What is a common movement of the shoulder during a throwing motion?

During a throwing motion, the shoulder typically undergoes internal rotation as the arm moves forward to release the object, such as a ball. This internal rotation helps position the shoulder to generate the maximum force and speed necessary for an effective throw.

The biomechanics involved during the throwing phase require the shoulder to rotate internally while the body follows through with the movement. This plays a crucial role in the coordination and power of the throw. Maximal internal rotation also aids in stabilizing the shoulder, ensuring that it can withstand the forces generated throughout the throwing action.

While other movements involving flexion, extension, and external rotation can occur at various points in the throwing motion, they do not characterize the primary action of the shoulder during the critical moment of release. Internal rotation is essential for achieving the optimal throwing mechanics and delivering the object with precision.
