What is the agonist for abduction of the arm?
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. Gives you the force to push the ball.

What is abduction of the arm?
In general terms, abduction in the anatomical sense is classified as the motion of a limb or appendage away from the midline of the body. In the case of arm abduction, it is the movement of the arms away from the body within the plane of the torso (sagittal plane).
What is the prime mover of arm abduction?
The middle region of the deltoid muscle is the prime mover for arm abduction. The pectoralis major acts as an antagonist to the middle deltoid anteriorly, whilst the latissimus dorsi acts as the antagonist posteriorly.
What is a shoulder abduction?
Shoulder abduction Abduction occurs when you have arm movement away from the middle of your body. When you raise your arm out from the sides of your body, it’s an abduction of your shoulder. A normal range for abduction, starting with your palms at your sides, is around 150 degrees in a healthy shoulder.
What is adduction of the arm?
Arm adduction represents movement of the arm towards the midline of the body in the coronal plane. Most individuals can manage 40° of isolated adduction. It is the opposite of arm abduction and contributes to the combined movement of shoulder circumduction. It is produced by: pectoralis major (sternal part)
What muscle causes abduction of the arm?
The supraspinatus muscle originates from the supraspinous fossa of the scapula, passes under the acromion, and inserts on the superior facet of the greater tubercle of the humerus. It is responsible for the initiation of arm abduction and is in control of the motion up to the first 15 degrees of abduction.
What is arm abduction?
In the case of arm abduction, it is the movement of the arms away from the body within the plane of the torso (sagittal plane).
What is shoulder abduction in gymnastics?

What is the difference between shoulder adduction and finger abduction?
During arm abduction (also called shoulder abduction), the arms move away from the body’s midline. During arm adduction (or shoulder adduction), you ADD them right back toward the midline. Finger Abduction and Adduction
What muscle abducts the upper arm?
The deltoid muscle abducts the arm, but at 90 degrees the humerus bumps into the acromion. People also ask, what muscles are used in abduction of the shoulder? In summary, the muscles that stabilize the shoulder include the trapezius, the rhomboids, the levator scapulae, serratus anterior and pectoralis minor.
