What is the definition of retraction in physical movement?

Retraction in physical movement specifically refers to the act of pulling a body part backward, with a primary focus on the shoulder blades. When you retract your shoulders, you are bringing them closer together and moving them posteriorly. This motion enhances posture and is essential in various physical activities, as it stabilizes the shoulder girdle and can help prevent injuries.

The other choices indicate different types of movements unrelated to retraction. For example, pulling a body part forward would involve protraction, extending a body part outward refers to abduction, and rotating a limb inward denotes internal rotation. Understanding these definitions is crucial as it allows individuals to accurately describe and perform movements involved in sports and rehabilitation.
