UPDATE GRADED A+
1. Which body system is primarily responsible for transporting oxygen and nutrients to
muscles during exercise?
A. Nervous system
B. Digestive system
C. Circulatory system
D. Endocrine system
Answer: C
Rationale: The circulatory system transports oxygen, nutrients, and hormones throughout the
body while removing waste products.
2. Which type of muscle contraction occurs when the muscle lengthens while producing
force?
A. Concentric contraction
B. Eccentric contraction
C. Isometric contraction
D. Static contraction
Answer: B
Rationale: Eccentric contraction occurs when a muscle lengthens while under tension, such
as lowering a dumbbell during a curl.
3. What is the recommended warm-up duration before engaging in intense exercise?
A. 2–3 minutes
B. 5–10 minutes
C. 20–30 minutes
D. 40–50 minutes
Answer: B
Rationale: A warm-up lasting 5–10 minutes prepares the cardiovascular system, increases
muscle temperature, and reduces injury risk.
4. Which energy system is primarily used during short, explosive activities lasting under
10 seconds?
A. Aerobic system
B. Glycolytic system
C. Oxidative system
D. ATP-PC system
,Answer: D
Rationale: The ATP-PC system supplies immediate energy for very short bursts of high-
intensity activities such as sprinting or jumping.
5. What does BMI stand for?
A. Body Mass Index
B. Body Muscle Indicator
C. Basic Metabolic Intake
D. Body Motion Integration
Answer: A
Rationale: BMI is a calculation using weight and height to estimate body fat levels and
classify weight status.
6. Which nutrient is the body's primary source of energy during moderate-intensity
exercise?
A. Protein
B. Vitamins
C. Carbohydrates
D. Minerals
Answer: C
Rationale: Carbohydrates are quickly broken down into glucose, providing readily available
energy for muscles.
7. Which component of fitness refers to the ability of muscles to exert force repeatedly
over time?
A. Muscular endurance
B. Flexibility
C. Power
D. Speed
Answer: A
Rationale: Muscular endurance is the capacity of muscles to perform repeated contractions
without fatigue.
8. Which type of stretching involves holding a stretch position for 15–60 seconds?
A. Static stretching
B. Dynamic stretching
C. Ballistic stretching
D. Active stretching
Answer: A
Rationale: Static stretching involves slowly stretching a muscle and holding the position for a
period of time.
, 9. Which organ pumps blood throughout the body?
A. Lungs
B. Heart
C. Liver
D. Kidneys
Answer: B
Rationale: The heart is a muscular organ responsible for pumping oxygenated blood to
tissues and returning deoxygenated blood to the lungs.
10. Which type of exercise primarily improves cardiovascular endurance?
A. Weightlifting
B. Sprinting for 5 seconds
C. Long-distance running
D. Isometric holds
Answer: C
Rationale: Long-distance running strengthens the heart and lungs and improves aerobic
endurance.
11. Which mineral is essential for bone strength and muscle contraction?
A. Sodium
B. Iron
C. Calcium
D. Potassium
Answer: C
Rationale: Calcium plays a critical role in bone formation and muscle contraction processes.
12. What does the FITT principle stand for?
A. Frequency, Intensity, Time, Type
B. Flexibility, Intensity, Training, Technique
C. Force, Interval, Tempo, Training
D. Fitness, Improvement, Technique, Training
Answer: A
Rationale: The FITT principle is a guideline for designing exercise programs based on
frequency, intensity, time, and type.
13. Which muscle is primarily responsible for extending the knee?
A. Hamstrings
B. Quadriceps
C. Gluteus maximus
D. Gastrocnemius
, Answer: B
Rationale: The quadriceps group located on the front of the thigh extends the knee joint.
14. Which macronutrient is mainly responsible for muscle repair and growth?
A. Carbohydrates
B. Protein
C. Fats
D. Water
Answer: B
Rationale: Protein supplies amino acids that repair damaged muscle fibers and promote
muscle growth.
15. What is the normal resting heart rate range for most healthy adults?
A. 20–40 beats per minute
B. 40–50 beats per minute
C. 60–100 beats per minute
D. 120–150 beats per minute
Answer: C
Rationale: Most healthy adults have a resting heart rate between 60 and 100 beats per
minute.
16. Which training method alternates periods of high-intensity exercise with rest or low-
intensity activity?
A. Circuit training
B. Continuous training
C. Resistance training
D. Interval training
Answer: D
Rationale: Interval training alternates intense exercise periods with recovery periods to
improve cardiovascular fitness.
17. Which joint type allows movement in many directions, such as the shoulder?
A. Hinge joint
B. Pivot joint
C. Ball-and-socket joint
D. Gliding joint
Answer: C
Rationale: Ball-and-socket joints allow movement in multiple directions and rotation.
18. Which body system controls muscle movement through electrical signals?
