Question 1

During the bench press, which muscle group acts as the primary agonist?

Accepted Answer

Pectoralis major, anterior deltoid, and triceps brachii

Answer

The pectoralis major, anterior deltoid, and triceps brachii are the prime movers during the pressing phase of the bench press.

Question 2

Which plane of motion does a lateral shoulder raise primarily occur in?

Accepted Answer

Frontal plane

Answer

A lateral (side) shoulder raise moves the arm away from the body's midline in the frontal (coronal) plane.

Question 3

Ground reaction force (GRF) during a vertical jump is best described as:

Accepted Answer

The equal and opposite force the ground exerts on the athlete

Answer

GRF is Newton's third law in action — the ground exerts a force equal in magnitude and opposite in direction to the force the athlete applies to the ground.

Question 4

The angle of pennation of a muscle fiber refers to:

Accepted Answer

The angle between the muscle fibers and the muscle's line of pull (tendon)

Answer

Pennation angle describes the orientation of muscle fibers relative to the line of pull of the tendon, affecting force production and range of motion.

Question 5

Which axis of rotation is associated with transverse plane movements such as internal and external shoulder rotation?

Accepted Answer

Longitudinal (vertical) axis

Answer

Transverse plane rotations (internal/external rotation, pronation/supination) occur around the longitudinal (vertical) axis of the body.
