Question 1: What are the three primary interdependent systems that
comprise the human movement system (kinetic chain)?
• A) Cardiovascular, respiratory, and endocrine systems
• B) Skeletal, muscular, and nervous systems
• C) Digestive, lymphatic, and integumentary systems
• D) Hepatic, renal, and nervous systems
Correct Answer: B
Rationale: The human movement system consists of the kinetic chain,
which integrates the skeletal system, muscular system, and nervous
system to produce and control human movement.
Question 2: Which component of the nervous system is responsible for
sensing tension, position, and movement changes via
mechanoreceptors?
• A) Central nervous system (CNS)
• B) Peripheral nervous system (PNS) - sensory (afferent) division
• C) Autonomic sympathetic division
• D) Endocrine feedback loop
Correct Answer: B
,Rationale: The peripheral nervous system's sensory (afferent) division
gathers information from mechanoreceptors (like muscle spindles and
Golgi tendon organs) and transmits it to the central nervous system.
Question 3: During an Overhead Squat Assessment, an athlete's feet
turn out. Which of the following muscles are typically considered
overactive or tight?
• A) Anterior tibialis and posterior tibialis
• B) Lateral gastrocnemius, soleus, and short head of the biceps
femoris
• C) Gluteus medius and gluteus maximus
• D) Vastus medialis oblique (VMO)
Correct Answer: B
Rationale: Feet turning out during a squat is commonly caused by
overactive/tight lateral calf muscles (lateral gastrocnemius, soleus) and
the biceps femoris short head, coupled with underactive medial soft
tissues.
Question 4: What is the primary neuromuscular phenomenon that
occurs during autogenic inhibition via foam rolling or static stretching?
• A) Excitation of the antagonist muscle causing muscle tearing
• B) Stimulation of Golgi tendon organs leading to relaxation of the
target muscle
• C) Rapid contraction of muscle spindles causing high tension
• D) Complete shutdown of the cardiovascular system
Correct Answer: B
,Rationale: Autogenic inhibition occurs when tension on a tendon
stimulates Golgi tendon organs (GTOs), overriding muscle spindles and
causing the motor neuron to relax the muscle.
Question 5: Which postural distortion pattern is characterized by foot
pronation (flat feet), knee valgus, and adducted/internally rotated hips?
• A) Upper crossed syndrome
• B) Lower crossed syndrome
• C) Pronation distortion syndrome
• D) Kyphotic-lordotic syndrome
Correct Answer: C
Rationale: Pronation distortion syndrome involves joint dysfunction
characterized by foot pronation, knee flexion/valgus, and internal
rotation of the femur, leading to altered lower extremity mechanics.
Question 6: In Lower Crossed Syndrome, which muscle group is typically
tight and overactive?
• A) Gluteus maximus and hamstrings
• B) Hip flexors and lumbar erector spinae
• C) Transverse abdominis and internal obliques
• D) Anterior tibialis and peroneals
Correct Answer: B
Rationale: Lower crossed syndrome features anterior pelvic tilt driven
by overactive/tight hip flexors (e.g., psoas, rectus femoris) and lower
back extensors (erector spinae).
, Question 7: What is the primary function of the local stabilization
system of the core?
• A) Producing high-velocity rotational power for throwing
• B) Providing intersegmental stability and stiffness to individual
vertebrae of the spine
• C) Pumping blood directly to the working skeletal muscles
• D) Driving maximal sprinting velocity
Correct Answer: B
Rationale: Local core stabilizers (such as the transverse abdominis,
multifidus, and internal obliques) attach directly to the vertebrae to
provide local intersegmental stability and spinal stiffness.
Question 8: Which energy system is dominant during a high-intensity
explosive movement lasting between 10 and 50 seconds (e.g., a 400-
meter sprint)?
• A) ATP-PC (Phosphagen) system
• B) Anaerobic glycolysis (glycolytic system)
• C) Oxidative (aerobic) system
• D) Beta-oxidation pathway
Correct Answer: B
Rationale: Anaerobic glycolysis provides the primary energy source for
high-intensity efforts lasting roughly 10 seconds to 2 minutes by
breaking down glucose without oxygen.
