The aim of the study was to investigate which muscles contract (and to what extent) during diagonal shoulder movements resisted by a weight-and-pulley-circuit and the relationship between the calculated resisting moment of force and the maximum voluntary isometrical muscular moment. EMG, mechanical calculations and measurements of moments of force were used. With the resistance used in the study, flexion-abduction-external rotation (FLABER) highly activated all three parts of the deltoideus muscle and the infraspinatus. Flexion-adduction-external rotation (FLADER) highly activated the anterior and middle parts of the deltoideus, infraspinatus and moderately the sternocostal part of the pectoralis major. Extension-abduction-internal rotation (EXABIR) highly activated the posterior deltoideus and moderately the latissimus dorsi. Extension-adduction-internal rotation (EXADIR) highly activated the sternocostal part of the pectoralis major.
该研究的目的是调查在由重物和滑轮系统提供阻力的肩部对角运动过程中，哪些肌肉会收缩（以及收缩程度如何），并研究计算得出的阻力矩与最大自主等长肌肉力矩之间的关系。研究采用了肌电图（EMG）、力学计算和力矩测量方法。在所使用的阻力条件下，屈曲 - 外展 - 外旋（FLABER）动作高度激活了三角肌的所有三个部分以及冈下肌。屈曲 - 内收 - 外旋（FLADER）动作高度激活了三角肌的前部和中部、冈下肌，同时也适度激活了胸大肌的胸肋部。伸展 - 外展 - 内旋（EXABIR）动作高度激活了三角肌后部，同时也适度激活了背阔肌。伸展 - 内收 - 内旋（EXADIR）动作高度激活了胸大肌的胸肋部。
