Question

The chest musculature is the prime mover for most upper body pushing exercises, whereas the __ brachii and anterior __ act as synergists throughout the movement pattern.

A.Biceps, Deltoid
B.Triceps, Latissimus Dorsi
C.Brachialis, Rhomboids
D.Triceps, Pectoralis Major

Answer 1

In upper body pushing exercises, the triceps brachii and pectoralis major act as synergists, assisting the chest musculature which is the prime mover; therefore, the correct answer is D. Triceps, Pectoralis Major.

Step-by-step explanation:

The chest musculature is the prime mover for most upper body pushing exercises, whereas the triceps brachii and anterior pectoralis major act as synergists throughout the movement pattern. The correct answer to the student's question is D. Triceps, Pectoralis Major. The triceps are responsible for extending the elbow, which assists in the pushing motion, and the pectoralis major helps stabilize and add force to the push. Although other muscles such as the biceps brachii, brachialis, and deltoid also play roles in upper limb movements, for the specific context of pushing movements, the triceps brachii and pectoralis major are the relevant synergists.
