Domain 1: Anatomy & Physiology (20 Questions)
Q1: A 35-year-old male client is performing a barbell back squat. During the eccentric
phase (lowering), which muscle action is occurring in the quadriceps?
A. Concentric contraction
B. Eccentric contraction. [CORRECT]
C. Isometric contraction
D. Isokinetic contraction
Correct Answer: B
Rationale: During the eccentric phase of a squat (lowering the body), the quadriceps are
lengthening while under tension to control the descent against gravity. This is the
definition of an eccentric contraction—muscle lengthening while generating force.
Option A (concentric) occurs during the ascent when the muscle shortens. Option C
(isometric) involves no change in muscle length (e.g., holding a position). Option D
(isokinetic) requires specialized equipment that maintains constant velocity, not
applicable to free-weight squats. Understanding muscle contraction types is
fundamental for exercise prescription and injury prevention in the ISSA CPT framework.
Q2: Which plane of motion divides the body into anterior and posterior portions, and
includes movements such as lateral raises and side lunges?
A. Sagittal plane
B. Frontal (coronal) plane. [CORRECT]
,C. Transverse plane
D. Horizontal plane
Correct Answer: B
Rationale: The frontal (coronal) plane divides the body into front (anterior) and back
(posterior) portions. Movements in this plane include abduction and adduction—lateral
raises (shoulder abduction) and side lunges (hip abduction/adduction) are classic
examples. Option A (sagittal) divides left/right and includes flexion/extension (squats,
bicep curls). Option C/D (transverse/horizontal) divides upper/lower and includes
rotation (wood chops, Russian twists). ISSA emphasizes understanding planes of
motion for functional movement screening and exercise selection.
Q3: During intense exercise lasting 10-30 seconds (e.g., 100m sprint), which energy
system provides the majority of ATP?
A. Oxidative phosphorylation
B. Glycolysis
C. ATP-PCr (phosphagen) system. [CORRECT]
D. Beta-oxidation
Correct Answer: C
Rationale: The ATP-PCr (phosphagen) system dominates during maximal efforts lasting
0-30 seconds. It provides immediate energy through stored ATP and phosphocreatine
breakdown without oxygen. Option A (oxidative phosphorylation) dominates activities
>2 minutes. Option B (glycolysis) becomes primary between 30 seconds and 2 minutes.
Option D (beta-oxidation) is fat metabolism for prolonged aerobic activity. ISSA CPTs
must understand energy system interplay for conditioning program design and
sport-specific training.
,Q4: Which muscle is the primary agonist for knee flexion?
A. Quadriceps femoris
B. Hamstring group. [CORRECT]
C. Gluteus maximus
D. Gastrocnemius
Correct Answer: B
Rationale: The hamstring group (biceps femoris, semitendinosus, semimembranosus)
is the primary agonist for knee flexion. They originate on the ischial tuberosity and
insert on the tibia/fibula, crossing the posterior knee joint. Option A (quadriceps) is the
antagonist for knee extension. Option C (gluteus maximus) primarily extends the hip.
Option D (gastrocnemius) assists weakly in knee flexion but primarily plantarflexes the
ankle. Understanding agonist-antagonist relationships is essential for balanced
program design and preventing muscle imbalances per ISSA guidelines.
Q5: The "rotator cuff" consists of four muscles that stabilize the glenohumeral joint.
Which muscle is NOT part of this group?
A. Supraspinatus
B. Infraspinatus
C. Teres minor
D. Teres major. [CORRECT]
Correct Answer: D
Rationale: The rotator cuff comprises: SITS - Supraspinatus, Infraspinatus, Teres minor,
and Subscapularis. Teres major (Option D) is not a rotator cuff muscle; it adducts and
medially rotates the humerus but does not primarily stabilize the glenohumeral joint.
The rotator cuff muscles create compressive force holding the humeral head in the
, glenoid fossa during arm movement. Knowledge of shoulder anatomy is critical for ISSA
CPTs to prevent impingement and design appropriate upper body programs.
Q6: Which type of bone is light, porous, and found at the ends of long bones?
A. Compact bone
B. Cancellous (spongy) bone. [CORRECT]
C. Fibrous bone
D. Lamellar bone
Correct Answer: B
Rationale: Cancellous (spongy/trabecular) bone is porous, lightweight, and located at
epiphyses (ends) of long bones and within vertebrae. Its trabecular structure provides
strength along stress lines while remaining lightweight. Option A (compact/cortical
bone) is dense and forms the diaphysis (shaft). Option C (fibrous bone) is immature,
temporary bone in fetal development and fracture repair. Option D (lamellar bone) refers
to the layered organization of mature bone, both compact and cancellous.
Understanding bone structure helps ISSA CPTs address osteoporosis programming and
impact exercise safety.
Q7: During cardiovascular exercise, which chamber of the heart pumps oxygenated
blood to the systemic circulation?
A. Right atrium
B. Right ventricle
C. Left atrium
D. Left ventricle. [CORRECT]
Correct Answer: D
