QUESTIONS AND CORRECT ANSWERS

EXAM
1. The body’s automatic tendency to maintain a constant, internal bodily
environment through various processes is called:
a) Metabolism
b) Homeostasis
c) Homeokinesis
d) Glycolysis
Correct Answer: b) Homeostasis
Rationale: Homeostasis is the maintenance of stable internal conditions. While the body
is dynamic, it constantly works to keep variables like temperature and pH within a
narrow range.
2. Which of the following is responsible for sensing muscular tension and
preventing the muscle from being placed under excessive stress?
a) Muscle spindles
b) Golgi Tendon Organs (GTO)
c) Pacinian corpuscles
d) Alpha motor neurons
Correct Answer: b) Golgi Tendon Organs (GTO)
Rationale: The GTO is located at the musculotendinous junction and senses tension.
When tension becomes too high, it inhibits the motor neuron (autogenic inhibition) to
relax the muscle and prevent injury.
,3. If a client has a "swayback" appearance, or an excessive anterior tilt of the
pelvis, they are likely exhibiting:
a) Kyphosis
b) Scoliosis
c) Lordosis
d) Flatback syndrome
Correct Answer: c) Lordosis
Rationale: Lordosis refers to the inward curvature of the spine. In the lumbar spine,
excessive lordosis presents as an anterior pelvic tilt, where the glutes stick out and the
stomach protrudes forward.
4. Which energy system provides the majority of ATP for activities lasting longer
than 3 minutes, such as a 5k run?
a) ATP-PC System
b) Anaerobic Glycolysis
c) Oxidative (Aerobic) System
d) Creatine Phosphate System
Correct Answer: c) Oxidative (Aerobic) System
Rationale: The oxidative system uses oxygen to metabolize carbohydrates and fats. It is
the primary system for endurance activities because it produces a large amount of ATP,
albeit slowly.
5. Type IIx (or IIb) muscle fibers are characterized by:
a) High oxidative capacity and low force production
b) High glycolytic capacity and fast fatigue
c) High capillary density and myoglobin content
d) Slow contraction speed and high endurance
Correct Answer: b) High glycolytic capacity and fast fatigue
Rationale: Type IIx fibers are "fast glycolytic." They are designed for explosive power and
speed but fatigue very quickly due to their reliance on anaerobic metabolism.
, 6. A contraction where the muscle lengthens under tension (e.g., the lowering
phase of a bicep curl) is called:
a) Concentric
b) Isometric
c) Isokinetic
d) Eccentric
Correct Answer: d) Eccentric
Rationale: Eccentric contractions occur when the force applied to the muscle is greater
than the force produced by the muscle, causing it to lengthen. These contractions are
responsible for the majority of muscle soreness (DOMS).
7. Which law of motion states that for every action, there is an equal and opposite
reaction?
a) Law of Inertia
b) Law of Acceleration
c) Law of Reaction
d) Law of Gravitation
Correct Answer: c) Law of Reaction (Newton's 3rd Law)
Rationale: In exercise, this explains ground reaction forces. When you push down against
the ground during a squat, the ground pushes back up with equal force, allowing you to
move.
8. The ability of the neuromuscular system to allow optimal levels of motor unit
recruitment and muscle contraction at the correct time is known as:
a) Muscular endurance
b) Neuromuscular efficiency
c) Cardiovascular drift
d) Mitochondrial density
Correct Answer: b) Neuromuscular efficiency
Rationale: This is the nervous system's ability to communicate effectively with the
muscles to produce coordinated, efficient movement. Training improves this efficiency.
