The trapezius abducts the arm from 90 degrees to 160 degrees (90-160 degrees) (Penn State), or also just greater than >90 degrees (USMLE First Aid) (Lam et al 2019). Agonist muscles are the muscles that perform a movement, while antagonist muscles perform the opposite movements. For example; weakness with the serratus anterior and lower trapezius muscle, and/or an over activation of the upper trapezius muscle, scapular downward rotators overactivity for a long time all affect the scapula upward rotation and you can find scapula on anterior tipping. A muscle that crosses the anterior side of a joint results in flexion, which results in a decrease in joint angle with movement. However, because of the vast range of motion of the shoulder complex (the most mobile joint of the human body), dynamic stabilizers are crucial for a strong sense of neuromuscular control throughout all movements and activities involving the upper extremities. antagonist: gluteus minimus, hamstrings deltoid The deltoid can abduct the shoulder arm from 15 degrees to 90 degrees (15-90 degrees). The primary agonist muscles used during a shoulder press are the anterior deltoids and the triceps brachii, while the primary antagonist muscles are the latissimus dorsi and the biceps brachii. During shoulder extension or when returning your arm beside your body, this movement is associated with scapular downward rotation, internal rotation, and shoulder depression. White Lion Athletics.
