Abstract

BackgroundScapular upward rotators are important for the ideal movement pattern of the glenohumeral joint. The Y-raise exercise (YR) can be recommended for the activation of these muscles overall and selectively for the lower trapezius (LT).ObjectiveThis study investigated and compared the activity of scapular upward rotators and activity ratios among three different Y-raise exercises (YR1, YR2, and YR3).MethodsFifteen healthy male individuals participated. All participants performed three different Y-raise exercises in random order: YR1, YR2, and YR3. Muscle activity of the upper trapezius (UT), LT, and serratus anterior (SA) was measured during each exercise using surface electromyography. Comparisons were analyzed by one-way repeated measures ANOVA, followed by Bonferroni adjustment.ResultsUT activity decreased in YR2 (23.21%) compared to YR1 (46.54%) and YR3 (42.95%) (p = 0.001). LT activity increased in YR3 (58.32%) compared to YR1 (46.44%) and YR2 (47.96%) (p = 0.001). The LT/UT activity ratio was higher in YR2 (2.57) compared to YR1 (1.14) and YR3 (1.74) (p = 0.001).ConclusionYR2 and YR3 can be recommended for selective LT activation in early-stage rehabilitation and overall scapular upward rotator activity in late-stage rehabilitation, respectively.

三种不同的y型抬高运动对健康男性肩胛骨上旋活动的影响。

背景：肩胛骨向上旋转体对于肩关节的理想运动模式很重要。y型抬高运动（YR）可以被推荐用于全面激活这些肌肉，并选择性地激活下斜方肌（LT）。目的研究并比较三种不同的YR1、YR2和YR3 Y-raise运动中肩胛骨上旋肌的活动和活动比。方法15名健康男性参与研究。所有参与者按随机顺序进行三种不同的y型抬高练习：YR1， YR2和YR3。在每次运动中使用表面肌电图测量上斜方肌（UT）， LT和前锯肌（SA）的肌肉活动。比较采用单因素重复测量方差分析，然后进行Bonferroni调整。结果YR1（46.54%）和YR3（42.95%）相比，YR2（23.21%）的t活性降低（p = 0.001）。与YR1（46.44%）和YR2（47.96%）相比，YR3（58.32%）的LT活性增加（p = 0.001）。LT/UT活性比YR2（2.57）高于YR1（1.14）和YR3 (1.74) （p = 0.001）。结论yr2和YR3分别可用于早期选择性LT激活和晚期选择性肩胛骨上旋活动。

期刊介绍： The Journal of Back and Musculoskeletal Rehabilitation is a journal whose main focus is to present relevant information about the interdisciplinary approach to musculoskeletal rehabilitation for clinicians who treat patients with back and musculoskeletal pain complaints. It will provide readers with both 1) a general fund of knowledge on the assessment and management of specific problems and 2) new information considered to be state-of-the-art in the field. The intended audience is multidisciplinary as well as multi-specialty. In each issue clinicians can find information which they can use in their patient setting the very next day.
