• What is the primary function of the cardiovascular system during

exercise?

• To provide lubrication to joints
• To deliver oxygen and nutrients to tissues
• To increase body temperature
• To control hormone production

Rationale: The cardiovascular system’s main role is to transport oxygen

and nutrients to active muscles and remove waste products during exercise.

• Which of the following energy systems is primarily used during a 100-

meter sprint?

• Aerobic system
• ATP-PC system
• Glycolytic system
• Oxidative phosphorylation

Rationale: The ATP-PC system provides immediate energy for short,

explosive activities lasting up to 10 seconds.

3. The term “hypertrophy” refers to:

• Increased fat storage
• Increase in muscle fiber size
• Muscle wasting
• Improved flexibility

Rationale: Hypertrophy is the enlargement of muscle fibers due to strength

training and increased workload.

• Which type of muscle contraction occurs when the muscle lengthens

under tension?

• Isometric
• Concentric
• Eccentric
• Static 2 / 4

Rationale: Eccentric contractions involve muscle lengthening while

generating force, often during the lowering phase of movements.

5. The primary plane of motion for a bicep curl is:

• Sagittal plane
• Frontal plane
• Transverse plane
• Coronal plane

Rationale: The sagittal plane divides the body into left and right halves and

involves flexion and extension movements like bicep curls.

• What is the recommended rest period for muscular endurance training?
• 3–5 minutes
• 2–3 minutes
• 30–60 seconds
• 5–10 seconds

Rationale: Short rest intervals (30–60 seconds) are optimal for endurance

to maintain metabolic stress and stamina.

• Which nutrient is the body’s preferred source of energy during high-

intensity exercise?

• Fat 3 / 4

• Carbohydrates
• Protein
• Water

Rationale: Carbohydrates provide quick energy through glycolysis, making

them ideal for intense activity.

8. The term “VO₂ max” refers to:

• Resting heart rate
• The amount of carbon dioxide expelled
• The maximum oxygen uptake during intense exercise
• The speed at which the heart beats

Rationale: VO₂ max measures the body’s capacity to use oxygen, indicating

aerobic endurance.

• Which of the following is an example of an assessment for muscular

strength?

• 1.5-mile run
• One-repetition maximum (1RM) test
• Sit-and-reach test
• Skinfold test

Rationale: The 1RM test measures the maximum force a muscle can

generate in a single effort, indicating strength.
