UNIT 1: EXERCISE SCIENCES (Questions 1-30)
Q1 [AO1 - Knowledge]: The sartorius muscle originates at the anterior superior
iliac spine (ASIS) and inserts at the medial aspect of the tibia. What are its
primary actions?
A. Hip extension and knee flexion
B. Hip flexion, abduction, and external rotation; knee flexion [CORRECT]
C. Hip adduction and knee extension
D. Hip extension and knee internal rotation
Correct Answer: B
Rationale: The sartorius is the longest muscle in the body and crosses both the hip and knee
joints. Its path from ASIS to medial tibia creates a unique diagonal pull that produces hip
flexion, abduction, and external rotation, plus knee flexion. This combination allows the
"tailor's position" (cross-legged sitting). Distractor A confuses it with the hamstrings at the
hip. Distractor C describes the adductor group. Distractor D reverses the rotation component.
Q2 [AO1 - Knowledge]: Which plane of motion divides the body into anterior and
posterior portions?
A. Sagittal plane
B. Frontal (Coronal) plane [CORRECT]
C. Transverse plane
D. Horizontal plane
Correct Answer: B
,Rationale: The frontal (coronal) plane runs vertically from side to side, dividing the body into
front (anterior) and back (posterior) sections. Movements in this plane include
abduction/adduction and lateral flexion. The sagittal plane (A) divides left/right. The
transverse plane (C) divides upper/lower. D (Horizontal) is synonymous with transverse,
making it a duplicate incorrect option.
Q3 [AO2 - Application]: A client performing a lateral dumbbell raise is working
primarily in which plane of motion, and what type of lever is the shoulder acting
as during this movement?
A. Sagittal plane; first-class lever
B. Frontal plane; third-class lever [CORRECT]
C. Transverse plane; second-class lever
D. Frontal plane; first-class lever
Correct Answer: B
Rationale: Lateral raises occur in the frontal plane (abduction away from the body's midline).
The shoulder acts as a third-class lever where the effort (deltoid contraction) is applied
between the fulcrum (glenohumeral joint) and the resistance (dumbbell in hand). This is the
most common lever type in the human body for limb movement. Distractor D correctly
identifies the plane but incorrectly identifies the lever class.
Q4 [AO1 - Knowledge]: During the eccentric phase of a bench press, which
muscle group is undergoing an isotonic contraction while lengthening?
A. Pectoralis major and anterior deltoid [CORRECT]
B. Triceps brachii
C. Latissimus dorsi
D. Biceps brachii
Correct Answer: A
Rationale: During the lowering (eccentric) phase of bench press, the pectoralis major and
anterior deltoid lengthen under tension to control the descent of the bar. While the triceps (B)
also lengthen, they are not the primary movers. The pectoralis is the prime mover being
,stretched. Distractor C (latissimus) is not significantly involved in horizontal pressing.
Distractor D (biceps) acts as a stabilizer but not a primary lengthening mover.
Q5 [AO1 - Knowledge]: During the concentric phase of a biceps curl, the prime
mover is the biceps brachii. What is the primary role of the triceps brachii in this
movement?
A. Agonist
B. Antagonist [CORRECT]
C. Synergist
D. Stabilizer
Correct Answer: B
Rationale: The antagonist muscle performs the opposite action of the prime mover (agonist).
During elbow flexion (biceps curl), the triceps brachii (elbow extensor) must relax and
lengthen to allow the movement, acting as the antagonist. It provides coordinated reciprocal
inhibition. Distractor A confuses the roles. Distractor C (synergist) would be the brachialis or
brachioradialis assisting the biceps.
Q6 [AO2 - Application]: A client is performing a plank exercise. What is the
primary muscle contraction type occurring in the rectus abdominis?
A. Concentric
B. Eccentric
C. Isometric [CORRECT]
D. Isokinetic
Correct Answer: C
Rationale: In a plank, the rectus abdominis contracts to maintain spinal neutral alignment
against gravity without changing length—this is an isometric contraction. There is no joint
movement creating length change. Distractors A and B require movement
(shortening/lengthening). Distractor D requires specialized equipment that maintains
constant velocity.
, Q7 [AO1 - Knowledge]: Which energy system provides ATP for a maximal effort
vertical jump test?
A. Oxidative (Aerobic) system
B. Glycolytic (Lactic Acid) system
C. ATP-PCr (Phosphagen) system [CORRECT]
D. Beta-oxidation system
Correct Answer: C
Rationale: The ATP-PCr (phosphagen) system provides immediate energy for high-intensity
activities lasting approximately 0-10 seconds, such as a single maximal jump. It requires no
oxygen and produces no lactate. Distractor B supports 30 seconds to 2 minutes of intense
activity. Distractor A supports prolonged moderate activity. Distractor D is a metabolic
process for fat utilization, not an energy system.
Q8 [AO3 - Analysis]: A sprinter is competing in the 100-meter dash. Which
statement BEST describes the energy system interplay during this event?
A. Exclusive use of the ATP-PCr system for the entire duration
B. Predominantly ATP-PCr with increasing contribution from the glycolytic system in the final
20-30 meters [CORRECT]
C. Equal contribution from all three energy systems throughout
D. Primarily oxidative phosphorylation with anaerobic assistance
Correct Answer: B
Rationale: The 100m dash (9-10 seconds for elite, 12-15 seconds for recreational) begins with
near-exclusive ATP-PCr system use. However, as PCr stores deplete (approximately 50% by
10 seconds), the glycolytic system contributes increasingly to maintain power output,
especially in the final phase. Distractor A ignores the glycolytic contribution in longer 100m
efforts. Distractor C is incorrect as the oxidative system contributes minimally. Distractor D
reverses the primary systems.
Q9 [AO1 - Knowledge]: What is the primary action of the gluteus medius during
the stance phase of gait?
