NCCPT Special Populations and Modifications 2 — Questions and Answers
Question 1: Which MET (metabolic equivalent of task) range is classified as moderate-intensity exercise?
- 1–2 METs
- 3–6 METs (Correct answer)
- 7–10 METs
- 11–14 METs
Correct answer: 3–6 METs
Moderate-intensity exercise is defined as 3–6 METs, representing a moderate increase above resting metabolic rate.
Question 2: For a client with chronic obstructive pulmonary disease (COPD), which breathing technique is most recommended during exertion?
- Breath holding at peak effort
- Pursed-lip breathing (Correct answer)
- Rapid hyperventilation
- Diaphragmatic restriction
Correct answer: Pursed-lip breathing
Pursed-lip breathing slows the exhalation rate, reduces air trapping (dynamic hyperinflation), and improves gas exchange in COPD clients.
Question 3: When a client with fibromyalgia begins an exercise program, which initial approach has the strongest evidence for improving symptoms?
- High-intensity interval training
- Heavy compound resistance training
- Low-intensity aerobic exercise (Correct answer)
- Plyometric training
Correct answer: Low-intensity aerobic exercise
Low-intensity aerobic exercise is the most evidence-supported starting point for fibromyalgia, improving pain and function without triggering post-exertional flares.
Question 4: Which exercise modality is most appropriate for a client with osteoarthritis of the knee?
- High-impact running on pavement
- Jumping and plyometric drills
- Low-impact aerobic exercise (e.g., cycling, swimming) (Correct answer)
- Heavy loaded squats
Correct answer: Low-impact aerobic exercise (e.g., cycling, swimming)
Low-impact aerobic exercise maintains cardiovascular fitness and joint mobility while minimizing compressive forces on the arthritic knee joint.
Question 5: Before a client who has experienced a myocardial infarction returns to exercise, what is most important?
- Client preference and motivation alone
- Physician clearance and a cardiac rehabilitation protocol (Correct answer)
- Age and BMI assessment only
- A fitness assessment performed by the trainer
Correct answer: Physician clearance and a cardiac rehabilitation protocol
Post-MI clients require physician clearance and should follow a structured cardiac rehabilitation protocol to safely progress exercise intensity.
Question 6: When training a client with hypertension, which activity warrants the most caution?
- Brisk walking
- Lap swimming
- Heavy isometric exercises (e.g., sustained wall sits with straining) (Correct answer)
- Light stationary cycling
Correct answer: Heavy isometric exercises (e.g., sustained wall sits with straining)
Heavy isometric contractions with the Valsalva maneuver can cause acute, sharp spikes in blood pressure, which is particularly dangerous in hypertensive clients.
Question 7: What is the primary mechanism by which balance training reduces fall risk in elderly clients?
- Improved bone mineral density alone
- Enhanced proprioception and postural control (Correct answer)
- Reduced resting heart rate
- Increased muscle hypertrophy
Correct answer: Enhanced proprioception and postural control
Balance training improves proprioceptive feedback and postural control systems, allowing older adults to detect and correct postural disturbances before falls occur.
