver reliability was excellent (ICC 0.76-0.98) for isometric strength and flexibility measurements. Internal rotation (IR) and total arc ROM in the throwing shoulder (TS) decreased significantly (p < 0.05) in both sequences (week 22 to week 40, week 0 to week 40). External rotation (ER) ROM and isometric strength in IR and ER did not change significantly. Glenohumeral internal rotation deficit (GIRD) and external rotation gain (ERG) of the TS decreased significantly between week 22 and week 40, but both did not change overall (week 0 to week 40). There was significant influence on IR ROM (week 22 to week 40) and strength in ER (week 0 to week 40) in the non-throwing shoulder.
Several characteristics of handball players' shoulders changed significantly from the beginning to the end of a season. More specifically, the repetitive forces accumulated during the competitive season resulted in altered GIRD, ERG and isometric strength of the dominant glenohumeral joint.
我们研究的目的是调查在一个竞技赛季中，团队手球运动员肩部的工作量与活动范围和等长力量之间的关系。
31名职业男性手球运动员接受了肩部临床检查。在整个比赛赛季（第0周、第6周、第22周和第40周）对运动员进行后续检查，以确定双侧肩部等长旋转力量和主动活动范围（ROM）。此外，还计算了相对（组内相关系数（ICC））和绝对（测量标准误差）可靠性。
等长力量和柔韧性测量的观察者内可靠性极佳（ICC为0.76 - 0.98）。在两个时间段（第22周至第40周、第0周至第40周），投掷肩（TS）的内旋（IR）和总弧ROM均显著降低（p < 0.05）。外旋（ER）ROM以及IR和ER中的等长力量没有显著变化。TS的盂肱关节内旋不足（GIRD）和外旋增加（ERG）在第22周和第40周之间显著降低，但总体上两者均未改变（第0周至第40周）。非投掷肩的IR ROM（第22周至第40周）和ER力量（第0周至第40周）受到显著影响。
从赛季开始到结束，手球运动员肩部的几个特征发生了显著变化。更具体地说，竞技赛季中积累的重复力量导致优势盂肱关节的GIRD、ERG和等长力量发生改变。
