AFAA MCQ 4 — Questions and Answers
Question 1: Which of the following best describes plyometric exercise?
- Slow, controlled movements through a full range of motion
- Explosive movements that use the stretch-shortening cycle (Correct answer)
- Low-impact movements performed in water
- Isometric holds at end-range positions
Correct answer: Explosive movements that use the stretch-shortening cycle
Plyometric exercises involve explosive, rapid movements that utilize the stretch-shortening cycle to generate power.
Question 2: What is the correct neutral spine position during standing exercises?
- Flat back with no lumbar curve
- Natural S-curve with slight lumbar lordosis (Correct answer)
- Exaggerated lumbar arch
- Rounded thoracic spine with forward head
Correct answer: Natural S-curve with slight lumbar lordosis
Neutral spine preserves the natural S-curve of the spine, including slight lumbar lordosis, reducing injury risk.
Question 3: How does music tempo (BPM) affect the design of a high/low aerobics class?
- Higher BPM always produces lower intensity
- BPM determines the pace of movement and appropriate exercise selection (Correct answer)
- BPM has no effect on exercise safety
- Music tempo should never exceed 80 BPM in group exercise
Correct answer: BPM determines the pace of movement and appropriate exercise selection
Music tempo sets the movement pace, influencing exercise intensity and which choreography options are safe and effective.
Question 4: What is the primary benefit of incorporating balance training into a group fitness class?
- Maximizes caloric expenditure
- Improves proprioception and reduces fall risk (Correct answer)
- Increases muscle hypertrophy
- Elevates cardiovascular fitness
Correct answer: Improves proprioception and reduces fall risk
Balance training enhances proprioception — the body's sense of position — which reduces fall risk especially in older adults.
Question 5: When designing a step aerobics class, what is the recommended bench height for beginners?
- 12–14 inches
- 10–12 inches
- 4–6 inches
- 6–8 inches (Correct answer)
Correct answer: 6–8 inches
Beginners in step aerobics should start with a 6–8 inch bench height to learn technique safely before progressing.
Question 6: Which of the following is an example of a compound exercise?
- Bicep curl
- Leg press (Correct answer)
- Lateral raise
- Calf raise
Correct answer: Leg press
A leg press is a compound exercise because it involves movement at multiple joints (hip and knee).
Question 7: What does the term 'interval training' refer to in group exercise?
- Exercise performed at a single steady pace for the entire session
- Alternating periods of higher and lower intensity work (Correct answer)
- Stretching between each aerobic set
- A rest period of 10 minutes between exercises
Correct answer: Alternating periods of higher and lower intensity work
Interval training alternates between higher-intensity efforts and lower-intensity recovery periods within the same session.
