NSCA CSCS Exam 2025 | Certified Strength &
Conditioning Specialist Study Guide with 100% Verified
Questions & Answers
1. What is the effect of stimulating muscle spindles during a stretch?
Contraction of the stretched muscle
Relaxation of GTOs
Contraction of the reciprocal muscle
Relaxation of the stretched muscle
2. What is the most widely used method for determining intensity of aerobic
training?
Heart rate
Calories burned
Oxygen consumption
Change in cardiac output
3. In a training scenario, if an athlete experiences a sudden stretch in their
muscle during a high-intensity workout, which structure would be
primarily responsible for triggering a protective response?
extrafusal muscle fiber
Pacinian corpuscle
muscle spindle
, GTO
4. What should be evaluated FIRST when designing a training program for a
68-year-old competitive female tennis player?
cardiovascular fitness
, lower body strength
balance and agility
Medical history
5. Describe the role of the muscle spindle in the stretch reflex mechanism.
The muscle spindle is responsible for muscle contraction during
exercise.
The muscle spindle stores energy for muscle contractions.
The muscle spindle detects rapid changes in muscle length and
sends signals to initiate the stretch reflex, helping to maintain
muscle tone and protect against injury.
The muscle spindle regulates blood flow to the muscles during
activity.
6. If an athlete is looking to improve their explosive power for sprinting,
which plyometric drill should they prioritize based on intensity?
bounds
box jumps
jumps in place
depth jumps
7. If an athlete shows limited flexibility in the hamstrings during the sit-and-
reach test, what training approach should be implemented to address this
issue?
Increase the weight in their strength training program.
Reduce the frequency of their training sessions.
Incorporate targeted stretching exercises for the hamstrings
into their training regimen.
, Focus solely on cardiovascular training.
8. What is the primary energy system responsible for producing ATP rapidly
during high-intensity exercise?
fat oxidation
phosphagen
fast glycolysis
aerobic glycolysis
9. What type of lever is primarily involved in elbow flexion and extension
during concentric isokinetic exercises?
2nd class
1st class
3rd class
All of the above
10. Which of the following structures detects rapid movement and initiates
the stretch reflex?
Extrafusal muscle fiber
GTO
Muscle spindle
Pacinian corpuscle (encapsulated sensory nerve ending that acts
as a receptor for vibration and pressure)
11. Which phase of the stretch-shortening cycle involves the rapid transition
between eccentric and concentric actions?
concentric
eccentric
