What muscles are prone to injury because they have less support from larger and required for deceleration of the arm during any throwing or swinging movements?

Answer: The rotator cuff muscles

The rotator cuff muscles are a group of four tendons and muscles that surround the shoulder joint. These muscles help to keep the shoulder joint in place and allow the arm to move in a wide range of motions.

The rotator cuff muscles are prone to injury because they are often overused, especially in overhead athletes. Overuse can cause the tendons to become inflamed or torn, which can lead to pain, weakness, and loss of range of motion.

The rotator cuff muscles are also at risk for injury because they have less support from larger muscles. The larger muscles of the shoulder, such as the deltoid and pectoralis major, help to protect the rotator cuff muscles from injury. However, when these larger muscles are fatigued or injured, the rotator cuff muscles can become more susceptible to injury.

Athletes who participate in overhead sports, such as baseball, tennis, and swimming, are at an increased risk for rotator cuff injuries. However, anyone can suffer a rotator cuff injury, even if they do not participate in sports.

If you experience pain, weakness, or loss of range of motion in your shoulder, it is important to see a doctor to rule out a rotator cuff injury. Early diagnosis and treatment can help to prevent further injury and improve your symptoms.
