Domain 1: Anatomy & Kinesiology (12 Questions)
Q1: During a step aerobics class, a participant performs a basic step-up movement
where the right foot steps up onto the platform followed by the left foot, then both step
down. When analyzing the right hip joint during the initial step-up phase, which joint
action is occurring?
A. Hip extension
B. Hip adduction
C. Hip flexion [CORRECT]
D. Hip external rotation
Correct Answer: C
,Rationale: During the step-up phase, the femur moves anteriorly toward the trunk in the
sagittal plane, which is defined as hip flexion. The rectus femoris, iliopsoas, and
sartorius are the primary hip flexors concentrically contracting to lift the thigh.
Why A is incorrect: Hip extension would occur if the thigh were moving posteriorly away
from the trunk, such as during the push-off phase or when stepping backward.
Why B is incorrect: Hip adduction occurs in the frontal plane when the femur moves
toward the midline of the body, which does not happen during a standard forward
step-up.
Why D is incorrect: Hip external rotation occurs in the transverse plane when the femur
rotates outward, which is not a component of a basic step-up movement.
Q2: In a strength training segment of a group exercise class, participants are performing
dumbbell lateral raises. Which muscle group is the primary mover (agonist) during the
concentric phase of this movement?
A. Pectoralis major
B. Deltoids (middle fibers) [CORRECT]
C. Latissimus dorsi
D. Trapezius (upper fibers)
,Correct Answer: B
Rationale: The dumbbell lateral raise is a frontal plane movement involving shoulder
abduction. The middle fibers of the deltoid are the primary agonist responsible for
abducting the humerus from 0-90 degrees. The supraspinatus initiates the first 15
degrees of abduction, but the middle deltoid completes the majority of the movement.
Why A is incorrect: The pectoralis major is primarily responsible for shoulder adduction,
flexion, and horizontal adduction—not abduction. It acts as an antagonist during lateral
raises.
Why C is incorrect: The latissimus dorsi is a powerful shoulder adductor, extensor, and
internal rotator. It performs the opposite action of abduction and acts as an antagonist
during lateral raises.
Why D is incorrect: While the upper trapezius assists with upward rotation of the scapula
during abduction beyond 90 degrees, it is not the primary mover for the arm movement
itself. The primary action occurs at the glenohumeral joint, not the scapulothoracic
articulation.
Q3: A group exercise instructor is teaching a squat exercise and cues participants to
lower their hips back and down. Which joint action occurs at the knee during the
eccentric (lowering) phase of the squat?
A. Knee extension
, B. Knee flexion [CORRECT]
C. Knee abduction
D. Knee internal rotation
Correct Answer: B
Rationale: During the eccentric phase of a squat, the tibia moves posteriorly relative to
the femur, resulting in knee flexion. The quadriceps group (rectus femoris, vastus
lateralis, vastus medialis, vastus intermedius) lengthens under tension to control the
descent, demonstrating eccentric muscle action. The knee flexes to approximately
90-110 degrees in a standard squat.
Why A is incorrect: Knee extension occurs during the concentric (rising) phase of the
squat when the quadriceps shorten to straighten the leg. This is the opposite action of
the lowering phase.
Why C is incorrect: Knee abduction is not a normal physiological movement at the
tibiofemoral joint. The knee is a modified hinge joint primarily capable of flexion and
extension with minimal rotation when flexed.
Why D is incorrect: While some internal and external rotation occurs at the knee when it
is flexed beyond 90 degrees (the "screw-home mechanism" occurs in extension),
internal rotation is not the primary joint action during a standard squat descent.
