NASM-CPT Exercise Science Fundamentals 3

Question 1

What is the approximate MET value of a person walking at 3.5 mph on a flat surface?

Accepted Answer

3–4 METs

Answer

Brisk walking at 3.5 mph corresponds to approximately 3–4 METs, classifying it as light-to-moderate intensity physical activity.

Question 2

The epimysium is the connective tissue sheath that surrounds:

Accepted Answer

The entire muscle

Answer

The epimysium is the outermost connective tissue layer that encases the entire muscle belly.

Question 3

Which neurotransmitter is released at the neuromuscular junction to initiate muscle contraction?

Accepted Answer

Acetylcholine

Answer

Acetylcholine (ACh) is released by motor neurons at the neuromuscular junction, binding to receptors on the muscle fiber to trigger depolarization.

Question 4

Excess post-exercise oxygen consumption (EPOC) is primarily associated with:

Accepted Answer

Replenishing oxygen stores and restoring homeostasis after intense exercise

Answer

EPOC represents the elevated oxygen consumption after exercise used to restore phosphocreatine, clear lactate, and re-establish homeostasis.

Question 5

Which of the following best defines 'motor unit'?

Accepted Answer

A motor neuron and all the muscle fibers it innervates

Answer

A motor unit consists of one alpha motor neuron and all the skeletal muscle fibers it controls, functioning as the basic unit of muscular force production.
