Question

When a person does a push up, first pushing off the floor and fully straightening their elbow and then returning to the ground so that their chest touches the floor, what motions does the scapula go through

A) Protraction and then retraction

B) Retraction and then protraction

C) Adduction and then abduction

D) Flexion and circumduction

Answer 1

Answer:- A) Protraction and then retraction

Explanation:- When a person does a push-up, during the initial phase of pushing off the floor and fully straightening their elbow, scapula moves laterally away from the spinal column. This movement of the joint is known as protraction (scapular abduction). Then during push up secondary (lowering) phase, scapula moves medially toward the spinal column. This movement of the joint is known as retraction (scapular adduction). Thus, the scapula go through motion of protraction and then retraction.
