1. Q: What is the definition of wellness? CORRECT ANSWER Wellness is a
multidimensional state of being describing the positive health of an individual
as exemplified by quality of life and a sense of well-being.
2. Q: What are the five components of health-related physical fitness?
CORRECT ANSWER Cardiorespiratory endurance, muscular strength, muscular
endurance, flexibility, and body composition.
3. Q: What is the primary energy system used during high-intensity exercise
lasting 10 seconds or less? CORRECT ANSWER The phosphagen (ATP-PC)
system.
4. Q: What is the primary energy system used during maximal exercise lasting
approximately 30 seconds to 2 minutes? CORRECT ANSWER The glycolytic
(lactic acid) system.
5. Q: What is the primary energy system used during low-intensity, long-
duration aerobic activity? CORRECT ANSWER The oxidative (aerobic) system.
6. Q: What is the definition of VO₂ max? CORRECT ANSWER The maximum
volume of oxygen the body can consume during maximal exercise; it is the best
indicator of cardiorespiratory fitness.
7. Q: What is the Fick equation? CORRECT ANSWER VO₂ = Cardiac Output ×
Arteriovenous Oxygen Difference (a-vO₂ diff).
8. Q: What is stroke volume? CORRECT ANSWER The amount of blood ejected
from the left ventricle per heartbeat.
9. Q: What is cardiac output? CORRECT ANSWER The volume of blood
pumped by the heart per minute (Heart Rate × Stroke Volume).
,10. Q: What is the Karvonen formula used for? CORRECT ANSWER To
calculate target heart rate using heart rate reserve: THR = [(HRmax − HRrest) ×
%intensity] + HRrest.
11. Q: What is the average resting heart rate for a healthy adult? CORRECT
ANSWER 60–100 beats per minute.
12. Q: What is the definition of tidal volume? CORRECT ANSWER The amount
of air inhaled or exhaled during normal breathing.
13. Q: What is the primary muscle of respiration? CORRECT ANSWER The
diaphragm.
14. Q: What is the definition of anaerobic threshold? CORRECT ANSWER The
exercise intensity at which lactate begins to accumulate in the blood faster
than it can be removed.
15. Q: What is EPOC (Excess Post-exercise Oxygen Consumption)? CORRECT
ANSWER The elevated oxygen consumption following exercise as the body
restores itself to resting levels.
16. Q: What is the overload principle? CORRECT ANSWER A training principle
stating that a greater-than-normal stress or load on the body is required for a
training adaptation to take place.
17. Q: What is the principle of progression? CORRECT ANSWER The
systematic increase in training stress over time to continue making
adaptations.
18. Q: What is the principle of specificity? CORRECT ANSWER The body
adapts to the particular type and mode of exercise imposed (SAID principle).
19. Q: What is the principle of reversibility? CORRECT ANSWER Fitness gains
are lost when training stops; also known as the "use it or lose it" principle.
20. Q: What is the principle of individual differences? CORRECT ANSWER
People respond differently to the same training stimulus based on genetics,
age, sex, and other factors.
21. Q: What is the difference between muscular strength and muscular
endurance? CORRECT ANSWER Strength is the maximal force a muscle can
generate; endurance is the ability to sustain repeated contractions over time.
, 22. Q: What is the definition of power? CORRECT ANSWER The rate at which
work is performed (Force × Velocity).
23. Q: What is the all-or-none principle? CORRECT ANSWER A muscle fiber
either contracts maximally or does not contract at all in response to a stimulus.
24. Q: What is a motor unit? CORRECT ANSWER A motor neuron and all the
muscle fibers it innervates.
25. Q: What is the sliding filament theory? CORRECT ANSWER The theory that
muscle contraction occurs when actin and myosin filaments slide past each
other, shortening the sarcomere.
26. Q: What is the role of ATP in muscle contraction? CORRECT ANSWER ATP
provides the energy for myosin heads to bind to actin and pull the filaments.
27. Q: What is the definition of hypertrophy? CORRECT ANSWER An increase
in muscle size due to an increase in the size of individual muscle fibers.
28. Q: What is the definition of atrophy? CORRECT ANSWER A decrease in
muscle size due to disuse or immobilization.
29. Q: What is DOMS (Delayed Onset Muscle Soreness)? CORRECT ANSWER
Muscle soreness that peaks 24–72 hours after unfamiliar or intense exercise,
primarily caused by eccentric muscle actions.
30. Q: What is the difference between concentric and eccentric muscle
actions? CORRECT ANSWER Concentric: muscle shortens under tension.
Eccentric: muscle lengthens under tension.
31. Q: What is an isometric muscle action? CORRECT ANSWER Muscle tension
is generated without a change in muscle length (static contraction).
32. Q: What is the recommended exercise intensity range for improving
cardiorespiratory fitness in apparently healthy adults? CORRECT ANSWER 50–
85% of heart rate reserve or 40–85% of VO₂ reserve.
33. Q: What is the talk test? CORRECT ANSWER A subjective method of
monitoring exercise intensity where a client should be able to speak
comfortably but not sing during moderate-intensity exercise.
34. Q: What is the Borg RPE scale range? CORRECT ANSWER 6–20, where 6 is
no exertion and 20 is maximal exertion.
