摘要

背景：恢复肩胛骨向上旋转肌（上斜方肌（UT）、前锯齿肌（SA）和下斜方骨（LT））之间失衡的运动重点通常是增加SA和LT活性，而不是增加UT活性。目的：本研究的目的是比较肩胛骨向上旋转（SUR）运动和肩胛骨外展运动（两种传统运动）期间UT、SA和LT肌肉的活动。方法：共有29名健康的年轻成年男性进行了三项最大等长收缩的运动。记录UT、SA和LT的肌电图活动。结果：超声心动图表现出最高的活动性。SA活性在延长期最低。然而，在SCAPE和SUR的执行过程中，SA活性没有发现差异。术中SA/UT比值最高。结论：SUR是一种新的运动，可以在中等强度下进行肩部康复，以恢复肩胛骨向上旋转肌失衡。

Comparison of scapular upward rotator muscle activities and activity ratios during three scapular upward rotator strengthening exercises

BACKGROUND: The focus of exercises for restoring the imbalance between scapular upward rotator muscles – upper trapezius (UT), serratus anterior (SA), and lower trapezius (LT) – commonly aims to increase SA and LT activities while not increasing UT activity. OBJECTIVES: The purpose of this study was to compare the activity of the UT, SA, and LT muscles during scapation and protraction exercises, which are two traditional exercises, and during a newly designed scapular upward rotation (SUR) exercise. METHODS: A total of 29 healthy young adult men performed all three exercises with maximum isometric contraction. The electromyographic activities of the UT, SA, and LT were recorded. RESULTS: UT demonstrated the highest activity during scapation. SA activity was the lowest during protraction. However, no difference was found in SA activity during the performance of scapation and SUR. The SA/UT ratio was the highest during scapation. CONCLUSIONS: SUR is a new exercise that can be performed at moderate intensity for shoulder rehabilitation to restore scapular upward rotator muscle imbalance.

期刊介绍： Isokinetics and Exercise Science (IES) is an international journal devoted to the study of theoretical and applied aspects of human muscle performance. Since isokinetic dynamometry constitutes the major tool in this area, the journal takes a particular interest in exploring the considerable potential of this technology. IES publishes studies associated with the methodology of muscle performance especially with respect to the issues of reproducibility and validity of testing, description of normal and pathological mechanical parameters which are derivable from muscle testing, applications in basic research topics such as motor learning paradigms and electromyography. The journal also publishes studies on applications in clinical settings and technical aspects of the various measurement systems employed in human muscle performance research. The journal welcomes submissions in the form of research papers, reviews, case studies and technical reports from professionals in the fields of sports medicine, orthopaedic and neurological rehabilitation and exercise physiology.
