CPCS EXAM 318 ACTUAL TEST 2026
QUESTIONS WITH VERIFIED ANSWERS
◉ What are length-tension relationships? Answer: The length at
which maximum power occurs for a contraction
◉ What is a force couple? Answer: muscles pulling in different
directions to accomplish the same motion
◉ What is an agonist muscle? Answer: Prime mover
◉ What is an antagonist muscle? Answer: The muscle that does the
opposite of the agonist
◉ What is a synergist muscle? Answer: A muscle that assists agonist
◉ What is a stabilizer muscle? Answer: A muscle that stabilizes the
joint during movement
◉ What is a concentric contraction? Answer: Shortening of muscle
◉ What is eccentric contraction? Answer: Lengthening of a muscle
,◉ What is isometric contraction? Answer: Tension on a muscle with
no shortening or lengthening
◉ What is the ground reaction force while walking? Answer: 1.5
◉ What is the ground reaction force while jogging? Answer: 5x
◉ What is the ground reaction force while jumping? Answer: 10x
◉ What attributes do local systems have? Answer: Deep, smaller,
and close to joint (usually stabilizers)
◉ What is a first class lever? Answer: Fulcrum in the middle
◉ What is an example of a first class lever in the body? Answer:
Atlanto occipital joint
◉ What is a second class lever? Answer: A lever with the load in the
middle
◉ An example of a second class lever in the human body? Answer:
Calf raises
, (Toe is F
Heel is L
Gastroc is E)
◉ What attributes do global systems have? Answer: Bigger,
superficial, involved in movement (transfer or absorb shock)
◉ Which tissues make up the Deep Longitudinal Subsystem (DLS)?
Answer: Erector spinae, Thoracolumbar fascia, Sacrotubule
Ligament, Biceps Femoris, and Peronious Longus
◉ What is the DLS role? Answer: To transfer force from the ground
to the trunk back to the ground (control ground reaction forces)
Stabilize the SIJ
◉ What does the Posterior Oblique Subsystem (POS) consist of?
Answer: Glute max, Thoracolumbar ligament, and Latissimus dorsi
◉ What role does the POS play? Answer: Provide transverse support
to the SIJ
◉ How does the POS provide transverse support? Answer: Its fibers
run perpendicular to the joint
