AFAA AFAA 2 — Questions and Answers
Question 1: According to AFAA guidelines, what is the recommended minimum rest period between high-intensity interval training (HIIT) sessions?
- 24 hours
- 48 hours (Correct answer)
- 72 hours
- 96 hours
Correct answer: 48 hours
AFAA recommends at least 48 hours of recovery between high-intensity sessions to allow adequate muscle repair and prevent overtraining.
Question 2: Which muscle is the primary stabilizer of the lumbar spine during standing aerobic exercise?
- Rectus abdominis
- Transverse abdominis (Correct answer)
- External oblique
- Erector spinae
Correct answer: Transverse abdominis
The transverse abdominis acts as a deep stabilizing corset for the lumbar spine and should be activated before dynamic movement.
Question 3: When an AFAA-certified instructor modifies a jump squat for a participant with knee pain, which substitution is most appropriate?
- Weighted squat
- Step touch with squat (Correct answer)
- Lunge jump
- Box step-up
Correct answer: Step touch with squat
A step touch with squat eliminates impact while maintaining lower-body engagement, making it a safe regression for participants with knee issues.
Question 4: What does the FITT principle acronym stand for in exercise programming?
- Frequency, Intensity, Time, Type (Correct answer)
- Force, Interval, Tension, Training
- Frequency, Interval, Time, Technique
- Force, Intensity, Time, Type
Correct answer: Frequency, Intensity, Time, Type
FITT stands for Frequency, Intensity, Time, and Type — the four variables used to design and progress an exercise program.
Question 5: During a group fitness class, a participant becomes pale, sweaty, and reports feeling dizzy. The instructor's FIRST action should be to:
- Call 911 immediately
- Have the participant sit or lie down (Correct answer)
- Offer the participant water and continue class
- Check the participant's pulse rate
Correct answer: Have the participant sit or lie down
The immediate priority is preventing a fall by having the participant sit or lie down, then assessing further and summoning help if needed.
Question 6: Which energy system is the PRIMARY source during the first 10 seconds of maximal effort exercise?
- Aerobic oxidative system
- Glycolytic system
- Phosphagen (ATP-PCr) system (Correct answer)
- Beta-oxidation pathway
Correct answer: Phosphagen (ATP-PCr) system
The phosphagen system uses stored ATP and phosphocreatine for immediate, explosive energy during the first 10 seconds of maximal effort.
Question 7: According to AFAA standards, what is the minimum cueing time an instructor should provide before a movement transition?
- 1 count
- 2 counts
- 4 counts (Correct answer)
- 8 counts
Correct answer: 4 counts
AFAA recommends providing at least 4 counts of advance cueing before a movement change to allow participants to prepare safely.
