AFAA Trivia 5 — Questions and Answers
Question 1: What does the term 'muscle hypertrophy' refer to in the context of resistance training?
- An increase in muscle fiber size (Correct answer)
- A decrease in muscle fiber number
- Improved muscle flexibility
- Increased neural recruitment efficiency
Correct answer: An increase in muscle fiber size
Muscle hypertrophy is the enlargement of individual muscle fibers in response to resistance training overload.
Question 2: Which stretching technique involves alternating contraction and relaxation of a muscle before stretching, often used in advanced fitness programs?
- Proprioceptive Neuromuscular Facilitation (PNF) (Correct answer)
- Ballistic stretching
- Static stretching
- Dynamic stretching
Correct answer: Proprioceptive Neuromuscular Facilitation (PNF)
PNF stretching uses alternating muscle contraction and relaxation to achieve greater flexibility gains than passive static stretching alone.
Question 3: In AFAA group fitness programming, what is a 'pre-choreographed' class format?
- A class with routines designed and distributed by a program provider (Correct answer)
- A class improvised entirely by the instructor
- A class based solely on participant requests
- A class using only equipment-based exercises
Correct answer: A class with routines designed and distributed by a program provider
Pre-choreographed formats (like Les Mills programs) provide instructors with set routines, music, and coaching cues from a central provider.
Question 4: What is the primary function of the cardiovascular system during aerobic exercise?
- Delivering oxygen and nutrients to working muscles while removing waste products (Correct answer)
- Producing ATP for immediate energy use
- Regulating body temperature through sweating
- Coordinating muscle fiber recruitment patterns
Correct answer: Delivering oxygen and nutrients to working muscles while removing waste products
The cardiovascular system delivers oxygen and glucose to working muscles and removes CO2 and metabolic byproducts during aerobic exercise.
Question 5: Which of the following best describes 'interval training' as recognized by AFAA?
- Alternating periods of higher and lower intensity exercise (Correct answer)
- Continuous exercise at a steady moderate pace
- Training only one muscle group per session
- Exercising exclusively at maximum heart rate
Correct answer: Alternating periods of higher and lower intensity exercise
Interval training alternates between high-intensity efforts and lower-intensity recovery periods, improving both aerobic and anaerobic fitness.
Question 6: What does AFAA recommend instructors do before designing an exercise program for a new participant?
- Conduct a health history screening and PAR-Q assessment (Correct answer)
- Measure body fat percentage immediately
- Begin with a maximum effort fitness test
- Prescribe a standard program based on age alone
Correct answer: Conduct a health history screening and PAR-Q assessment
AFAA requires a health history screening including the PAR-Q (Physical Activity Readiness Questionnaire) to identify any contraindications before programming.
Question 7: Which plane of motion divides the body into front and back halves, and is associated with lateral movements in aerobics?
- Frontal (coronal) plane (Correct answer)
- Sagittal plane
- Transverse plane
- Diagonal plane
Correct answer: Frontal (coronal) plane
The frontal (coronal) plane divides the body into anterior and posterior halves; lateral movements like side steps and jumping jacks occur in this plane.
