NASM SFC Chapter 3 | Science of Flexibility & Stretching
2026 | Questions & Verified Answers | Latest Update |
Graded A+
1. The detection of external or internal stimuli through the stimulation of
specialized receptors is
alchemy
perception
accurate processing
sensation
2. In a fitness training program, how might an understanding of fascial structures
influence the design of stretching routines?
Avoiding any stretching of fascial structures is best to prevent injury.
Using only resistance training will improve flexibility without the need
for stretching.
Incorporating dynamic stretches that engage fascial structures can
enhance flexibility and improve overall movement patterns.
Focusing solely on static stretches will be sufficient for improving
flexibility.
3. Which system indicates whether or not a client is being honest with the
fitness professional about how they are feeling during a session?
Enteric
Exteroceptive
Proprioceptive
Interoceptive
,4. If a fitness trainer is working with a client who exhibits hypermobility, what
considerations should they keep in mind during training?
The trainer should focus on strengthening the muscles around the
joints to provide stability and prevent injury.
The trainer should prioritize flexibility training over strength training.
The trainer should avoid any exercises that involve joint movement.
The trainer should encourage the client to increase their range of
motion further.
5. What is the primary definition of mobility in the context of fitness training?
Muscle strength
Joint motion
Balance
Flexibility
6. If an athlete experiences high levels of stress, what might be a likely
consequence for their performance in flexibility training?
Their performance will remain unchanged.
They will likely improve their flexibility significantly.
They may experience reduced range of motion and increased risk
of injury.
They will become more flexible due to stress relief.
7. Which of the following describes the process of external stimulation that can
be detected by the five senses?
Proprioception
, Apperception
Interoception
Exteroception
8. Which of the following is defined as stretch tolerance?
Increase in tissue length when maintaining a constant stress
accommodating to the discomfort of stretching
9. Which of the following is true of hypermobility?
It is more common in males than females
It refers to having low mobility
It is also referred to as double-jointedness
It means that joints have been overworked
10. Describe how assisted stretching contributes to overall fitness during a
dynamic warm-up.
Assisted stretching does not have any significant impact on fitness.
Assisted stretching primarily focuses on building muscle strength.
Assisted stretching helps to improve flexibility and range of
motion, which can enhance performance and reduce injury risk.
Assisted stretching is mainly used for cooling down after workouts.
11. If a client reports feeling discomfort during a stretching session, how should
a fitness professional utilize their understanding of the nervous system to
address this?
The professional should refer the client to a physician without further
assessment.
