Which term refers to the movement of the shoulder blade during arm abduction?

The movement of the shoulder blade during arm abduction is best described by the concept of scapulohumeral rhythm. This term refers to the coordinated movement between the scapula and the humerus that occurs as the arm is raised. Specifically, during arm abduction, as the humerus moves upward, the scapula rotates and tilts slightly to allow for optimal movement and function of the shoulder joint.

Scapulohumeral rhythm ensures that there is an appropriate relationship between shoulder joint movement and scapular motion, helping to preserve joint stability and prevent injury. This synergy between the two structures is crucial for efficient arm elevation and overall shoulder function. Understanding this rhythm helps to appreciate how the body performs complex movements and the anatomical relationships involved in strength and conditioning training.
