Skulderabduksjon

Skulderabduksjon, also known as shoulder abduction, is a movement that involves lifting the arm away from the body in the frontal plane. This action is initiated by the deltoid muscle, specifically the anterior fibers, which originate from the lateral aspect of the clavicle and insert on the greater tubercle of the humerus. The deltoid muscle is a large, triangular muscle that covers the shoulder joint and is responsible for various movements of the arm, including abduction, flexion, and extension.

Shoulder abduction is a crucial movement for daily activities such as reaching for objects, lifting the arm to brush hair, and performing overhead exercises. It is also an essential component of many sports and physical activities, including swimming, tennis, and weightlifting. Proper shoulder abduction is necessary for maintaining a healthy range of motion and preventing injuries to the shoulder joint.

However, excessive or improper shoulder abduction can lead to various musculoskeletal issues, such as rotator cuff tendinitis, impingement syndrome, and shoulder pain. These conditions can be caused by repetitive overhead movements, poor posture, or weakness in the shoulder muscles. To maintain optimal shoulder health, it is important to perform regular exercises that target the muscles involved in shoulder abduction, such as overhead presses and lateral raises, and to maintain a balanced and active lifestyle.
