What Muscles Are Used When Throwing A Baseball?
The answer to this question is not as simple as it may seem. There are several muscles used when throwing a baseball, and the specific ones used may depend on the type of throw being made.
Anterior Deltoid
The anterior deltoid is the largest and strongest part of the deltoid muscle. It is located in the front part of the shoulder. The anterior deltoid helps to raise the arm away from the body. It is used when throwing a baseball.
Pectoralis Major
The pectoralis major is a large, fan-shaped muscle that covers the front of your chest. It attaches to the breastbone (sternum) and ribs in the front, and it inserts on the inside edge of your upper arm bone (humerus). The pectoralis major is responsible for several shoulder and arm movements, including:
– Flexing your shoulder (bringing your arm forward and up)
– Adducting your shoulder (bringing your arm toward your body)
– Internally rotating your shoulder (turning your arm inward)
As one of the most powerful muscles in your upper body, the pectoralis major also plays an important role in stabilizing your shoulder joint.
Latissimus Dorsi
The latissimus dorsi is the largest muscle in the upper body. It is located in the middle back and extends from the lower back to the upper arm. The latissimus dorsi is responsible for internal rotation of the arm, extension of the arm, and adduction of the arm. This muscle is also responsible for stabilizing the shoulder joint.
Triceps Brachii
The triceps brachii, often just called the triceps, is a large muscle on the back of the upper arm. It has three parts, all of which Insertion: olecranon process of ulna (2), long head: infraglenoid tubercle of scapula Action: extension of elbow, long head also extends and adducts shoulder.
External Obliques
The external obliques are located on the sides of the abdomen and attach to the lower ribs. These muscles work together with the internal obliques to provide rotational force when throwing a baseball.
