Various authors have ascribed differing roles to the adductor muscles of the thigh in producing rotation of the femur. In the present study, measurements have been made on the changes in distance between origin and insertion of the adductor muscles which occur with rotation of the femur. Increases in distance indicate the muscle cannot produce a particular movement, while a decrease in length supports an argument that the muscle has a particular function. Measurements were made for positions of flexion-extension and adduction-abduction as well as anatomical rest. The adductor magnus was found to decrease in length during internal rotation while the adductor longus decreased in length during external rotation in most of the positions studied.
不同作者认为大腿内收肌在股骨旋转过程中发挥着不同作用。在本研究中，已对股骨旋转时内收肌起止点间距离的变化进行了测量。距离增加表明该肌肉无法产生特定运动，而长度减小则支持该肌肉具有特定功能这一观点。针对屈伸、内收外展以及解剖学静止位进行了测量。发现在大多数研究位置中，大收肌在股骨内旋时长度减小，而长收肌在股骨外旋时长度减小。
