Section 1: Exercise Physiology
Q1: What is the primary energy system used during aerobic exercise?
A: The aerobic energy system (oxidative system) is the primary energy source,
utilizing oxygen to break down carbohydrates and fats for sustained energy.
,Q2: Which muscle fiber type is most engaged during endurance activities?
A: Type I (slow-twitch) muscle fibers are most engaged, as they are fatigue-resistant
and efficient in using oxygen.
Q3: What is the recommended heart rate range for aerobic training?
A: Typically 50-85% of maximum heart rate (HRmax), calculated as 220 - age for the
general population.
Q4: What is the role of lactic acid in exercise?
A: Lactic acid is a byproduct of anaerobic metabolism that can cause muscle fatigue
but is also used as an energy source once oxygen is available.
Section 2: Anatomy & Kinesiology
Q5: What is the function of the rectus abdominis?
A: The rectus abdominis is responsible for trunk flexion, such as in crunches.
Q6: Which joint is primarily involved in a squat?
A: The knee joint (hinge joint) plays a major role, along with the hip joint (ball-and-
socket).
Q7: What is the difference between concentric and eccentric muscle contractions?
A:
Concentric contraction shortens the muscle (e.g., lifting a dumbbell in a bicep curl).
Eccentric contraction lengthens the muscle under tension (e.g., lowering a
dumbbell).
Section 3: Cardiovascular Training & Safety
Q8: What is the "talk test" in group fitness?
A: A simple way to monitor intensity: If participants can talk comfortably but not
sing, they are in the aerobic zone.
Q9: What are the ACSM guidelines for cardiovascular exercise?
, A:
150 minutes of moderate-intensity or 75 minutes of vigorous activity per week.
Performed 3-5 days a week for at least 30-60 minutes per session.
Q10: Why is a proper warm-up important?
A: It gradually increases heart rate, improves circulation, and prepares muscles and
joints for exercise, reducing injury risk.
Section 4: Strength Training & Flexibility
Q11: What is the FITT principle?
A:
Frequency: How often (e.g., 3-5 times per week)
Intensity: How hard (e.g., 60-80% max HR)
Time: Duration (e.g., 30-60 minutes)
Type: Mode of exercise (e.g., running, cycling)
Q12: How long should static stretching be held?
A: 15-30 seconds per stretch, ideally after a workout when muscles are warm.
Q13: What is progressive overload in strength training?
A: Gradually increasing resistance, repetitions, or intensity to improve strength and
endurance.
Section 5: Instruction & Cueing
Q14: What are the key components of effective group fitness cueing?
A:
Verbal cues (e.g., “Step touch to the right!”)
Visual cues (e.g., demonstrating the move)
Kinesthetic cues (e.g., hands-on correction if appropriate)
Q15: What are modifications in group fitness?
