What is the agonist for flexion at the shoulder?
Agonist is deltoid, antagonist is the latissimus dorsi. As the muscles contract across the shoulder joint it brings your shoulder upward into flexion as you push the ball the opposite happens and the antagonist becomes your deltoid and the latissimus dorsi becomes your agonist.
What are the agonists of the shoulder?
agonistic: anterior deltoid, middle deltoid, teres minor, infraspinatus, levator scapulae, rhomboid major, rhomboid minor, supraspinatus, upper trapezius, middle trapezius, serratus anterior, teres major.
What muscles are used in shoulder flexion?
The muscles involved in the flexion movement include the anterior deltoid, pectoralis major and coracobrachialis. For a shoulder extension, your body uses the latissimus dorsi, teres major and minor and posterior deltoid muscles.
Which muscle is the antagonist to flexion of the arm at the shoulder?
Pectoralis major and latissimus dorsi act as antagonists. The middle region of the deltoid muscle is the prime mover for arm abduction.

What is the agonist for shoulder elevation?
The agonist muscle of the GHJ for the external rotation was set as the infraspinatus. The middle trapezius was defined as the agonist muscles of the STJ since scapular external rotation and retraction was achieved by shoulder external rotation.
What is the agonist in a movement?
Agonist muscles are those we typically associate with movement itself, and are thus sometimes referred to as prime movers. Agonist muscles produce the primary movement or series of movements through their own contractions.
What is the name of the antagonist for arm flexion?
When we flex the elbow, the biceps is the agonist because is causes the elbow to flex. The triceps is the antagonist because it is on the opposite side of the elbow joint and has the potential to oppose the elbow flexion.
What is the antagonist for shoulder abduction?
The opposite, or antagonistic, action of bringing your arm toward the side of your body is called adduction. The adductor muscles are the antagonists of the abductors and include the latissimus dorsi, the pectoralis major and the teres major, along with several accessory muscles.
What muscle is considered an agonist during shoulder external rotation?
The middle trapezius
The middle trapezius was defined as the agonist muscles of the STJ since scapular external rotation and retraction was achieved by shoulder external rotation.

What is the agonist muscle in shoulder external rotation?
The middle trapezius was defined as the agonist muscles of the STJ since scapular external rotation and retraction was achieved by shoulder external rotation.
What is the agonist muscle in a overhead extension?
The triceps are considered the agonist muscle group when you perform exercises specifically for this muscle group, such as overhead arm extensions.
What is the antagonist of the subscapularis?
Action: The subscapularis assists in securing the head of the humerus into the glenoid fossa. It is the primary muscle for humeral medial rotation and assists with adduction. Synergist: Teres major, Latissimus dorsi, and Pectoralis major. Antagonist: Infraspinatus, Teres minor.
