NASM-CPT Exercise Science Fundamentals 2 — Questions and Answers
Question 1: Which term describes the ability of the nervous system to sense and control body position in space?
- Proprioception (Correct answer)
- Kinesthesia
- Neuromuscular efficiency
- Interoception
Correct answer: Proprioception
Proprioception refers to the body's ability to sense its own position, movement, and equilibrium through receptors in muscles, joints, and tendons.
Question 2: The force-velocity relationship in muscle physiology states that:
- Force increases linearly with velocity
- Maximum force is produced at zero velocity (isometric) (Correct answer)
- Faster contractions generate greater peak force
- Velocity has no effect on force production
Correct answer: Maximum force is produced at zero velocity (isometric)
According to the force-velocity curve, peak muscle force is generated when velocity is zero (isometric contraction), and force decreases as contraction speed increases.
Question 3: Which plane of motion divides the body into left and right halves?
- Frontal plane
- Transverse plane
- Sagittal plane (Correct answer)
- Diagonal plane
Correct answer: Sagittal plane
The sagittal plane divides the body into left and right portions; movements in this plane include flexion and extension.
Question 4: Which hormone is primarily responsible for regulating blood glucose levels by promoting cellular glucose uptake?
- Glucagon
- Cortisol
- Insulin (Correct answer)
- Epinephrine
Correct answer: Insulin
Insulin, secreted by the pancreatic beta cells, signals cells to take up glucose from the bloodstream, lowering blood sugar levels.
Question 5: What does the term 'agonist' refer to in the context of muscle function?
- A muscle that opposes the primary mover
- A muscle that assists stabilization
- The primary muscle responsible for a movement (Correct answer)
- A muscle that is reflexively inhibited
Correct answer: The primary muscle responsible for a movement
An agonist (prime mover) is the muscle primarily responsible for producing a given movement, generating the majority of the force required.
Question 6: Which connective tissue structure connects muscle to bone?
- Ligament
- Fascia
- Cartilage
- Tendon (Correct answer)
Correct answer: Tendon
Tendons are dense connective tissue structures that transmit the forces generated by muscle contraction to the bones, producing movement.
