SECTION 1: BASIC AND APPLIED SCIENCES
Question 1
A participant in a group fitness class begins to exhibit signs of lightheadedness,
nausea, and clammy skin. The trainer recognizes these as early symptoms of
which condition?
A. Heat exhaustion
B. Hypoglycemia
C. Dehydration
D. All of the above
Correct Answer: D
Rationale: Early signs of heat exhaustion, hypoglycemia, and dehydration can
overlap significantly. Lightheadedness, nausea, and clammy skin are common to
all three conditions. Immediate assessment of the participant's recent food intake,
fluid consumption, and environmental conditions is necessary.
Question 2
Which energy system is primarily used during a 400-meter sprint lasting
approximately 60 seconds?
A. ATP-PC system
B. Glycolytic system
,C. Oxidative system
D. Beta-oxidation system
Correct Answer: B
Rationale: The glycolytic system (anaerobic glycolysis) is the primary energy source
for high-intensity activities lasting 30 seconds to 2 minutes. The ATP-PC system is
utilized for maximal efforts up to 10 seconds. The oxidative system is used for
longer duration activities lasting more than 2 minutes. Beta-oxidation is a
component of the oxidative system.
Question 3
A participant performing a squat with poor form exhibits excessive forward lean
during the ascent phase. Which muscle group is most likely underactive?
A. Gluteus maximus
B. Quadriceps
C. Hamstrings
D. Erector spinae
Correct Answer: A
Rationale: Excessive forward lean during squat ascent indicates weak or
underactive gluteus maximus. The glutes are responsible for hip extension; when
they are underactive, the torso compensates by leaning forward to shift the center
of mass posteriorly. Quadriceps are the primary knee extensors, not hip extensors.
Hamstrings are hip extensors but are less involved in squat mechanics than the
glutes.
Question 4
A group fitness class includes high-intensity interval training (HIIT). The trainer
,instructs participants to perform 30 seconds of maximal effort followed by 90
seconds of recovery. This work-to-rest ratio primarily targets which energy
system?
A. ATP-PC system
B. Glycolytic system
C. Oxidative system
D. Aerobic system
Correct Answer: B
Rationale: Work-to-rest ratios of 1:3 or 1:4 allow sufficient recovery to replenish
ATP and phosphocreatine while still challenging the glycolytic system. The intensity
and duration of the work intervals cause lactate accumulation. The oxidative
system is not the primary target for short, high-intensity intervals.
Question 5
A participant reports a history of lower back pain. Which cue during a deadlift
would be most appropriate to protect the lumbar spine?
A. Maintain a neutral spine throughout the movement
B. Extend the spine at the top of the movement
C. Keep the head looking upward
D. Hold the breath during the entire lift
Correct Answer: A
Rationale: Maintaining a neutral spine reduces stress on the lumbar discs and
ligaments. Excessive extension at the top (hyperextension) increases compression
forces on the facet joints. Looking upward causes cervical extension, which does
not protect the lumbar spine. Holding the breath without proper bracing does not
protect the spine.
, Question 6
A participant in a group fitness class consistently experiences knee pain during
lunges. The trainer observes that the participant's knee tracks inward during the
movement. This valgus collapse is most likely due to weakness in which muscle
group?
A. Adductors
B. Quadriceps
C. Gluteus medius
D. Hamstrings
Correct Answer: C
Rationale: Gluteus medius is responsible for hip abduction and external rotation.
Weakness in this muscle causes the femur to adduct and internally rotate during
weight-bearing activities, leading to knee valgus (inward tracking). Strengthening
the gluteus medius is essential to correct this movement dysfunction.
Question 7
A participant has a resting heart rate of 72 beats per minute and a maximum heart
rate of 186 beats per minute. Using the Karvonen method, what is their target
heart rate zone at 75% intensity?
A. 147 bpm
B. 158 bpm
C. 166 bpm
D. 172 bpm
Correct Answer: B
Rationale: Karvonen formula: Target HR = [(MHR - RHR) × intensity] + RHR.
Calculation: [(186 - 72) × 0.75] + 72 = (114 × 0.75) + 72 = 85.5 + 72 = 157.5,
rounded to 158 bpm.
