Strength improvement of the shoulder muscles is a major goal in rehabilitation or athletic conditioning programs. The purpose of this study was to determine the effect of shoulder core exercises on the isometric torque of glenohumeral joint movements.
A total of 36 healthy females with no history of shoulder injury enrolled in this study. Subjects were randomly assigned into the control group (n = 18, 22 ± 2.19 years of age) or experimental group (n = 18, 21 ± 2.05 years of age). Subjects in experimental group performed shoulder core exercises, using progressive resistance training, three times a week for six weeks. Subjects in control group performed no exercise. The isometric torque of shoulder movements were measured with Dynatorq device in isolated test positions of glenohumeral muscles at the beginning and after six weeks in both groups.
shoulder core exercise training led to an increase in maximal isometric torques of shoulder scaption at 0° and 90° arm elevation, external and internal rotation, horizontal adduction and extension movements (p < 0.001 in all instances). No significant difference was found between initial scores and scores after six weeks in the control group (p > 0.05).
These findings indicated that shoulder core exercise training leads to an increase in peak torque for all glenohumeral movements that can be considered in glenohumeral muscles strengthening programs.
肩部肌肉力量的增强是康复或运动训练计划的主要目标。本研究的目的是确定肩部核心练习对盂肱关节运动等长扭矩的影响。
共有36名无肩部损伤史的健康女性参与本研究。受试者被随机分为对照组（n = 18，年龄22±2.19岁）或实验组（n = 18，年龄21±2.05岁）。实验组受试者采用渐进性抗阻训练进行肩部核心练习，每周三次，共六周。对照组受试者不进行任何运动。两组在实验开始时及六周后，使用Dynatorq设备在盂肱肌肉的孤立测试位置测量肩部运动的等长扭矩。
肩部核心练习训练导致在手臂抬高0°和90°时肩部外展、外旋和内旋、水平内收和伸展运动的最大等长扭矩增加（在所有情况下p < 0.001）。对照组初始分数与六周后的分数之间未发现显著差异（p > 0.05）。
这些结果表明，肩部核心练习训练会导致所有盂肱关节运动的峰值扭矩增加，这在盂肱肌肉强化计划中是可以考虑的。
